A granite slab is a high-precision reference measuring tool made from natural stone material. It serves as an ideal benchmark for the inspection of instruments, precision tools, and mechanical components. Due to its excellent stability and durability, it is especially suitable for high-precision measurement tasks. With the increasing demand for accuracy in modern manufacturing, the use of granite platforms has become more widespread across various industries. Therefore, it's essential to understand how to properly maintain a granite platform to ensure its long-term performance and reliability. Here are some key maintenance tips:
1. The working surface of the granite slab must be free from defects such as sand holes, shrinkage cavities, scratches, dents, pores, cracks, or slag inclusions, as these can negatively impact both its appearance and functionality.
2. Minor imperfections on non-working surfaces, such as depressions or chipped corners, can be repaired without affecting the overall integrity of the slab.
3. The vertical tolerance of the side of the granite slab relative to the working surface, as well as the perpendicularity between two adjacent sides, should comply with 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 stability under pressure.
5. If threaded holes or grooves are present on the flat surface of 0th or 1st grade slabs, they should not protrude above the working surface.
6. When using the diagonal or grid method to check the flatness of the working surface, it’s important to monitor air level fluctuations and plane variations to ensure consistent accuracy.
Proper care and regular inspection of your granite platform will help maintain its precision and extend its service life.
