ABSTRACT:
The disclosed fixture has a main clamping piece defining several differently sized smooth bores, the locations and sizes of which are selected to receive and hold different central mounting mechanisms of incompatible cutting tools, with the intended cutting edge on each cutting tool then spaced beyond and clear of the clamping piece. A stop is provided in accurate vertical registry with each bore, allowing the fixture to be secured to a grinder bed and located accurately relative to the grinding wheel, before the cutting tool is mounted thereon and any sharpening begins. Before being tightened down, the cutting tool can be rotated selectively in the fixture to accurately set where the grinding wheel will sharpen the cutting edge, and a second clamping piece then secures the cutting tool rigidly in the fixture. Special mounting pins cooperate respectively with the different cutting tool central mounting mechanisms to hold the different cutting tools relative to its proper fixture bore.
