Marble platform maintenance steps

Marble platform maintenance steps:

1 Detect the accuracy of marble platform and determine its current error

2. Rough grind the marble platform with grinding sand and grinding tools to meet the leveling requirements of the benchmark

3. The second and half fine grinding of the rough ground marble platform is to remove the deep scratches, so that the marble platform can reach the standard flatness

4. Fine grind the marble platform working surface to achieve the desired accuracy

5. Test the precision of the marble platform after fine grinding, and then test the precision of the marble platform again after placing it for a period of time

note: the production and maintenance of marble platform need to be carried out in a constant temperature room. Marble platform with appropriate accuracy also has requirements for indoor humidity. Generally, the temperature is required to be 20 ± 2 ° and the humidity is 35%
