Granite Surface Plates
Brand : CHOTEN
---------------------------------------
A crystallin rock, has a fine grained, nonporous texture. It is crystallin throughout and the composition is hard and compact. Granite does not have the soft in-between spaces and has therefore a much higher wear resistance plus a higher degree of flatness accuracy.

The material strength of Surface Plate is three times greater than that of ordinary granite and is super rigid. This Surface Plate has a very low expansion coefficient (5 x 10-6 meter per degree), which makes it least responsive to temperature changes.

100 per cent corrosion-proof and acid resistant. Non-magnetic and easy to clean. No oiling required which is mandatory on cast iron surface plate and with non-glaring satin finish.


These plates are inspected through Electronic level Processing System of M/s. Wyler, Switzerland, to ensure the accuracy and flatness.

Plates are supplied with a calibration certificate traceable to National Standards showing graphic display of the fastness. The plates are manufactured by high precision lapping method providing 450 champering at edges & corners to avoid chip off and cracks.
