| Material | Black Granite |
| Precision Grade | 000.00.0.1 |
| Standard | JB/T 7975-1999 |
| Function | Precision Measurement |
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
Bran granite surface plate accuracy
refer advanced leading countries
standard.flatness tolerance as follows:
grade 000 1X(1+d/1000)um
grade 00 2x(1+d/1000)um
grade 14x(1+d/1000)um
grade 1 8x(1+d/1000)um
(d is the length of the plate's diagonal)
