ABSTRACT:
A disc-shaped grinding wheel has a peripheral grinding edge, and according to one feature of the invention a centered grinding point is used on the grinding wheel for precise and symmetrical sharpening of right and left cutter elements of a saw chain. The chain is supported by a chain holding bar which in turn is supported on a pivot support on the base of the machine. The pivot support provides adjustment of the bar for oblique engagement of the grinding wheel with the cutter elements. The pivot support also provides a tilting adjustment of the chain holding bar for engagement of the grinding wheel with the cutter elements at a secondary angle whereby to sharpen chisel bit chains. The pivot support also allows the machine to sharpen chipper tooth chains.
