ABSTRACT:
A profile grinding machine for grinding the contour surface of an article to be ground such as a wrist watch case or the like is disclosed. The machine comprises a work shaft provided at its one end with a chuck for supporting the wrist watch case to be engaged with a grinder and a profile cam shaft provided at its one end with a profiling cam to be engaged with a profiling cam follower and at another end with a head swing control cam engaged with a cam follower roller. Both the work shaft and the profile cam shaft are rotatably supported by a head swing supporting shaft provided on a profile slide and driven in synchronism with each other. The profile slide is biased in a direction toward the profiling cam follower so as to urge the profiling cam against the profiling cam follower.
