Granite Surface Plate Measuring Tool

Rock by long-term natural aging, organizational structure, uniform, linear expansion coefficient is very small, the internal stress completely disappeared, no deformation, so the accuracy is high.

Rigid, high hardness, wear resistance.

Not afraid of acid and alkaline liquid material erosion, and will not rust, do not need oiling, not easy to stick dust, easy maintenance and maintenance, long service life.
Will not scratch, without a constant temperature to prevent ,temperature measurement accuracy can be maintained at room temperature
Not magnetized,measurements can move smoothly,no zhise sense,not by wet impact,plane said will be a good.

1.The largest size for production is 3000mm width and 6000mm length
2.We also accept to make any relative process
