Abstract
A method and a machine for grinding the components of a constant velocity universal joint of front wheel driven vehicles is disclosed wherein the method involves the grinding of the ball retaining grooves of the outer housing, inner race and outer race elements and the intermediate bearing retainer of the constant velocity universal joint to accommodate oversized replacement ball bearing. The machine is comprised of a rigid base, a component part holder movably supported to the base and moveable about an axis, a tool holder movably supported to the base and movable about at least on axis for accurately positioning a grinding tool within the grooves of the constant velocity joint members. The tool holder comprises a high speed grinding device, incremental adjustment means to accurately position the grooves of the members of the constant velocity universal joint in relationship to the grinding device, a rotatable arm to articulate the axial position of the constant velocity universal joint members and means to automatically control the predetermined patterns of movement of the tool holder according to the size and shape of a variety of contant velocity universal joints.
