2. Features: High-Precision, no rust, acid and alkali-resistant, no magnetized, no deform, good abrasion resistance etc.
3. Applicable area: These kind of granite parts are produced for Laser Test Machines.
4. We can manufacture the granite machinery parts by customers’ requirements. The largest part can be up to 8000×3000×600mm.
The final inspection is carried out with laser interferometers, autocollimation telescopes and electronic inclination scales of highest precision. According to your specifications, we insert appropriate threaded holes, T-slots or various metal parts into the granite body. We work with a high-strength two-component adhesive specially designed for bonding steel / granite. Below you will find a table with the dimensions and the maximum permissible tightening torques for the standard threaded inserts. The positioning accuracy of the threaded hole is +/-0.1 mm. The inserts are inserted approx. 0.5 - 1 mm below the surface.
