A granite slab is a high-precision reference measuring tool made from natural stone. It serves as an ideal benchmark for the inspection of instruments, precision tools, and mechanical components. Due to its exceptional stability and durability, it's widely used in various industries that require accurate measurements. Understanding how to properly maintain a granite slab is essential to ensure its longevity and performance. Here’s a brief guide on the maintenance and specifications of a granite platform:
1. The working surface of the granite slab must be free from defects such as sand holes, shrinkage cavities, scratches, bumps, pores, cracks, or slag inclusions, as these can negatively impact both appearance and functionality.
2. Minor damage or wear on non-working surfaces, such as dents or chipped corners, may be repaired without affecting the slab’s overall performance.
3. The vertical tolerance of the sides relative to the working surface, as well as the perpendicularity between adjacent sides, should conform to the 12 levels specified in GB/T 1184.
4. The central area of the working surface must be able to withstand the rated load without excessive deflection, ensuring structural integrity under pressure.
5. If threaded holes or grooves are present on the 0th or 1st grade slabs, they should not protrude above the working surface to maintain flatness.
6. When testing the flatness using the diagonal or grid method, it’s important to check the air level fluctuation and the plane variation of the working surface to ensure accuracy.
Proper care and regular inspection can significantly extend the lifespan of your granite slab. Whether you're using it in a laboratory, workshop, or industrial setting, maintaining its quality is crucial for consistent and reliable results.
