Release time:
2020-10-29
The marble square box is made of Jinan green, granite with black luster, precise structure, uniform texture, good stability, high strength and high hardness. The working surface adopts scraping or precision grinding process to measure the straightness and verticality of the workpiece and equipment installation.
The marble square box is used to detect the flatness and verticality of parts, workpieces, machine tool worktables, guide rails and precision work. It has the advantages of high precision, no rust, acid and alkali resistance, no magnetization, no change, good wear resistance, etc. It can remain stable under heavy load and general temperature.
The marble box is a precision reference measuring tool made of natural stone material. The granite material selected by strict physical test and selection has fine crystal and hard texture. It is an ideal reference plane for the inspection of instruments, precision tools and mechanical parts. The marble square box is superior to the precision measurement reference parts made of high-quality cast iron and steel, and can obtain high and stable accuracy. Even if it is bumped by heavy objects during use, at most a few grains of ballast will be dropped.
