High credit rating, your trusted supplier
Granite rectangular device suitable for the detection of verticality. Plane accuracy of the standard GB6092-85, the vertical standard GB6092-85. To reduce weight and to facilitate the processing and reduction bores. Side of the tolerance is 0.02.
Granite squares is mainly used for the workpiece flatness, perpendicularity, straightness 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.
Precision:according to the national standards measurement examination regulations execution:
|
