Granite Surface Plate for Coordinate Measuring Machine

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

Our granite surface plate refers to the advanced standards of the leading countries, and its flatness tolerance is in accordance with the JB/T 7975-1999 Surface Plate:

Grade 000 =1x(1+d/1000)/μm

Grade 00 =2x(1+d/1000)/μm

Grade 0 =4x(1+d/1000)/μm

Grade 1 =8x(1+d/1000)/μm

(d is the length of the diagonal)
