Magnetic grinding device and method for tooth surface of bevel gear

The invention relates to a magnetic grinding device for a tooth surface of a bevel gear. The magnetic grinding device comprises a base, a lifting device, a cutter device, a clamp device and a horizontal moving device, wherein the horizontal moving device is arranged on the base; the lifting device is arranged on one side of the horizontal moving device; the clamp device is connected to the horizontal moving device; the cutter device is arranged on the lifting device; the cutter device comprises a honing wheel permanent magnet; and spiral teeth meshed with the bevel gear to be machined are arranged on the honing wheel permanent magnet. The magnetic grinding device is relatively simple in structure and has an obvious machining effect on the bevel gear made of a non-magnetic material; and magnetic grinding is a flexible machining mode, so that the bevel gear can be uniformly machined in all directions at one time, the precision of a workpiece is greatly improved, a cutter changing process is omitted, and the eff
