Machining and material advantages of granite components: Granite components are made of stone with no rust, acid and alkali resistance, good wear resistance and long service life, no special maintenance. The granite member is a measurement tool manufactured by utilizing the characteristics of granite for measuring the accuracy of parts in industrial production. Granite components have high precision, good stability and are not easily deformed, which can ensure measurement accuracy. Granite components show black luster, precise structure, uniform texture, good stability, high strength, high hardness, marble components can maintain high precision under heavy load and normal temperature, and have no rust, acid and alkali, wear resistance Sex, non-magnetization, invariant and so on.

　　Granite mechanical components are made of high-quality " Jinan Green" stone by mechanical processing and hand-finishing. Black gloss, precise structure, uniform texture, good stability, high strength, high hardness, high precision under heavy load and normal temperature,  and no rust, acid and alkali resistance, wear resistance, non-magnetization, invariable Etc. The combination of granite components and metal can achieve more perfect results, and has been widely recognized and used by the domestic machinery industry, electronics industry, machine tool accessories industry, and has a good market prospect. Granite components are now widely used in equipment components such as PCB drilling machines, engraving and milling machines, coordinate measuring machines, and binary ternary imaging projectors.
