Hunter’s new ACT (Anti-Chatter Technology) equipped OCL400 On-Car Brake Lathe virtually eliminates the buildup of vibration (chatter) that can occur when machining rotors at a fixed speed. The ACT feature oscillates the machining speed of the lathe during the cut. The result is a smoother finish that prevents pedal pulsation – the number one cause of brake service customer “comebacks.”

Hunter is the first automotive brake lathe manufacturer to employ turning speed oscillation. The ACT feature is now available on Hunter OCL400 On-Car Lathes and as an upgrade option.

The OCL400’s unique ServoDrive system provides the variable speed capability needed to activate the ACT feature. With the ServoDrive system, technicians can resurface rotors at the fastest speed capable and can change speeds during machining. The final surface finish is unchanged, even when the speed is adjusted "on the fly."
