Hub-mounted rotor lathe for medium-duty trucks

Hunter describes its OCL430MD hub-mounted rotor lathe as a solution for shops that service medium-duty trucks and commercial vehicles. The company says the OCL430MD offers all of the speed and productivity features of its OCL400 brake lathe, but includes more robust lathe components to service larger truck rotors.

With a reinforced cutting arm and rugged tool holders, the new lathe is designed to resurface rotors up to 171/2 inches in diameter and up to 31/2 inches in thickness; a 1.5-hp, 230 VAC motor provides the additional torque required for medium-duty truck service. The lathe’s ServoDrive system enables the technician to vary the spindle speed and rotational torque of the lathe while in operation, allowing the technician to adjust speeds “on the fly” without compromising the final surface finish.

The Anti-Chatter Technology (ACT) feature, designed to minimize machining problems by virtually eliminating chatter, oscillates the speed of the lathe while machining the rotor to prevent the buildup of vibration that can occur on any fixed-speed lathe. The Pro-Comp computerized compensation adjusts for lateral runout with a push of a button and a simple single-point adjustment, according to Hunter; after the lathe is mounted to the hub, Pro-Comp compensates the adaptor and lathe to the rotor in seconds, allowing the technician to complete the machining of the rotor within OEM specifications in less than nine minutes.

A trolley for the OCL430MD provides an extended low-to-high working range required for serving vehicles when a lift rack is not available or practical. For more information, go to www.hunter.com.
