ABSTRACT:
A headstock for a cam grinding machine comprising a headstock housing for housing a work spindle rotatably supported on a rocking table which is urged by means of springs to be pivoted so as to contact master cams carried on the work spindle with a follower roller. The headstock housing is provided with a pair of spaced through bores co-axially extending in parallel relation with the work spindle. A follower support assembly and a wheel support assembly are held in engagement with the bores in the headstock housing in a manner of selective use, so that the follower roller and a master cam grinding wheel are selectively supported with the same support reference, to be rotatable about the axis of the bores.
