Marble square ruler

The characteristics and advantages of marble rulers:

1.Dense organizational structure,smooth surface,and low roughness values;

2.Granite undergoes long-term aging,internal stress disappears,material is stable,and will not deform;

3.Acid,alkali,corrosion,and magnetic resistance;

4.It will not rust due to moisture,and is easy to use and maintain;

5.The coefficient of linear expansion is small and less affected by temperature;

Application of marble square ruler:The marble square ruler is used for frame type combinations with vertical parallelism,suitable for mechanical and instrument inspection,as well as inspection of non verticality between machine tools.It is an important tool used to check the non verticality between various internal components of machine tools.It is the benchmark for measurement.

Installation of marble square ruler:The marble square ruler is placed flat on the testing platform,and a probe is used to pull it from the starting point to the end point on the plane where the square ruler needs to be tested.The range of changes in the probe can be checked to accurately detect the parallelism of the square ruler surface.Our company actually uses a torsion spring comparator with an accuracy level of 0.0005.
