ABSTRACT:
Various embodiments of multiple belt camshaft grinding machines each have grinding belt drive, contouring and support members carried on a feed table for separate control of cam contouring and grinding feed rate while the camshaft workpiece is carried on a fixed axis by a table providing axial motion for belt wear balancing oscillation and, optionally, camshaft indexing. Curved shoe or wheel contouring members allow reverse curve cam grinding. Special shoe materials and belt-shoe lubrication may be provided to reduce shoe wear. Other features are also disclosed.
