Precision Granite Surface Plate [10000mm*5000mm*400mm]
1.The granite is after a long-term natural aging, the organizational structure is uniform, the expansion cofficient is small, the internal stresscompletely disappeared.
2.It is against acid and alkali corrosion, rust resistant; do not need oiling, easy to maintain, long service life
3.Not limited by the constant temperature conditions, and can maintain the high precision at room temperature
4.No magnetization, and can move smoothly while measuring, no tight feeling, free of the affect of moisture, good flatness
