Abstract
A grinding machine for automatically cutting gashes into the end of a fluted end mill blank includes a base on which a grinding wheel is supported such that it moves back and forth tracing a swing path. The end mill blank is held in a work head that is supported upon a vertical slide which is in turn mounted upon a horizontal slide that moves over the base. The work head pivots about two axes for positioning the end mill blank at the proper angle with respect to the grinding wheel. A feed assembly advances the horizontal slide incrementally, and at the same time moves a control slide that actuates various switches which control the operation of the machine. The feed assembly also shifts the vertical slide at the proper time within the grind cycle. In addition the machine has a wheel dresser which automatically dresses the grinding wheel when the feed assembly shifts from a rough feed to a fine feed.
