OEM Factory for Assembly& Calibration& Inspection – CNC Granite Assembly – ZHONGHUI

This custom granite assembly is for CNC Machines. This structure is made by black granite according to cusomer’s drawings with operation precision: 0.005mm.

With the continuous development of science and technology, stone application has been brought into a new field, and it has a wider application. With a tolerance of 1 μm, granite easily meets the flatness requirements according to DIN standard for the degree of accuracy 00.

We can produce various kinds of custom Granite Components made out of granite such as base ,column,beam and guide rails ,with a Maximum monomer size of 12000x4500x600mm. More larger size products can be made into splicing. We have made super-long splicing products with a length of 100m. For those big sizes we usually use Jinan Black Granite.
