ABSTRACT:
A cam controlled grinding machine in one embodiment of which the spindle is supported for rotation and lateral movement within a nest of three annular rings. Advantageously, roller bearing arrays between the spindle and the first annular ring, the first and second annular ring, and the second and third annular ring permit the spindle and first and second annular rings to rotate relative to one another while the third annular ring is fixed in position. In order to permit lateral movement of the spindle, the centers of each roller bearing array are non-coincident. In a second embodiment the spindle is in effect mounted on an articulated arm having two degrees of freedom. As a result, the spindle can be moved laterally in two dimensions in response to movement imparted to it by the action of a drive follower and cam. In a third embodiment, an annular bearing plate is attached to the spindle and is supported for lateral movement by a plurality of balls contained underneath the bearing plate.
