ABSTRACT:
Metal discs such as brake disc rotors have their planar surfaces finished to the correct thickness and polish, within fine tolerances, in a single operation, by rotating the disc in a plane about an axis of rotation passing through its center, applying to its opposed planar surfaces a pair of cutting or machining tools, directly opposed to one another and one on each surface, moving the pair of tools, at a predetermined separation, radially inwardly towards the axis of rotation, and then increasing their separation and returning them to their starting position, ready for operation upon another disc. Such a process finishes brake disc rotors to the required polish and tolerance in a single step, rapidly and efficiently. Limit switches and appropriate power means are provided to stop the radially inward movement of the cutters and separate them, when the desired inner position has been reached and machined.
