Abstract
A multiple purpose lathe which can include a special valve polishing device, a camshaft lap device and other mechanisms. The valve polishing device includes a pair of generally axially parallel, rotatable rollers positioned to bear against and support a valve stem held therein while being polished by a movable belt. The camshaft lap device includes, optionally, a movable wheel bearing against the polishing belt which, in turn, bears against the camshaft being polished.
