DESCRIPTION
The flat granite surface plate is a precision measuring tool made of natural stone material. It is mainly used to inspect the instrument, precision tool, mechanical parts. Its raw material is got from the qualified lithosphere, which has gone through the natural aging for eons of time. That means our product has dimensional stability. Our granite measuring products will not deform because of the conventional temperature difference. If necessary, our granite surface plate can be processed with T-shaped grooves, threaded holes, etc.
PRECISION REQUIREMENT
THE FLATNESS TOLERANCE IS COMPLIANCE WITH THE GB4987-85 STANDARD:
