Granite square box products are mainly used to test the flatness of parts and components. Granite measuring tools are basic instruments suitable for industrial inspection, and are suitable for the inspection of instrument machines, precision tools, mechanical parts and high-precision measurement.

Product features and applications:

1  High precision  reliable stability resistant to deform and guaranteed accuracy under normal ambient temperature.

2  No-rust and anticorrosion.

3  Wear resistance long service life.

4  Any cutting or scraching for working surface does not bring about roughedges which might  influence its measuring precision.

5  Non magnetization.

6  Glossy surface  without sluggishness when the workpieces or tools are moving on it.

Granite square boxes are mainly used to check the flatness of parts, basic instruments for industrial inspection, mechanical parts inspection and measurement of high clarity.

Special specification can be made as your special need.
