Granite Inspection Surface Plate

Granite platform is a platform product made of granite processed by machine tools and manually ground in a constant temperature chamber, with high flatness accuracy.

Physical parameters of granite platform:

Specific gravity: 2970-3070kg/m3;

Compressive strength: 245-254kg/mm2;

Elastic wear: 1.27-1.47N/mm2;

Linear expansion coefficient: 4.6 × 10-6/℃;

Water absorption rate of 0.13;

Shore hardness of HS70 or above.

The accuracy of granite platforms is much higher than that of cast iron platforms. This is because granite has undergone long-term aging treatment and no longer has internal stress. The accuracy levels of 000, 00, 0, and 1 are ideal tools for marking and inspection in processing enterprises.
