Claims
- 1. A device for dressing a grinding wheel having a profiled working surface, said device comprising:a holding fixture for holding a grinding wheel; a rotary truer; a holding fixture for holding said rotary truer; means for rotating said grinding wheel with respect to said rotary truer; and an infeed device that presses together said rotary truer and said grinding wheel; and an infeed device for pressing said rotary truer against said grinding wheel, said rotary truer being a hard metal wheel having a face that is evenly coated with polycrystalline diamond material and into which face is centrally processed a hole, said infeed de4ce being designed for highly accurate ranges of infeed feed pressure between said grinding wheel and said rotary truer, so that bond posts of single abrasive particles of said grinding wheel fracture, and said rotating means rotating said grinding wheel counter to said rotary truer at zero relative surface speed, without slippage.
- 2. The device as recited in claim 1, wherein said hard metal wheel is tapered so that nearly point contact occurs between said hard metal wheel and said grinding wheel to be dressed.
- 3. The device as recited in claim 2, wherein said hard metal wheel is reduced so that nearly point contact occurs between said hard metal wheel and said grinding wheel to be dressed.
