The main mineral components of granite include pyroxene, plagioclase, a little olivine, biotie and trace
magnetite. It is precise in structure with black luster and through hundreds of millions years aging, it is of uniform texture, nice stableness, high intensity and rigidity, and can maintain a high precision under heavy weight. So granite is applicable to the works of industrial production and laboratory measurement.
The precision of the Jingda granite surface plates is in line with the standards of advanced countries.
Tolerance of planeness: Standard
Grade 000 = 1 × ( 1+d/1000 ) μm
Grade 00 = 2 × ( 1+d/1000 ) μm
Grade 0 = 4 × ( 1+d/1000 ) μm
Grade 1 = 8 × ( 1+d/1000 ) μm
( "d" is the diagonal mm ) (The measuring temperature is normally 20±2℃ )
All the standard size are in store and the special size or design can be made as your requirement.
