Granite square box

The material of the granite square box is Jinan blue. Granite has a black luster, uniform structural texture, good stability, and high strength. The working surface adopts scraping or grinding technology, which is used to measure the straightness and perpendicularity of the workpiece and equipment installation.

The granite square box is made of Jinan blue, with a black luster, uniform structural texture, good stability, and high strength. The working surface is scraped or ground to measure the straightness and perpendicularity of the workpiece and equipment installation.

Granite square box: flatness and verticality of machine tool worktable, guide rail, and work.

Characteristics of Granite Square Box:

The granite square box has a low roughness value, while the marble, after long-term aging, loses its internal stress, making the material stable and not deformed. Due to the magnetic reaction of non-metallic materials in marble, there is no plastic deformation.

Granite square boxes have advantages such as non rusting, non magnetization, and good stability under heavy loads and general temperatures.

Granite square box is a benchmark measuring tool made of stone materials. After rigorous physical testing and selection of granite materials, the crystals are fine and the texture is hard. It is an ideal benchmark for the inspection of instruments, tools, and mechanical parts. Marble square boxes are superior to measuring reference parts made of cast iron and steel, and can achieve high and stable accuracy. Even if they are bumped by heavy objects during use, at most a few stones will fall off. It will not affect the accuracy of use.

The granite square box is made of "Jinan Green" stone material through mechanical processing and manual precision grinding. Black luster, structure, uniform texture, good stability, high strength, granite square box can withstand heavy loads and general temperatures, and has advantages such as non rusting, abrasion resistance, non magnetization, and non deformation.

The granite material selected through rigorous physical testing is finely crystallized and has a hard texture. Due to its non-metallic nature, granite exhibits magnetic reactivity and no plastic deformation. Therefore, it has good accuracy retention.
