Abstract: A grinding process and wheel (2) are disclosed wherein any or all surfaces of a cutting blade (12) may be generated in a continuous grinding operation utilizing a single grinding wheel having a simple profile (4). A grinding wheel (2) having a grinding profile (4) comprising an inner conical surface (6) and an adjacent outer narrow substantially flat surface (8) is provided. The inner conical surface (6) rough grinds to generate a roughed blade surface and the adjacent outer narrow substantially flat surface (8) finish grinds the roughed surface to generate a finished blade surface. Computer numerical control (CNC) is utilized to control the relative movement of the grinding wheel (2) and cutting blade (12) along or about a plurality of axes. Inner (13) and outer (15) arcuate grinding surfaces may also be provided for rough grinding.
