ADVANTAGES
A.The granite is after a long-term natural aging, the organizational structure is uniform, the expansion
coefficient is small, the internal stress completely disappeared, as a result of which the precision is very high.
B.Good rigidity, high hardness, strong wear resistance.
C.Not afraid of acid and alkali corrosion, will not rust; do not need oiling, easy to maintain, long service life.
D. Will not scratch, will not limited by the constant temperature conditions, and can maintain the measurement precision at room temperature.
E.Will not be magnetized, and can move smoothly while measuring, no tight feeling, free of the affect of moisture, good flatness
