DESCRIPTION

Marble side of the organizational structure of dense, smooth surface wear resistance, small roughness value, is made of natural stone material precision measuring tools, through strict physical test and choice of marble stone, crystal, fine, hard texture, the instruments and meters, precision tooling, mechanical parts inspection, all is the ideal datum.

The marble square box has the advantages of high precision, no rust, acid and alkali resistance, no magnetization, no deformation, good wear resistance, and can be stable under heavy load and general temperature.

Marble side of its better than that of high quality cast iron and steel parts, precision measurement datum can obtain high and stable precision, even by a heavy knock against, in use up to drop a few grains of ballast. Through rigorous physical test and selection of the marble, the crystal fine, the texture is hard. All kinds of marble measuring tools are non-metallic materials, no magnetic reaction, no plastic deformation. The hardness is high, so the accuracy is good. In the use of even if the heavy objects knock, at most a few stone.

Side of main mineral elements for marble stone, plagioclase, a small amount of olivine, biotite, and trace magnetite, hard, mohs hardness grade 6 and 7, wear resistance, acid and alkali resistance, corrosion resistance and will not rust, it is mainly used for inspection instrument table, precision tools, machinery parts and other high precision measurement.

The marble square box is in order to ensure the jointing of the board, and the national standard stipulates that the marble plate gauge, the size allowable deviation, the flatness allowable limit tolerance, and the Angle allowable limit tolerance. The marble square box has two kinds of plywood (square or rectangular plate) and special-shaped plate (other shape plate).
