The A06B-6058-H251 Servo amp amplifies the command signal sent from the control panel to a level allowing it to move the servo motor. When this unit is malfunctioning, you may experience erratic operation, blown fuses or even smoking. You can't afford to allow your CNC machinery to lie dormant for too long—every minute spent in downtime is dollars lost.

Enter Tri Star CNC Services. No other FANUC service firm does a better job identifying, diagnosing and fixing CNC components quickly and efficiently. We don't outsource any of our labor to any third party distributors or repair services for supplemental aid, driving up your overall price. We do it all ourselves. Our CNC repair professionals identify the FANUC part needing repairs and bring it to our testing facility in McHenry, Illinois to test it on a closed loop. We diagnose and repair the part as soon as possible to limit your downtime and help you continue to bring in revenue.

Tri Star CNC provides a 1 year warranty on more than just parts and labor—we will do a complete assembly and repair on parts we've repaired within the 1 year period. Our FANUC parts specialists can speed up repairs by offering you a new part from our exchange stock and giving you fair credit on your broken part—we can then repair it on our own time and keep it in our own inventory.
