Abstract: A grinding mechanism includes a track device horizontally arranged in a base, and a slide slidably engaged on the track device. A grinding material is secured on top of the slide and moved in concert with the slide. A gear is rotatably supported in the base and a roller is eccentrically secured to the gear for engaging with the slide. A motor is disposed in the base for rotating the gear. The slide and the grinding material are moved in a reciprocating action along the track device in order to conduct grinding operations.
