 DIN 000 Granite Measuring instruments Precision granite square 

  High Precision Straigh Edges.DIN000 the surface precision is 2.5_um.

  Our granite measuring devices and granite mechanical components are made of  high qualityJinan Blackgranite.Due to their high precision,long duration,good stability and corrosion resistance,they have been more and more used in product inspection of modern industy and such scientific areas as mechanicalaerospace and scientific researches.                                                

Granite Straight Edges

The "GOLD STONE"brand of granite measuring tools have the following characteristics:

Granite Straight Edges

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

 2  No-rust and anticorrosion.Granite Straight Edges

3  Wear resistance long service life.                                                        

4  Any cutting or scraching for working surface does not bring about roughedgeswhich might  influence its measuring precision.Granite Straight Edges

5  Non magnetization.                                                     

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

Use for high precision measuring.
