Features and benefits of granite surface plate and platform measuring products:
① Dense granite structure, smooth surface and nice abrasion resistance, low roughness.
② Natural granite by a long-term aging, the interior stress disappeared, material stable, and will not be deformed.
③ Acid, alkali, corrosion resistance, anti-magnetic.
④ No damp rust, using and maintenance are easy. ⑤ Linear expansion coefficient, little affected by temperature;
⑥ Working surface is scratched by the collision, only produces pits, does not produce convexity pattern, glitch, no effect on the measurement accuracy.
The main disadvantage of granite surface plate and platform is: can not stand over impact, knock, high humidity will be deformed, 1% moisture absorption.
