Granite Cube Boxes

  Purpose of Moorstone Square Box: It is mainly used for detecting the planeness and the verticality of shaft type parts, accessories and precision mechanical parts of workpieces as well as marking measurement of shaft type parts.

  Moorstone Square Box: It is made of Jinan Qing moorstones which are black, compact in structure, uniform in texture, high in stability, high in strength and high in hardness, the working face is subjected to scraping or precision grinding process, and the moorstone square box can be applied to the measurement of the linearity and the verticality of workpieces and equipment installation.

  Moorstone Square Box: It is a precision norm measurement device made of natural stones and is an ideal datum plane for the measurement of instruments and meters, precision tools and mechanical parts. The moorstone square box is specially used for high-precision measurement. It draws materials from good-quality underground lithospheres, they are naturally aged for hundreds of millions of years, and their state is quite stable, so that you should not worry about the deformation under the ordinary temperature difference. The moorstone square boxes manufactured by our company have the advantages of high precision, no rustiness, acid-alkali resistance, no magnetization, no deformation, high wear resistance, etc. and can keep stable under heavy load and at ordinary temperature.

  Moorstone Square Box: Even if it is bumped by heavy articles during use, only few small stones fall off. Compared with precision measurement norm parts made of good-quality cast iron and steel, the moorstone square box has high and stable precision.
