Dual brake rotor finishing system

摘要

A brake rotor refinishing system provides simultaneously refinishing of two workpieces that are clamped at opposite ends of a duplex chuck, when the chuck is installed on a machine spindel. The duplex chuck has respectives sets of jaws that are independently driven by separate pinion elements. In the case of disk brake rotors, opposite sides of both workpieces are finished simultaneously. The system also includes a refinishing machine that incorporates the spindle and a machining mechanism having cutting elements for simultaneously refinishing opposite sides of a pair of disk rotors.
