A grinding machine for grinding an inner race of a constant velocity joint, which contains a grinding wheel with a concentric peripheral surface of boron nitride, and a device for rotating the grinding wheel at a speed of at least about 5,000 revolutions per minute. The machine also has a lubricating fluid injection system for lubricating the inner race and grinding bit. The machine also contains devices for moving the inner race in the X axis, in the Z axis, and simultaneously in the X and Z axes.

Inner race grinding machine

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

A grinding machine for regrinding a housing of a constant velocity joint which contains a grinding bit, a high speed spindle, a lubricating fluid injection system, and devices for rotating the housing, for moving the housing in the X axis, for moving the housing in the Z axis, and for simultaneously moving the housing in the X and Z axes. The fluid injection system has two coolant nozzles with different volumetric flow rates.

Housing grinding machine

A grinding machine for several ball cages. The machine contains a grinding bit, a multiple cage holder in which several cages are disposed so that the centers of the windows of their cages are vertically aligned with each other, a device for moving the multiple cage holder in the Z axis, the X axis, clockwise, and counterclockwise, a lubricating fluid injection system, and a high-speed spindle.
