ABSTRACT:
A conventional cutting tool grinder is fitted with an attachment which imparts translational motion to the cutting tool grinder table in accordance with the pitch of a removable master threaded member. A crank drives a pulley linked to the master threaded member and rotates a translating work piece in accordance with the thread on the master treaded member. Accordingly, a grinding tool can duplicate the thread of a work piece as dictated by the master threaded member. The mechanism of this invention can also be embodied as a separate bench mounted machine incorporating a grinding tool such that it does not require attachment to a conventional cutting tool grinder for its operation.
