technical field

The utility model relates to the technical field of grinding machines, in particular to a grinding machine.

Background technique

The traditional grinding of materials is manually polished by a grinder. Because the speed of the grinder is high, the operator's operating speed should be fast and uniform to prevent excessive grinding of materials, which requires the operator to have certain experience, and The grinding process can only grind one surface of the material at a time, and the grinding efficiency is relatively low.
