1. The surface hardness of the marble plate is easy to wear when it is low. In this case many operators are easy to overlook.
2. The effect of workpiece material and workpiece surface quality. When the workpiece is cast iron, the wear of cast iron plate is larger, while the workpiece is copper, aluminum and other soft metal, the wear is small, the surface roughness of the workpiece easily scratched the surface of the cast iron plate.
3. The work place is not clean, besides will cause the inspection platform accuracy error, also will increase the marble plate attrition.
4. Workpiece measuring force over the assembly caused by the deformation of the marble plate or earlier wear, once the wear is serious, it is easy to lead to the measurement of data deviation, is very detrimental to the final accurate data obtained.
5. The improper use of marble slabs, such as the use of flat plate test surface roughness of the workpiece will cause rapid wear and so on.
