Custom Size Granite Surface Plate Professional Measuring Tool
The granite surface plate is a precision reference measuring tool made of natural granite through mechanical processing and precision grinding. It has the advantages of being rust-proof, acid and alkali resistant, non-magnetic, non-deformable and excellent in wear resistance. Thanks to hundreds of millions of years of natural aging, its internal stress is completely eliminated, resulting in extremely stable shape, and it can maintain high precision under heavy load and normal temperature conditions.
