[0002] Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties. It has good electrical conductivity, high temperature resistance, acid and alkali corrosion resistance, and easy processing. It is widely used in metallurgy, chemical industry, electrochemistry and other industries. High-purity graphite is used as a neutron moderator in atomic reactors, and can also be used to make crucibles, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, arc lamps, pencil refills, etc. With the development of science and technology, the demand for graphite workpieces in the market is also increasing.

[0003] When processing graphite plate workpieces, milling machines are generally used for precision milling of thickness, but the milling machine is inefficient in processing the thickness of plate workpieces. Therefore, a grinder can be used instead to achieve milling-free thickness processing, thereby improving the efficiency of graphite plate thickness processing. However, its defects are: it is inconvenient to fix and clamp non-metallic plate workpieces such as graphite plates, and the application range for graphite plates of different sizes and shapes is small.
