GRANITE SURFACE PLATE (As per IS 7327  2003) 
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.

• Grade 00 (Laboratory Grade) as per DIN Standard only
• Grade 0 (Inspection Grade) as per IS 7327 2003
• Grade 1 (Tools Room Grade) as per IS 7327 2003
• Grade 2 (Shop Floor Grade) as per IS 7327 2003
• Grade 3 (Workshop Grade)as per IS 7327  2003
