Fanuc CNC Repair

Independent Shops for Fanuc CNC Repair

This directory lists independent repair shops for Fanuc controls, amplifiers, and motors and gives each major component its own page. Each listing shows the shop’s Fanuc repair categories and the shop’s published turnaround and warranty terms. Plant engineers and maintenance teams can compare listings on this page and contact a shop directly through its listing.

Independent repair shops work on Fanuc electronics at the component level and rebuild Fanuc servo and spindle motors. Component-level amplifier repair replaces failed IGBTs, gate drivers, and power supply capacitors in place of a full module swap. A motor rebuild can replace the bearings and the encoder, rewind the stator, and balance the shaft ahead of a load test.

Fanuc Repair by Component

This directory splits Fanuc repair into six component pages for spindles, controls, drives, servo motors, power supplies, and ball screws. Each page explains the common failures for one component and the repair steps published by repair shops and industry sources. The shop list on each page narrows the directory down to shops listed for that component.

Fanuc shows amplifier alarms on the CNC screen and on the LED display of the module in the electrical cabinet. Matching the two readings narrows a fault down to one component ahead of any repair shipment and saves a wasted trip for a good part. A spindle overcurrent alarm still calls for a closer look and can trace back to a failed IGBT in the spindle amplifier or to seized bearings in the spindle motor.

Repair, Spare, or Replace

Some repair shops start with an evaluation of the failed unit and quote the repair ahead of any work on the bench. Certain shops publish a free evaluation and a no-fix, no-fee policy in their terms. Shops can suggest replacement sourcing options for a unit beyond repair.

Legacy Fanuc control boards went out of production years ago and now come from a secondary market with a smaller supply every year. Repair specialists recommend tested and repaired spares from a repair shop over untested salvage pulls from the used market. Spare servo and spindle amplifiers belong in the same inventory plan as the spare control boards for the same machine.

Back Up the Control Ahead of Any Repair

Fanuc controls keep parameters, PMC ladder logic, tool offsets, pitch error compensation data, and part programs in battery-backed SRAM. A dead battery or a damaged SRAM chip can erase that data and leave the machine with no setup to run on. A full backup to a memory card or PC belongs on the checklist ahead of any board removal or battery change.

Battery power on the SRAM during a board repair does not protect data on a chip damaged by the original failure. Repair specialists recommend a parameter backup from the machine ahead of shipping any board for this reason. A printed copy of the parameters and a second copy of the backup at another location give the maintenance team a fallback.

Using This Directory

Listing details come from information published by each shop or sent in by the shop owner. Shop owners can request a new listing or send a correction to an existing listing through the forms on this site. Each listing links to the shop’s own website and phone number for quotes and shipping instructions.

CNC Machine Pros does not perform repairs and takes no part in the quote, repair, or warranty between a shop and its customer. Each shop sets its own prices, turnaround, and warranty terms and handles its own repair work. Questions about a quote, a repair, or a warranty claim go straight to the shop handling the repair.
