Abstract
A method of dressing a wheel using a polycrystalline CVD synthetic diamond dresser, the method comprising: rotating the wheel; and contacting a working surface of the wheel with a working surface of the polycrystalline CVD synthetic diamond dresser, wherein the polycrystalline CVD synthetic diamond dresser is oriented such that a leading edge of the working surface of the polycrystalline CVD synthetic diamond dresser is formed of larger grains than a trailing edge of the working surface of the polycrystalline CVD synthetic diamond dresser.

A method of dressing a wheel using a polycrystalline CVD synthetic diamond dresser, the method comprising:
- rotating the wheel;
- and
- contacting a working surface of the wheel with a working surface of the polycrystalline CVD synthetic diamond dresser,
- wherein the polycrystalline CVD synthetic diamond dresser is oriented such that a leading edge of the working surface of the polycrystalline CVD synthetic diamond dresser is formed of larger grains than a trailing edge of the working surface of the polycrystalline CVD synthetic diamond dresser.
A method of fabricating a polycrystalline CVD synthetic diamond dresser, the method comprising:
- fabricating a free-standing wafer of polycrystalline CVD synthetic diamond material having a nucleation face and a growth face, the growth face comprising larger grains than the nucleation face;
- cutting the free-standing wafer of polycrystalline CVD synthetic diamond material to form a polycrystalline CVD synthetic diamond dresser;
- and marking the polycrystalline CVD synthetic diamond dresser to indicate which side of the polycrystalline CVD synthetic diamond dresser corresponds to the growth face comprising larger grains whereby in use the polycrystalline CVD synthetic diamond dresser can be consistently oriented such that a leading edge of a working surface of the polycrystalline CVD synthetic diamond dresser is formed of larger grains than a trailing edge of the working surface of the polycrystalline CVD synthetic diamond dresser.
