Hunter aid its new OCL430HD rotor lathe greatly improves medium- and heavy-duty service by machining the rotor on the vehicle. Hub-mounted service eliminates the need to disassemble the hub to remove the rotor, saving a tremendous amount of time and effort; it also reduces runout, providing a more precise cut and extending the life of expensive rotors, according to the company.
The lathe includes all of the operational features of Hunter’s popular OCL410 light-vehicle brake lathe, yet adds more robust lathe components to handle larger rotors, the maker noted. With a reinforced cutting arm and rugged tool holders, the OCL430HD resurfaces rotors up to 17.5 in. in diameter and up to 3.5 in. in thickness. A 1.5-HP, 230 VAC motor provides the additional torque required for medium- and heavy-duty trucks, according to the company.
The ServoDrive system enables technicians to vary the spindle speed and rotational torque of the lathe while in operation, allowing the operator to adjust the speed “on the fly” without compromising the final surface finish. ServoDrive also provides the capabilities needed to activate other patented features including computerized compensation and anti-chatter safeguards, Hunter added.
Pro-Comp computerized compensation adjusts for lateral runout with the push of a button and a simple single-point adjustment, allowing the technician to quickly complete the machining of the rotor within OEM specifications.
ACT (Anti-Chatter Technology) minimizes machining problems by virtually eliminating chatter. ACT oscillates the speed of the lathe while machining the rotor to prevent the buildup of vibration that can occur on any fixed-speed lathe, requiring extra time to install chatter-dampening accessories, according to the company.
The lathe trolley provides an extended low-to-high working range required for serving vehicles when a lift rack is not available or practical, Hunter said. A full selection of adaptors and accessories to match OE specifications of medium- and heavy-duty commercial-grade vehicle hubs and rotors is also available.
