Inspection and Measurement Granite Plate Product Description


Our granite surface plate refers to the advanced standards of the leading countries, and its flatness tolerance is in accordance with the JB/T 7975-1999 Surface Plate:

 

Grade 000 =1x(1+d/1000)/μm

Grade  00  =2x(1+d/1000)/μm  

Grade   0    =4x(1+d/1000)/μm  

Grade   1    =8x(1+d/1000)/μm  

(d is the length of the diagonal)

 

 

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 rough edges which might   influence its  measuring precision.

5  Non magnetization.

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