ABSTRACT:
A process and apparatus for grinding the proper taper and all of the flutes with the correct number of spirals simultaneously in a single cycle of the grinding machine. This is accomplished by passing a rotating stock to produce the correct number of spirals under a grinding wheel that is dressed with three or four properly formed ribs depending on how many flutes are being manufactured. These ribs are spaced so as to exactly match the lead distance of the rotating stock during 120.degree. or 90.degree. of revolution, depending on whether a three or four fluted instrument is being manufactured. The height of each individual rib on the grinding wheel varies in relationship with each other to exactly match the correct taper being created by moving either the rotating stock portion of the machine or the grinding wheel portion of the machine so as to increase the distance therebetween.
