The Hunter Engineering Co. AutoComp Elite brake lathe has a patented automatic compensation technology directly determines the position of the internal compensation plates without operator intervention. The 7" touchscreen provides a user-friendly interface that allows technicians to look up required adaptors, operate the lathe including changing cutting direction and speed, and view instructional videos. The interface also includes the BitMinder feature which monitors bit life and recommends replacement to improve cut quality and reduce waste. AutoComp Elite also includes patented Anti-Chatter Technology (ACT) which eliminates the buildup of vibration (chatter) that can occur when machining rotors at a fixed speed. This provides the smoothest possible rotor finish without the use of chatter bands or other cumbersome devices, the company says.
