ABSTRACT:
A cage slot grinding machine having a work head whose work spindle is rotationally indexable by an index device and first and second wheel supports which respectively carry first and second grinding wheels for grinding, two at a time, cage slots of a cage member on the work spindle. Each time the indexing of the work spindle is carried out, the first and second wheel supports are moved by respective traverse feed devices in a direction perpendicular to the work spindle axis but in opposite senses so as to extend the first and second grinding wheels respectively into two of the cage slots. The first and second grinding wheels, after being so extended, are infed in a second direction parallel to the work spindle axis but in opposite senses through the movements of the wheel supports by respective infeed devices, during which the work spindle is pivotally oscillated by an oscillating device through a predetermined angular distance. Consequently, edges on one side of all of the cage slots are ground with the first grinding wheel while edges in the other side of all of the cage slots are ground with the second grinding wheel.
