Our CNC repair technicians are experienced in restoring machine components like the A06B-6079-H305 alpha servo amplifier module. These servo amp modules are vital for providing power to the servo motor in FANUC CNC machines. The FANUC servo amplifier module is prone to failure like a variety of other smaller CNC machine components. It is important to repair or exchange a damaged component immediately to prevent system failure to the entire machine. For servo amp module repairs, just ship your component to Tri Star CNC and our experts will repair the part quickly, so you can get your machine up and running faster. We will carefully inspect the servo amplifier module to determine the cause of failure and begin work immediately. For components only needing to be cleaned, a small service fee will be charged instead of the entire repair cost.

Tri Star CNC has a large inventory of servo amplifier modules available. If your A06B-6079-H305 alpha servo amp module is beyond repair, give our FANUC repair technicians a call to exchange it for another compatible component.
