The slider is slidably connected to the guide rod through a through hole, and a grinding head is fixedly connected to the upper end surface of the slider. The end of the piston rod of the automatic reciprocating cylinder is fixedly connected to the right end surface of the slider;

[0006] When grinding existing gears, dust or debris will inevitably appear, but the existing grinding device cannot handle the dust or debris, which will cause pollution to the grinding platform and make subsequent treatment difficult;
