Abstract
A fine-grinding machine having a tool engageable with a workpiece is oscillated linearly at high speed has a drive comprising a tool-carrying slide having a connecting pin extending along an output axis, an input shaft centered on and normally rotating about an input axis offset from and generally parallel to the output axis, an eccentric carried on the shaft and having an outer surface eccentric to the input axis, and a link having an input end at the input axis and an output end at the output axis. A roller bearing supports the input link end on the outer surface of the eccentric. An elastomeric sleeve bearing snugly surrounds the connecting pin and snugly fits in the output end of the link.
