High Precision Granite Surface Plate

Product Detail

1. The Description:

 

A high precision granite surface platform (Granite Flat Panel) was a long-term natural aging, organizational structure, uniform, linear expansion coefficient is extremely small, internal stress disappear, not deformed.

granite surface plates are available in three grades. The repeat reading tolerances for each grade are as follows:

 

Grade AA Laboratory - 25 millionths

 

 

Grade A Inspection - 50 millionths

 

 

Grade B Toolroom - 100 millionths

 

All plates have a thickness capable of supporting a total normal load equal to 100 pounds for each square foot of surface plate area loaded in the center of the plate without deflecting the plate along a diagonal more than one-half the flatness tolerance (per Federal Specification GGG-P-463c or DIN 876 STANDARD or GB...).

 

We can manufacture granite surface plate with maximum size 10000*5000*800mm!!!
