Granite ruler, also known as marble ruler and rock ruler, is made of "Jinan green" stone by mechanical processing and manual fine grinding. It has the advantages of long service life and not easy to deform. It is suitable for inspection, measurement and marking in mechanical processing and parts manufacturing industries

accuracy of granite ruler: grade 000-1. Executive standard: gb4987-85

granite ruler usage:

granite ruler is mainly used for measuring the flatness and straightness of machine tool workbench, guide rail and working surface. It is an ideal datum for the inspection of instruments, tools and mechanical workpieces, and the marble ruler is especially used in the measurement of

features of granite ruler:

1. After long-term aging, granite has uniform structure and texture, small expansion factor, and no internal stress and deformation

2. Good rigidity, good hardness, especially strong coefficient, so the accuracy retention is very good. I don't like the influence of temperature. I have good flatness retention, and I don't have to worry about the deformation of appearance and the change of accuracy due to the change of temperature

3. The granite ruler will not have scratches and magnetic stress. It can move back and forth smoothly during detection, and will not be sluggish and inflexible

4. It is not afraid of acid and alkali erosion, and will not rust. It is also very simple to maintain and maintain, and has a long service life. Each granite ruler is equipped with a weight reduction hole for easy access during use

the working surface of the granite ruler shall not have cracks, shrinkage, scratches, bumps and other defects, otherwise it will affect the accuracy of the granite ruler
