01 Product Description
MZ7130 Electromagnetic Full-automatic Knife Grinder
MZ7130 Knife Sharpener is an economical and practical type of knife sharpener with a low failure rate. It is a highly functional and reliable machine.
MZ7130 Knife Grinder is constructed by welding double-layer national standard steel plates and undergoes vibration failure treatment. It is equipped with a powerful electromagnetic suction cup. Place the blade on the worktable and turn on the suction cup switch. The blade will be firmly adsorbed on the worktable. This saves the time of using bolts to press the blade. The blade is ground more smoothly and has a better straight edge.
During the process of installing the blade for grinding, no personnel operation is required. The grinding wheel can be compensated for grinding automatically, saving about 40 minutes of labor.
