Organizational Structures Granite Measuring Table

Granite is applicable to the works of industrial production and laboratory measurement.

- For high precision operations in temperature controlled gauging rooms and metrology departments

- For general quality control use

- For shop work and production checking



Salient Features:


SURFACE PLATES are made of black granite which is stronger and denser than light colored granite, more stable, and wears longer.

The granite properties determine the stiffness of the granite and accuracies can be guaranteed with less thickness than other types of granite.

- This translates to less freight and handling whenever the plate is shipped or moved.

- 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.



Specification:


The precision of the granite surface plates is in line with the standards of advanced countries.
Tolerance of planeness: Standard JB/T7975-1999
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°C )
