Surface grinding is a method of machining the flat surface of an object by using a grinding wheel. It is mainly used when parallelism and flatness are required. It is generally used for square objects, and while processing, the object is fixed to the magnetic chuck on the surface grinder. By controlling the upper surface of the magnetic chuck, parallelism and flatness can be machined with an accuracy of several microns. It is also possible to process grooves and steps with an accuracy of a few microns. In addition, steel, aluminum, stainless steel, cemented carbide, ceramic, and glass can also be machined by changing the grinding wheel.
