NTMT - 630x630mm Granite Surface Table

NTMT Granite Surface Plates are as a precision datum base for Inspection, tool marking, gauging, spotting, marking and layout operations.

MATERIAL:  Granite surface plates are made from selected granites with uniform distribution of light and dark constituents. It has a fine grind, non porous texture and grind size measures less than 1 mm. It has a constant hardness throughout 6 to 6.5 moss scale and 3 times harder than cast iron surface plate. It has very lowest thermal co-efficient of expansion, 100% rust proof and acid resistance, non electric-conductive and easy to clean. Maintenance costs are practically nil. If may chip but cannot develop a burr. 

TECHNICAL DATA:

Granite surface plates are manufactured in 4 grads of accuracy.
