Granite mechanical component workbench can process T-shaped groove, U-shaped groove, V-shaped groove, dovetail groove, punching, grooving or hole inlaying metal sleeve. The main mineral components of granite workbench stone are pyroxene, plagioclase, a small amount of olivine, biotite and trace magnetite. It has black luster and fine structure. After hundreds of millions of years of aging, it has uniform texture, good stability, high strength and good hardness, and can maintain appropriate accuracy under heavy load. It is used in industrial production and laboratory measurement

technical requirements for granite mechanical component workbench

1, 000 and 00 grade granite mechanical components are not recommended to be equipped with handling handles

2. Dents or corners on non working surfaces are allowed to be repaired

3. Gabbro, diabase and granite with fine grain and dense structure should be used (biotite should be less than 5% and elastic modulus should be greater than 0.6 × 10-4kg/cm2, water absorption rate should be less than 0.25%), and the working surface hardness should be greater than 70hs

4. The Zui maximum allowable value of the surface roughness Ra of the working face is 0.32~0.63um, and the side is 10um

5. See Table 1 for the flatness tolerance of the working face

6. The perpendicularity tolerance of the side to the working face and the perpendicularity tolerance of the two adjacent sides of the granite mechanical component shall comply with grade 12 specified in gb/t1184

7. When using the diagonal method or grid method to check the flatness of the working face, the fluctuation of the air plane should be checked. See Table 2 for the fluctuation of the working face

8. See Table 3 for the concentrated load area, applied rated load and allowable deflection value of the working face *

9. There shall be no sand holes, pores, cracks, slag inclusions, shrinkage porosity, scratches, bumps, rust and other defects that seriously affect the appearance and service performance on the working face

10. If a threaded hole (or groove) is set on the surface of grade 0 and grade 1 granite mechanical components, its position should not be higher than the working face
