A grinding bit for regrinding a component of a constant velocity universal joint which contains a grinding tip, an arbor, and means for removably attaching said grinding tip to said arbor. The arbor has a length of from about 2.0 to about 4.3 inches, the grinding tip has a length of from about 0.7 to about 1.9 inches, and the length of the arbor exceeds the length of the grinding tip by at least about 1.0 inch. The grinding has a head portion with a substantially arcuate shape and has a substrate coated with a abrasive material.

Grinding bit having a novel grinding grip

An adaptor for aligning the components of a constant velocity joint is disclosed. This adaptor is comprised of a base, a body attached to said base, a screw shaft disposed within said body, a left slide nut mounted on said screw shaft, a first annular peg mounted on said left slide nut, a right slide nut mounted on said screw shaft, a second annular peg mounted on said right slide nut, and rotatable adjustment means for moving said left slide nut and said right slide nut in opposite directions upon the rotation of said adjustment means.

Alignment adaptor means

A grinding bit for regrinding a component of a constant velocity universal joint is disclosed. The grinding bit is comprised of a grinding tip, an arbor, and means for removably attaching said grinding tip to the arbor. The grinding tip consists essentially of a steel blank coated with abrasive substance. The grinding bit has a length of from about 2.0 to about 4.75 inches.

Grinding bit

A machine for regrinding components of a constant velocity universal joint is disclosed. The machine contains (1) a chuck mechanism and an adaptor for mounting a component in the chuck mechanism, (2) a grinding bit comprised of a grinding tip, an arbor, and means for removably attaching the grinding tip to the arbor, (3) a rotatable support means for supporting the chuck mechanism, (4) a high speed spindle, (5) a means for adjusting the position of the spindle in the Y axis to move the spindle in and out, (6) means for injecting nonaqueous lubricant onto the grinding bit, and (7) means for purifying contaminated nonaqueous lubricant.

System for grinding a workpiece

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.
