ABSTRACT:
A grinding process and wheel are disclosed wherein any or all surfaces of a cutting blade may be generated in a continuous grinding operation utilizing a single grinding wheel having a simple profile. A grinding wheel having a grinding profile comprising an inner conical surface and an adjacent outer narrow substantially flat surface is provided. The inner conical surface rough grinds to generate a roughed blade surface and the adjacent outer narrow substantially flat surface 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 and cutting blade along or about a plurality of axes. Inner and outer arcuate grinding surfaces may also be provided for rough grinding.
