Common marble platform specification accuracy table
The marble platform is made of high-quality granite. The natural granite has naturally aged for millions of years, and its physical properties are very stable, and it will not have a large precision fluctuation due to normal temperature difference. High-quality granite is mainly of hornblende, plagioclase, etc., and its crystal is dense, structure is stable, texture is uniform, and physical properties are good. The hardness is (the Shore hardness reaches 90 or above), and the compressive strength reaches 200Mpa or above. The granite platform is resistant to acid and alk, corrosion resistant, does not rust, and is non-magnetic.
The precision of the marble platform made by precision machining is very high, and the following table summarizes some used specifications.
Note: The precision in the table is calculated according to the national standard.
The above is the precision of the marble platform of 1 grade, 0, 00 grade and 000 grade in common specifications.
