SPINDLE AMP AC SP-1S, 1.5S, 2S A06B-6059-H002

Tri Star CNC FANUC repair technicians perform quick repairs of the A06B-6059-H002 spindle amplifier. Spindle amp malfunctions put your production at a standstill. The more downtime, the more dollars lost. Tri Star eliminates downtime by swiftly repairing your A06B-6059-H002 spindle amplifier and returning it to you to get you back online.

The spindle amp helps to maintain consistent speed and torque, and is essential to accuracy and finish quality. It controls high speed AC motors used in machine tool spindle drive applications. Using digital signals, it constantly monitors and adjusts speed, torque and current. When its effectiveness is compromised, the product suffers, and it needs to be cleaned or repaired.

When you work with Tri Star CNC spindle amp repair technicians, you are offered several different options for replacing your malfunctioning spindle amp. Send your malfunctioning component to us and we'll test it on a closed loop system at our CNC repair shop in McHenry, Illinois, returning it to you as soon as its operation is flawless once again. You may purchase a fully refurbished unit from our exchange stock, and you will receive a credit for your malfunctioning unit (which is applied towards the cost of the refurb). Or, if the item is in stock, we send you a brand new OEM replacement part.

We back up our promise of defect-free repair with a 1-year comprehensive warranty covering the entire spindle amplifier—not only the parts we repaired or replaced. If the spindle amp malfunctions within 1 year of our services, we will perform a complete assembly repair.
