Question 1

Machine will not start, connect or begin the nesting cycle

Accepted Answer

NCG2812E and NCG2812LE; follow the controller actually installed. 1 · Read the actual machine status — Servo power, controller connection or an alarm condition prevents readiness. — Record the alarm number, text, time and controller version. Check external servo-ready/connection indicators and complete the approved startup sequence. 2 · Check the software startup stage — Background services or the supplied licence device are not ready. — The manual describes waiting for the background server and using the supplied SoftDog licence device before opening Nesting software. Follow this only on matching installations; do not bypass licensing or reinstall software as a first response. 3 · Check job, material and operating mode — No valid order is selected, tools/material are not ready, or the wrong mode/channel is active. — Confirm the selected order, actual sheet, tool availability and automatic/channel mode. Compare the displayed active NC path to the intended job. 4 · Check utilities against the machine record — Power/phase sequence or pneumatic conditions do not match the installed variant. — Have an electrician verify supply faults. The manual specifies 380 V; the AC product text specifies 415 V. The manual gives 0.5–0.7 MPa air while the specifications give 6–7 kg/cm². Obtain the machine-specific approved values rather than combining these into one setting. Stop operation for a protection fault. The manual names Sunvega in its startup chapter while the specifications name SYNTEC; do not transfer software commands or parameters without confirming the installed system.

Question 2

Small parts or the sheet move during the final perimeter cut

Accepted Answer

Vacuum-table NCG2812E/LE; general diagnostic possibilities require confirmation. 1 · Identify when movement starts — Holding is inadequate from loading, or deteriorates as the nest separates. — Record the affected part size, nest position, cut stage and vacuum indication. Preserve the NC file and sample; movement alone does not prove the spoilboard is too thin. 2 · Check vacuum activation and zones — The active holding area does not match the sheet, or table vacuum was not established. — Verify the approved vacuum setup before motion. The specifications describe seven valve-controlled table sections. Confirm fitted zone layout and coverage; do not use a pump flow rating as proof of secure clamping. 3 · Inspect the contact surface — Chips, damaged contact surfaces or a poor seal can reduce restraint. — After isolation, clean the workbench and suction interfaces. Have Service assess spoilboard condition, uncovered leakage paths and panel flatness; the files do not provide a universal minimum spoilboard thickness. 4 · Separate leakage from pump performance — A restricted filter, leaking connection or pump fault may reduce available vacuum. — Use the pump-specific inspection route in the next topic. Compare readings under an approved test condition; no universal low-vacuum alarm threshold is established by these files. 5 · Review the nesting process — Part size, cutting sequence and cutting load may exceed the validated holding arrangement. — Have the CAM/process specialist review final release, lead-in, pass strategy and any approved tabs or skin allowance. These are assessment options, not documented settings for this machine; trial only after the workholding is proven. Stop operation immediately if a part moves. Do not hold a part by hand, add loose weights or continue cutting to finish the sheet.

Question 3

Vacuum is weak, uneven between zones or the pump overheats

Accepted Answer

Fitted vacuum pump only; identify its maker, model and lubrication system first. 1 · Compare the table and zone condition — Open zones, poor sealing or damaged/loose connections may create leakage. — Check accessible valves, hoses and connection condition while safely stopped. Record whether the loss affects every zone or only one; let Service test the circuit. 2 · Check cooling and filters — Restricted airflow, contamination or a hot installation area can impair pump operation. — Inspect accessible cooling openings without removing guards while running. The manual requires a ventilated location; pump filters and internal cleaning follow the exact pump manufacturer instructions. 3 · Escalate continued low holding or heat — Pump wear or a supply/drive problem requires diagnosis. — Stop production if restraint is unreliable. Send pump nameplate details, vacuum readings, operating hours and filter/service history. Do not adjust a relief device, vane clearance or lubrication setting from generic advice. Pump service is for qualified personnel after isolation and cooling. The LE brochure describes an oil-cooled pump; the manual illustrates a particular vane/grease service arrangement. Do not apply that service procedure to an unverified pump.

Question 4

Spoilboard surfacing is uneven or Z depth changes after flycutting

Accepted Answer

NCG2812E/LE with the approved sacrificial-board arrangement. 1 · Verify the physical board and datum — The program references an old top surface or a different thickness. — Measure the remaining sacrificial board and actual workpiece. Confirm whether the job references material top or the table using the approved setup record. 2 · Check flatness, cleanliness and holding — Debris, uneven support or insufficient vacuum can produce an uneven surface. — Isolate before cleaning or inspection. Prove secure holding before any trial; request Service assessment where the surface or support is damaged. 3 · Reconcile probe/tool and work offsets — A tool-length or work-coordinate change was omitted after resurfacing. — Use the installed gauge procedure and authorised offset verification. The manual describes G54–G59 settings but supplies no universal touch-plate calculation. 4 · Refer the resurfacing plan to Service — Cutting too deeply or ignoring pin/fixture clearance risks table damage. — Manual §5.3 includes a commissioning example using a 0.2 mm table skim. It is not a minimum board thickness, recurring removal allowance or instruction to remove a pin during routine use. Confirm the actual table and cutter before proceeding. Trained technician only for table surfacing, tramming, reference adjustment or moving positioning devices. Never convert a commissioning example into a routine flycut recipe.

Question 5

Positioning pins or pneumatic components fail to retract

Accepted Answer

Side/rear positioning, suction cups, hood and magazine cylinders only where fitted. 1 · Stop before a collision — A raised pin or extended component remains in the tool/pusher path. — Stop the cycle and identify the physical obstruction. Do not force a pin down, reach under a head or start the sweep to test clearance. 2 · Check air and sequence readiness — Insufficient air, a restriction or an incomplete preceding action prevents motion. — Read the external gauge and current alarm. Confirm the machine-specific pressure and correct stage of the cycle; do not increase pressure to force retraction. 3 · Compare position and control evidence — A sensor, valve, connection or internal cylinder fault may be involved. — Trained technician only: compare physical position with the correct I/O diagram and inspect the pneumatic circuit. The files do not identify a universal input address or bypass method. Consult Service before rectification. Trained technician only for internal diagnosis, calibration or adjustments. Isolate and secure stored-energy loads before access; never bypass an interlock.

Question 6

Automatic loader or lift table stops, mispositions or fails to pick a sheet

Accepted Answer

NCG2812LE automatic loading; NCG2812E only with a verified loading option. 1 · Check the guarded loading area — An obstruction or safety-device condition stops loading. — Confirm the area is clear from outside the guarded zone. The LE specification describes a four-sided lift safety curtain; it does not establish the user-suggested scissor-lift photo-eye arrangement. Never bypass a curtain. 2 · Match the stack to the active job — Incorrect sheet, poor stacking or an unsuitable pickup surface affects feeding. — Check panel identity, dimensions and condition against the selected order. Use the loading limits for the supplied lift; do not infer payload from machine net weight. 3 · Check pickup and pre-positioning condition — Contaminated/damaged cups or vacuum loss prevents a reliable grip. — Isolate before inspecting accessible cups and connections. Do not continue when pickup is insecure; have Service verify vacuum and alignment. 4 · Diagnose the specific failed stage — Lift, pre-positioning, pickup or transfer has not reached the required state. — Record the last completed action and alarm/I/O evidence for Service. The supplied documents confirm the loading system but do not provide component-specific hydraulic or sensor recovery procedures. Keep clear of the lift and sheet path. Trained technician only for hydraulic, sensor and cup adjustments. A raised lift must be secured by the approved method before work beneath it.

Question 7

Unloading pusher jams, scratches melamine or leaves debris

Accepted Answer

NCG2812LE unloading line; NCG2812E pusher/sweeper as equipped. 1 · Stop the obstructed cycle — A loose part, raised pin or occupied discharge area blocks the pusher. — Wait for all movement/tools to stop and isolate before access. Do not pull a panel against an active pusher or repeatedly restart a jam. 2 · Inspect the surfaces and clearance — Trapped chips, damaged contact material or an incorrect physical clearance can mark the panel. — Clean the approved accessible surfaces after isolation. Have Service check the pusher/sweeper alignment and contact condition; no clearance or pressure value is supplied for adjustment here. 3 · Check extraction and hood actuation — Blocked ducting, poor extraction or a cylinder fault prevents cleaning. — The LE specification confirms extraction at the pusher and unload table. Inspect connected hoses and collector operation; technicians diagnose pneumatic hood/sweep movement. Restore extraction before returning to machining. Consult Service before rectification. Trained technician only for internal diagnosis, calibration or adjustments. Isolate and secure stored-energy loads before access; never bypass an interlock.

Question 8

Labels are missing, misplaced or belong to the wrong part

Accepted Answer

NCG2812LE with automatic labelling; only matching task-manager software. 1 · Match the job, sheet and label — A different order or label data set is selected. — Compare one known part ID, orientation and dimensions with the queued job and label preview. Hold mismatched parts for identification. 2 · Verify required associated files — A labelling task or image is missing from its expected relationship. — For the manual’s matching task manager, check the main NC file association to the Label folder and the label picture in its Image folder. Preserve the complete job folder structure; do not rename associated files arbitrarily. 3 · Check the printer and applicator separately — Print failure and physical label-placement failure have different causes. — Record whether a correct label prints but is not applied, or whether printing itself fails. Check accessible consumables/status by the printer manual. Do not assume a brand: the operation manual lists Zebra while the LE brochure lists Honeywell. 4 · Verify software/interface compatibility — The external furniture software or label process configuration is not matched. — The LE brochure requires additional furniture-making software for labelling. Have support confirm the exporter, job format and process association for this installation; a file extension alone does not prove compatibility. Stop automatic labelling/machining if identity is wrong. Printer setup, labeler axes and pneumatic adjustments require the correct equipment manual and authorised support.

Question 9

NC file will not import, the wrong job runs or reverse machining is missing

Accepted Answer

NCG2812E/LE; controller and CAM-version-specific workflows. 1 · Separate order import from machine-code import — An order list is being loaded through the wrong function. — The startup chapter describes XML/CSV order data; task management describes NC-file import. Confirm the intended input stage and compatible export rather than changing an extension. 2 · Check active file and mode — Recent-file selection, wrong station/channel or task status points to another job. — Compare displayed NC path, station, process type and preview with the physical sheet. Channel mode is operator-loaded; automatic mode is task-manager-loaded in the documented interface. 3 · Verify front/back/label associations — The selected process requires supporting files that are absent. — For matching software, inspect the documented Label and Reverse file relationships and process selection. A front-only job does not automatically include reverse machining. 4 · Review code reload and preview — A changed file or offset has not been validated against the new path. — The manual says saved edits can refresh loaded NC code. Stop before editing, preserve the original, inspect the new preview and obtain approved first-piece validation. 5 · Investigate application or connection failure — Controller connection, licence, external exporter or IPC condition needs attention. — Record hardware/firmware and software versions, exact error and recent changes. Use approved removable media. Do not reinstall CAM, change IP settings or restore machine parameters without support. Back up the job before edits. Do not execute unverified NC code or transfer commands from the earlier drilling-machine guide.

Question 10

Homing, X/Y accuracy, oval circles or jagged edges are incorrect

Accepted Answer

Three-axis motion checks for the supplied NCG models; not a universal router calibration procedure. 1 · Separate geometry from workpiece movement — Vacuum slip, wrong geometry or an incorrect datum can resemble axis error. — Check holding, active program dimensions and one known test piece. Record whether the error repeats in the same direction or varies between runs. 2 · Compare coordinate and homing status — Wrong work coordinate or incomplete referencing displaces the job. — Compare the intended G54–G59 selection with the verified setup record. The manual does not provide a machine-specific homing sensor map or universal reset value; refer a failed home to Service. 3 · Inspect the appropriate drive system — Contamination, lubrication failure, looseness or wear can impair motion. — The supplied specifications confirm X/Y rack-and-pinion and a Z ball screw with servo drive. A technician checks these systems; do not diagnose stepper “lost steps” or adjust backlash compensation by assumption. 4 · Request measured geometry checks — Gantry squareness, spindle perpendicularity and drive repeatability are different issues. — Have Service measure them separately. An oval circle does not uniquely diagnose gantry squareness, and spindle tramming is not the same measurement as X/Y squareness. Do not correct a mechanical fault by arbitrary scaling or offsets. Consult Service before rectification. Trained technician only for internal diagnosis, calibration or adjustments. Isolate and secure stored-energy loads before access; never bypass an interlock.

Question 11

Z depth is wrong, tool measurement fails or the router bit slips

Accepted Answer

Installed spindle, holder and gauge only; supplied specifications identify ISO30/ER32 ATC variants. 1 · Stop if tool retention is doubtful — Bit movement, damaged collet/holder or contamination creates an unsafe cut. — Isolate and wait for the spindle to stop. A trained person checks tool shank, correct collet size, seating and holder condition against the spindle/tooling instructions. Do not use a guessed torque. 2 · Check the measured tool and selected tool number — Wrong tool identity, changed projection or a stale length entry changes depth. — Compare the fitted tool with the active tool number and approved measurement record. Re-measure using the actual tool-setting gauge procedure before a test. 3 · Check the workpiece reference — Material thickness, spoilboard resurfacing or the wrong work offset changes the effective Z zero. — Confirm the physical top surface and program datum. Do not substitute a generic touch-plate thickness formula; the files confirm a gauge but do not provide that calibration method. 4 · Escalate mechanical or interface mismatch — Binding Z motion or mismatched holder instructions require service. — Stop for grinding or uncommanded movement. The operation manual mentions an HSK taper while the product specs identify ISO30. Confirm the fitted spindle before any taper cleaning, lubrication or drawbar maintenance procedure. Consult Service before rectification. Trained technician only for internal diagnosis, calibration or adjustments. Isolate and secure stored-energy loads before access; never bypass an interlock.

Question 12

ATC fails, tool clamp confirmation is missing or the magazine jams

Accepted Answer

Verified 12-slot ATC configurations only; manual-tool-change variants are excluded. 1 · Preserve the stopped tool-change state — Tool, magazine or spindle is not in a confirmed safe position. — Stop operation and note the tool number, pocket and last action. Keep clear; do not repeat tool changes or pull a retained tool by hand. 2 · Check approved air and accessible holder condition — Low air, contamination or a damaged holder may interrupt clamping. — Read the gauge and alarm without opening the mechanism. The spindle must be fully stopped before tool handling. Inspect only under the approved isolated procedure. 3 · Request the exact spindle/ATC recovery procedure — Clamp sensor, drawbar, valve/exhaust or magazine positioning needs diagnosis. — Have Service verify feedback and the installed tool interface. The manual discusses spindle valve/exhaust condition but does not establish a universal clamp-sensor input or manual unclamp recovery. Do not energise a valve or bypass feedback. Consult Service before rectification. Trained technician only for internal diagnosis, calibration or adjustments. Isolate and secure stored-energy loads before access; never bypass an interlock.

Question 13

Chipping, chatter, burning or drill-to-route offset mismatch

Accepted Answer

Routing on supported panel materials; drill comparisons only with the fitted V10 block. 1 · Verify material and tool suitability — A worn, damaged, incorrectly rotating or unsuitable cutter harms finish. — Check the tool maker’s permitted material, rotation and speed. Compression-bit suitability and engagement must be established by the tooling specialist, not inferred from the machine’s maximum RPM. 2 · Check restraint and tool retention — Panel or cutter movement can produce chatter and inaccurate edges. — Resolve vacuum holding and collet/holder problems first. Do not compensate for instability by changing only the program geometry. 3 · Review actual feed, spindle rate and depth per pass — An unsuitable cutting load or rate override can cause chipping, heat or overload. — Compare programmed and displayed rates using the approved process record. Maximum travel speed is not cutting feed. No universal deep single-pass MDF recipe is supplied. 4 · Separate drill-block error from routed-edge error — A wrong tool, moving sheet, reference error or block offset can shift dowel holes relative to the edge. — On V10-equipped machines, measure known drilled and routed features from the same datum. A trained technician identifies whether the main spindle, block or individual drill needs correction; no borrowed drilling-machine offset procedure applies. 5 · Verify the corrected process — A changed tool or setting may solve one feature but not the entire nest. — After Service-approved changes, inspect a first piece for edge finish, hole position, size and depth. Record the validated tool and process setup before batch release. Stop for smoke, loose tools, moving panels or severe vibration. The manual’s material descriptions differ: §2.1 restricts use to engineered boards while §3.2 is broader. Obtain manufacturer approval before applying a solid-hardwood process.

Question 14

VFD/servo trip, spindle heat, Z binding or collision recovery

Accepted Answer

NCG2812E/LE fitted drives; code meanings require the exact drive manual. 1 · Preserve evidence and make the machine safe — Overcurrent, abnormal heat, binding or impact can indicate overload or component failure. — Record the full drive/controller alarm and job line, affected axis, tool and cut conditions. Isolate before access and have Service secure any unsupported load; an emergency stop is not full isolation. 2 · Diagnose before restart — Tool load, cooling, lubrication, electrical fault or mechanical damage must be distinguished. — Have Service use the exact drive code definition and inspect the relevant systems. A “ground leak” or short-circuit alarm needs electrical investigation, not a generic reset. After a collision, verify geometry, tooling, safety functions and job position before an approved restart. Stop operation. Electrical insulation, earth-leakage, drive, bearing and post-collision work are trained-technician tasks. Do not reset repeatedly, raise protection limits or release a head/tool to clear the fault.

Question 15

4/5-axis, pod-and-rail or pin-router problem: what can this guide cover?

Accepted Answer

Overview only. The supplied evidence is for the NCG2812E/LE nesting family. 1 · Identify the actual machine configuration — A general router query may refer to equipment not described in these sources. — Record model, controller, axis configuration and fitted head. “Four spindles” in the NCG manual is not proof of four-axis machining; software support for up to eight axes is not proof that eight axes are installed. 2 · Route specialist symptoms to the correct manual and Service — RTCP/TCP drift, pivot calibration, tilted-plane transformation, rotary backlash or head collision require different procedures. — Provide the exact 4/5-axis or pin-router/pod-and-rail service manual before detailed guidance. Preserve alarm, program, tool and collision evidence. Do not apply three-axis offsets or manually unclamp a rotary head as a workaround. No RTCP, B/C-axis, G68.2, brake-release, harmonic-drive or rotary-union repair procedure is authorised by the supplied documents.

Question 16

Periodical maintenance: inspection, cleaning and service intervals

Accepted Answer

NCG2812E/LE operation manual; confirm fitted components and contradictory intervals with Service. Daily / each shift · machine and contact areas — Dust, contaminated holders or a deteriorating safety condition goes unnoticed. — Inspect visible damage and safety condition each shift. Clean guides, screw/rack areas, workbench and suction interfaces after isolation; clean holders with the approved soft-cloth method. §6.2 calls for daily air-system water/oil drainage and a 5–10 minute spindle warm-up; confirm the actual spindle procedure. Each shift / 8 h · axis lubrication — Dry rails, ball screw or rack surfaces indicate inadequate delivery. — §§6.5–6.6 and table 6.11 call for shift lubrication using the machine pump and identify Great Wall 68# for these points. Confirm the commissioned lubricant and delivery system before replenishing; weekly inspection in table 6.12 does not cancel shift lubrication. Weekly / 40 h · inspection round — Spindle, guide, table, lubricator or pump defects remain undetected. — Table 6.12 lists these checks at weekly/40 h intervals. §6.7 specifies weekly FRL care; isolate and depressurise before opening its bowl. Use only the lubricant approved for that air circuit. Drill-box lubrication · interval conflict — The manual gives inconsistent schedules for the optional drilling device. — §6.3 states 2,000 h, while table 6.11 states 40 h and refers to the drill-box sticker. Ask Service to confirm the exact block interval, lubricant and quantity from the installed label. Do not borrow a grease quantity from a different machine. Monthly / 160 h and six-monthly · pump/cabinet — Cooling and electrical deterioration can lead to breakdown. — Table 6.12 gives monthly/160 h pump and cabinet checks. §6.9 specifies monthly fan/cabinet checks and six-monthly electrical-component inspection. Electrical professionals only; no high-pressure air inside the cabinet. Long-interval component work · specialist only — Pump internals and Z screw-bearing seats require component-specific service. — §6.8 describes 2,000 h lubrication and 3,000 h vane inspection for its illustrated pump; §6.4 assigns Z screw-bearing grease replacement at 20,000 h to Nanxing personnel. Verify pump identity first. Do not copy the manual’s running-state pump-greasing passage into an operator procedure. Only qualified personnel perform maintenance. Distinguish routine cleaning from lubrication and internal servicing. The drill-box interval conflict below must be resolved from its label/manufacturer; do not choose a value by assumption.

Question 17

Preventive maintenance, daily workflow and do/don’t checks

Accepted Answer

Shared NCG2812E/LE workflow; loading/labelling steps only when equipped. 1 · DO verify the setup before each job — Wrong material, datum, tool or holding affects the entire nest. — Confirm panel identity/thickness, tool retention, work offsets, vacuum zones and active NC preview. Keep guards in place and verify extraction before machining. Inspect the first piece before releasing the batch. 2 · DO protect extraction and cooling — Dust accumulation impairs holding, finish, cooling and control reliability. — Check connected ducts and accessible filters; clean only by the approved isolated method. The supplied specifications list extraction velocity of 28 m/s, but port arrangements differ by configuration. Have extraction performance verified at the installed machine. 3 · DO preserve jobs and fault history — Uncontrolled changes make recovery and diagnosis unreliable. — Keep approved jobs and separately identified controller/CAM backups using the installed software instructions. Record date, operating hours, maintenance, alarms and last changes. The supplied manual does not establish a complete backup/restore procedure. 4 · DON’T copy unverified ratings or settings — Conflicting specifications can lead to unsafe setup. — Spindle data varies between 9 and 12 kW; table width varies between 1,220 and 1,230 mm. The product text lists Z travel speed as 200 m/min, whereas the manual/specifications list 20 m/min. Do not use the 200 value or mistake 200 mm Z travel for 50 mm panel capacity. Confirm the nameplate and installed configuration. 5 · DON’T bypass protection or resume blindly — A cleared alarm does not prove that the machine and part are safe. — Do not force I/O, disable a curtain, alter a soft limit or release stored-energy mechanisms. Preserve the alarm before reset and obtain Service clearance after damage, repeated trips or a collision. Verify the restart point and workholding before motion. Consult Service before rectification. Trained technician only for internal diagnosis, calibration or adjustments. Isolate and secure stored-energy loads before access; never bypass an interlock.

2 · Check active file and mode	Recent-file selection, wrong station/channel or task status points to another job.	Compare displayed NC path, station, process type and preview with the physical sheet. Channel mode is operator-loaded; automatic mode is task-manager-loaded in the documented interface.
3 · Verify front/back/label associations	The selected process requires supporting files that are absent.	For matching software, inspect the documented Label and Reverse file relationships and process selection. A front-only job does not automatically include reverse machining.
4 · Review code reload and preview	A changed file or offset has not been validated against the new path.	The manual says saved edits can refresh loaded NC code. Stop before editing, preserve the original, inspect the new preview and obtain approved first-piece validation.
5 · Investigate application or connection failure	Controller connection, licence, external exporter or IPC condition needs attention.	Record hardware/firmware and software versions, exact error and recent changes. Use approved removable media. Do not reinstall CAM, change IP settings or restore machine parameters without support.

Sequence to Check	Possible Cause	Possible Solution
1 · Separate geometry from workpiece movement	Vacuum slip, wrong geometry or an incorrect datum can resemble axis error.	Check holding, active program dimensions and one known test piece. Record whether the error repeats in the same direction or varies between runs.
2 · Compare coordinate and homing status	Wrong work coordinate or incomplete referencing displaces the job.	Compare the intended G54–G59 selection with the verified setup record. The manual does not provide a machine-specific homing sensor map or universal reset value; refer a failed home to Service.
3 · Inspect the appropriate drive system	Contamination, lubrication failure, looseness or wear can impair motion.	The supplied specifications confirm X/Y rack-and-pinion and a Z ball screw with servo drive. A technician checks these systems; do not diagnose stepper “lost steps” or adjust backlash compensation by assumption.
4 · Request measured geometry checks	Gantry squareness, spindle perpendicularity and drive repeatability are different issues.	Have Service measure them separately. An oval circle does not uniquely diagnose gantry squareness, and spindle tramming is not the same measurement as X/Y squareness. Do not correct a mechanical fault by arbitrary scaling or offsets.

Sequence to Check	Possible Cause	Possible Solution
1 · Stop if tool retention is doubtful	Bit movement, damaged collet/holder or contamination creates an unsafe cut.	Isolate and wait for the spindle to stop. A trained person checks tool shank, correct collet size, seating and holder condition against the spindle/tooling instructions. Do not use a guessed torque.
2 · Check the measured tool and selected tool number	Wrong tool identity, changed projection or a stale length entry changes depth.	Compare the fitted tool with the active tool number and approved measurement record. Re-measure using the actual tool-setting gauge procedure before a test.
3 · Check the workpiece reference	Material thickness, spoilboard resurfacing or the wrong work offset changes the effective Z zero.	Confirm the physical top surface and program datum. Do not substitute a generic touch-plate thickness formula; the files confirm a gauge but do not provide that calibration method.
4 · Escalate mechanical or interface mismatch	Binding Z motion or mismatched holder instructions require service.	Stop for grinding or uncommanded movement. The operation manual mentions an HSK taper while the product specs identify ISO30. Confirm the fitted spindle before any taper cleaning, lubrication or drawbar maintenance procedure.

Sequence to Check	Possible Cause	Possible Solution
1 · Preserve the stopped tool-change state	Tool, magazine or spindle is not in a confirmed safe position.	Stop operation and note the tool number, pocket and last action. Keep clear; do not repeat tool changes or pull a retained tool by hand.
2 · Check approved air and accessible holder condition	Low air, contamination or a damaged holder may interrupt clamping.	Read the gauge and alarm without opening the mechanism. The spindle must be fully stopped before tool handling. Inspect only under the approved isolated procedure.
3 · Request the exact spindle/ATC recovery procedure	Clamp sensor, drawbar, valve/exhaust or magazine positioning needs diagnosis.	Have Service verify feedback and the installed tool interface. The manual discusses spindle valve/exhaust condition but does not establish a universal clamp-sensor input or manual unclamp recovery. Do not energise a valve or bypass feedback.

Sequence to Check	Possible Cause	Possible Solution
1 · Verify material and tool suitability	A worn, damaged, incorrectly rotating or unsuitable cutter harms finish.	Check the tool maker’s permitted material, rotation and speed. Compression-bit suitability and engagement must be established by the tooling specialist, not inferred from the machine’s maximum RPM.
2 · Check restraint and tool retention	Panel or cutter movement can produce chatter and inaccurate edges.	Resolve vacuum holding and collet/holder problems first. Do not compensate for instability by changing only the program geometry.
3 · Review actual feed, spindle rate and depth per pass	An unsuitable cutting load or rate override can cause chipping, heat or overload.	Compare programmed and displayed rates using the approved process record. Maximum travel speed is not cutting feed. No universal deep single-pass MDF recipe is supplied.
4 · Separate drill-block error from routed-edge error	A wrong tool, moving sheet, reference error or block offset can shift dowel holes relative to the edge.	On V10-equipped machines, measure known drilled and routed features from the same datum. A trained technician identifies whether the main spindle, block or individual drill needs correction; no borrowed drilling-machine offset procedure applies.
5 · Verify the corrected process	A changed tool or setting may solve one feature but not the entire nest.	After Service-approved changes, inspect a first piece for edge finish, hole position, size and depth. Record the validated tool and process setup before batch release.

1 · Preserve evidence and make the machine safe	Overcurrent, abnormal heat, binding or impact can indicate overload or component failure.	Record the full drive/controller alarm and job line, affected axis, tool and cut conditions. Isolate before access and have Service secure any unsupported load; an emergency stop is not full isolation.
2 · Diagnose before restart	Tool load, cooling, lubrication, electrical fault or mechanical damage must be distinguished.	Have Service use the exact drive code definition and inspect the relevant systems. A “ground leak” or short-circuit alarm needs electrical investigation, not a generic reset. After a collision, verify geometry, tooling, safety functions and job position before an approved restart.

Sequence to Check	Possible Cause	Possible Solution
1 · Identify the actual machine configuration	A general router query may refer to equipment not described in these sources.	Record model, controller, axis configuration and fitted head. “Four spindles” in the NCG manual is not proof of four-axis machining; software support for up to eight axes is not proof that eight axes are installed.
2 · Route specialist symptoms to the correct manual and Service	RTCP/TCP drift, pivot calibration, tilted-plane transformation, rotary backlash or head collision require different procedures.	Provide the exact 4/5-axis or pin-router/pod-and-rail service manual before detailed guidance. Preserve alarm, program, tool and collision evidence. Do not apply three-axis offsets or manually unclamp a rotary head as a workaround.

Sequence to Check	Possible Cause	Possible Solution
Daily / each shift · machine and contact areas	Dust, contaminated holders or a deteriorating safety condition goes unnoticed.	Inspect visible damage and safety condition each shift. Clean guides, screw/rack areas, workbench and suction interfaces after isolation; clean holders with the approved soft-cloth method. §6.2 calls for daily air-system water/oil drainage and a 5–10 minute spindle warm-up; confirm the actual spindle procedure.
Each shift / 8 h · axis lubrication	Dry rails, ball screw or rack surfaces indicate inadequate delivery.	§§6.5–6.6 and table 6.11 call for shift lubrication using the machine pump and identify Great Wall 68# for these points. Confirm the commissioned lubricant and delivery system before replenishing; weekly inspection in table 6.12 does not cancel shift lubrication.
Weekly / 40 h · inspection round	Spindle, guide, table, lubricator or pump defects remain undetected.	Table 6.12 lists these checks at weekly/40 h intervals. §6.7 specifies weekly FRL care; isolate and depressurise before opening its bowl. Use only the lubricant approved for that air circuit.
Drill-box lubrication · interval conflict	The manual gives inconsistent schedules for the optional drilling device.	§6.3 states 2,000 h, while table 6.11 states 40 h and refers to the drill-box sticker. Ask Service to confirm the exact block interval, lubricant and quantity from the installed label. Do not borrow a grease quantity from a different machine.
Monthly / 160 h and six-monthly · pump/cabinet	Cooling and electrical deterioration can lead to breakdown.	Table 6.12 gives monthly/160 h pump and cabinet checks. §6.9 specifies monthly fan/cabinet checks and six-monthly electrical-component inspection. Electrical professionals only; no high-pressure air inside the cabinet.
Long-interval component work · specialist only	Pump internals and Z screw-bearing seats require component-specific service.	§6.8 describes 2,000 h lubrication and 3,000 h vane inspection for its illustrated pump; §6.4 assigns Z screw-bearing grease replacement at 20,000 h to Nanxing personnel. Verify pump identity first. Do not copy the manual’s running-state pump-greasing passage into an operator procedure.

Sequence to Check	Possible Cause	Possible Solution
1 · DO verify the setup before each job	Wrong material, datum, tool or holding affects the entire nest.	Confirm panel identity/thickness, tool retention, work offsets, vacuum zones and active NC preview. Keep guards in place and verify extraction before machining. Inspect the first piece before releasing the batch.
2 · DO protect extraction and cooling	Dust accumulation impairs holding, finish, cooling and control reliability.	Check connected ducts and accessible filters; clean only by the approved isolated method. The supplied specifications list extraction velocity of 28 m/s, but port arrangements differ by configuration. Have extraction performance verified at the installed machine.
3 · DO preserve jobs and fault history	Uncontrolled changes make recovery and diagnosis unreliable.	Keep approved jobs and separately identified controller/CAM backups using the installed software instructions. Record date, operating hours, maintenance, alarms and last changes. The supplied manual does not establish a complete backup/restore procedure.
4 · DON’T copy unverified ratings or settings	Conflicting specifications can lead to unsafe setup.	Spindle data varies between 9 and 12 kW; table width varies between 1,220 and 1,230 mm. The product text lists Z travel speed as 200 m/min, whereas the manual/specifications list 20 m/min. Do not use the 200 value or mistake 200 mm Z travel for 50 mm panel capacity. Confirm the nameplate and installed configuration.
5 · DON’T bypass protection or resume blindly	A cleared alarm does not prove that the machine and part are safe.	Do not force I/O, disable a curtain, alter a soft limit or release stored-energy mechanisms. Preserve the alarm before reset and obtain Service clearance after damage, repeated trips or a collision. Verify the restart point and workholding before motion.
