Grinding device for machining

The polishing device for machining comprises a base, through grooves are formed in the two sides of the top of the base, sliding grooves are formed in the front sides and the rear sides of the inner walls of the through grooves, a containing groove is formed in the base, and a supporting block is fixedly connected to the left side of the bottom of the inner wall of the containing groove; a gear motor is fixedly connected to the top of the supporting block, a round rod is fixedly connected to the output end of the gear motor, a bearing is fixedly connected to the bottom of the inner wall of the containing groove, and a round rod is fixedly connected to the top of the bearing. The grinding device solves the problems that when an existing grinding device works, the clamping effect on a machine needs to be improved, if the clamping effect of the machine is not ideal, the machine shakes in the grinding process, and therefore the machine is uneven in the grinding process and inconvenient to use by a user, the grind
