Abstract
A tool sharpener especially designed for sharpening drill bits is provided. The tool sharpener includes a grinding wheel subassembly, a tool holder subassembly, such as a drill chuck, an infeed stage subassembly, a cross feed stage subassembly, and a processor which is capable of controlling each of the subassemblies, and moving the subassemblies relative to the grinding wheel, in preprogrammed routines, to effect the sharpening of a tool such as a drill bit.
Claims11
A tool sharpener comprising:
- a grinding wheel subassembly comprising a grinding wheel;
- a tool holder subassembly adapted to retain a tool to be sharpened;
- an infeed stage subassembly operatively coupled to said tool holder subassembly and adapted to move said tool holder subassembly in a direction toward and away from said grinding wheel subassembly;
- a cross-feed subassembly operatively coupled to said grinding wheel subassembly and adapted to move said grinding wheel assembly laterally relative to a tool to be sharpened;
- and
- a processor operatively coupled to said grinding wheel subassembly, said tool holder subassembly, said infeed stage subassembly and said cross-feed subassembly, and adapted to control operation of each of said subassemblies.
