FEATURES OF GRANITE PRODUCTS

Our granite easuring devices and granite mechanical components are made of highquality "Jinanqing"granite.Due to their high precision,long duration,good stability andcorrosion,they have been widely used in modern industrues and hightechareas such as machinery aerospace and scientific researches.

Phycical Properties of "jinanqing"GraniteRock:

Granite measuring tools have the following characterisics：

（1）High precision,reliable stability,resistant to deform and guaranteed accuracy under normal ambient temperautre.
（2）No-rust and anticorrosion。
（3）Wear resistance,long sercice life.
（4）Any working surface cutting or scratching does not bring about rough"edges"which might influence its measuring precision.
（5）Nonmagnetization.
（6）Gloosy surface without sluggishyness when the workpieces or tools are moving on it.
