ABSTRACT:
A machine for sharpening saws having alternating precutting teeth and post-cutting teeth of lesser height which reciprocates a grinding wheel to grind first the leading edge of a pre-cutting tooth to a fixed depth, the grinding wheel is then raised to grind the back edge of an adjacent post-cutting tooth and is next lowered to the same depth for grinding the leading edge of the post-cutting tooth and the grinding wheel is finally raised again thereby cutting a lesser amount of the back face of the adjacent pre-cutting tooth. The machine has a first cam actuating mechanism for imparting a fixed length stroke to the grinding wheel and a second cam mechanism coupled to the first mechanism for varying the stroke with adjustments being provided for both mechanisms.
