Product details
Granite square box
: It is a precision reference measuring tool made of natural stone materials. It is used for the inspection of instruments, precision tools and mechanical parts. An ideal reference surface, the granite square box is especially used for high-precision measurements. Granite square boxes are made from high-quality underground rock layers. After hundreds of millions of years of natural aging, their shape is extremely stable. There is no need to worry about deformation due to regular temperature differences.
Granite square box performance:
The granite material that has undergone strict physical testing and selection has fine crystallization and hard texture. Since granite is a non-metallic material, it has no magnetic reaction and no plastic deformation. It has high hardness and therefore good accuracy retention.
Granite square box
Accuracy:
Even if it is bumped by heavy objects during use, at most a few stone particles will fall off. Granite square box is superior to precision measurement reference parts made of high-quality cast iron and steel, and can achieve high and stable accuracy.
Granite square box material:
Its material is Jinan blue. The granite has black luster, precise structure, uniform texture, good stability, high strength and high hardness. The working surface is scraped or precision ground. Cutting process, used to measure the straightness and verticality of workpieces and equipment installation.
Granite square box
Uses:
Testing the flatness and verticality of components, workpieces, machine tool tables, guide rails and precision work. The granite square boxes produced by our company have the advantages of high precision, no rust, acid and alkali resistance, no magnetization, no deformation, and good wear resistance. Can remain stable under heavy load and normal temperature.
