摘要:
A stop device for processing machine includes an engaging member mounted to a positioning device and has a tapered male mold which extends above the positioning device. A female mold is connected to an underside of the rotatable board and has a recess which is shaped to receive the male mold. A groove is defined in an underside of the female mold and is wide enough to stop cutting fluid from flowing along the female mold and entering the space between the recess of the female mold and the male mold.
