Granite Surface Plate Grinding and Storage Environment Requirements

(I) Main Service Process for Grinding Granite Platforms

1. Identify whether it is manual maintenance. When the flatness of a granite platform exceeds 50 degrees, manual maintenance is not possible and maintenance can only be performed using a CNC lathe. Therefore, when the concavity of the planar surface is less than 50 degrees, manual maintenance can be performed.

2. Before maintenance, use an electronic level to measure the precision deviation of the planar surface of the granite platform to be ground to determine the grinding process and sanding method.

3. Place the granite platform mold on the granite platform to be ground, sprinkle coarse sand and water on the granite platform, and grind finely until the fine side is ground.

4. Check again with an electronic level to determine the level of fine grinding and record each item.

5. Grind with fine sand from side to side.

6. Then measure again with an electronic level to ensure that the granite platform’s flatness exceeds the customer’s requirements. Important note: The application temperature of the granite platform is the same as the grinding temperature.

(II) What are the storage and use environment requirements for marble measuring tools?

Marble measuring tools can be used as reference work platforms, inspection tools, bases, columns, and other equipment accessories. Because marble measuring tools are made from granite, with a hardness exceeding 70 and a uniform, fine texture, they can achieve a precision level of 0 through repeated manual grinding, a level unmatched by other metal-based benchmarks. Due to the proprietary nature of marble tools, specific requirements apply to their use and storage environment.
When using marble measuring tools as benchmarks for inspecting workpieces or molds, the testing platform must be kept in a constant temperature and humidity environment, a requirement set by marble measuring tool manufacturers. When not in use, marble measuring tools do not require constant temperature and humidity, as long as they are kept away from sources of heat or direct sunlight.
Users of marble measuring tools generally do not have many of them. If they are not in use, they do not need to be transported to storage; they can be left in their original location. Because marble measuring tool manufacturers prepare numerous standard and specific marble measuring tools, they are not stored in their original location after each production. Instead, they need to be transported to a location out of direct sunlight.
When marble measuring tools are not in use, both manufacturers and users should avoid stacking heavy objects during storage to prevent collisions with the work surface.
