The magnetic grinding machine uses the force of the magnetic field to transmit to the stainless steel grinding needle, causing the workpiece to undergo high-frequency rotational motion, thereby achieving precise polishing effects such as removing burrs and dirt. Specifically, it utilizes the power of magnetic field jumping to transfer energy to stainless steel needles, grinding needles, or grinding materials. These grinding materials carry the workpiece through high-frequency rotational flow, vibration, and directional rolling under the action of the magnetic field, thereby passing over the surface of the workpiece, including inner holes, inner and outer teeth, surfaces, and concave and convex surfaces, achieving the effects of cleaning, removing oil and impurities, and grinding and polishing.
