Description

Description

Main material composition of granite are picrite, plagoclas, a little olivine, biotite and atom magnetite. It is black and has precision structure. It has uniform texture, good stability, big intension, high hardness and high precision under heavy duty through millions of years aging. It is suitable for the measuring work of industrial production and laboratory.

Flatness Tolerance

The precision of granite surface plate refers to the standard of developed country. The flatness tolerance should accord with the standard of JB/T7975-1999.

Grade 000 = 1 x ( 1+d/1000)µm

Grade 00 = 2 x ( 1+d/1000)µm

Grade 0 = 4 x ( 1+d/1000)µm

Grade 1 = 8 x ( 1+d/1000)µm
