  • Inner race grinding machine
    Patent number: 5916013
    Abstract: 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.
