Marble platform main mineral components of pyroxene, plagioclase, minor olivine, biotite and traces of magnetite, black gloss, structural precision, marble platform components, after millions of years of aging, even texture, often flat marble platform, stable good strength, high hardness, high accuracy can be maintained under heavy load. Used in industrial production and laboratory measurements. Shenzhen Xiangyu Hardware Machinery to offer standard-foot marble platform are as follows: marble platform is a practical utilization of high-precision testing gauges, from the cutting stereotypes, coarse grind to fine grind into a thermostatic chamber, before and after the high precision (000 = 1 × (1 + d / 1000) um, 00 级 = 2 × (1 + d / 1000) um, 0 级 = 4 × (1 + d / 1000) um, 级 1 = 8 × (1 + d / 1000 ) um, d is the diagonal mm), test the marble platform, suitable temperature (20 ± 2 ℃), accuracy is higher than cast iron platform for instrumentation, precision tools, precision machinery and parts inspection.
