I. Working Principle of Magnetic Grinder Magnetic Field Generation: After starting the magnetic grinder, the magnetic device will generate a strong magnetic field. This magnetic field can be adjusted through the control system to adapt to different workpieces and grinding requirements. Grinding media movement: Under the action of the strong magnetic field, the grinding media (such as stainless steel needles) will be magnetically attracted and move up quickly. These media form complex rotating and tumbling motions in the magnetic field, thus generating relative motion with the surface of the workpiece. Friction grinding: The workpiece is fixed in a grinding tank or on a workpiece clamping device, and the grinding media are in constant contact with the surface of the workpiece at high speeds. Due to their small size and high frequency of movement, the grinding media are able to enter into small crevices and complexly shaped areas of the workpiece surface and carry out all-round friction and grinding. Deburring and polishing: Through the multi-angle, high-frequency contact and friction of the grinding media, the burrs, oxidized layer and tiny unevenness on the surface of the workpiece are gradually removed, and the surface becomes smooth and flat. Second, the advantages of magnetic lapping machine High efficiency: magnetic lapping machine can handle multiple workpieces at the same time, which greatly improves the production efficiency. Uniformity: Due to the complex movement of the grinding media in the magnetic field, the surface of the workpiece can be evenly ground. Environmental protection: compared with the traditional grinding method, magnetic grinding machine reduces the use of chemicals and water, more environmentally friendly. Flexibility: By adjusting the magnetic field strength and grinding time and other parameters, it can be adapted to different workpieces and grinding requirements. Third, application fields magnetic grinder is widely used in many industries such as aviation, automobile, electronics, medical and so on. In the field of aviation, it can be used to deal with precision parts; in the field of automobile, it can be used for surface treatment of automobile parts; in the field of electronics, it can be used for grinding and polishing of electronic components.
To sum up, the principle of magnetic grinder grinding is to use magnetic field to drive the grinding medium to carry out high-speed rotation and tumbling movement, and to remove burrs, oxidized layer and tiny uneven part of the surface of the workpiece through friction and grinding, so as to achieve the purpose of improving the surface finish of the workpiece.
