Tri Star CNC’s technicians have extensive experience repairing and refurbishing FANUC servo drives and spindle drives. We maintain a well-stocked inventory of parts necessary for overhauling these devices, so you won't have to wait long before we return a working part.

Besides diagnosing and replacing faulty components, we also replace any parts which may be nearing the end of their service life and load test the unit before returning it. We also thoroughly clean all units before sending them back.

The power module cleaning and repair process involves meticulous care and strict attention to detail. We’ll take every step necessary to ensure your FANUC power supply module is entirely clean and functional.

CNC repair technicians at Tri Star clean and bake parts to remove all contaminants. We’ll test power modules on a closed loop system to isolate and identify the source of the problem and perform swift repairs in-house at our facility in McHenry, Illinois.

We offer free over-the-phone support to see if the problem can be solved on site or if repairs or replacement is needed. See all FANUC power supply error codes.
