Elastic Modulus:120-127Gpa Granite Machine tool components

Specific Grravity 2970-3070kg/m³ Granite Machine tool components

    This  granite machanical part is according to customer's drawings to producted. Has many programs tested.

    Our granite measuring devices and granite mechanical components are made of  high qualityJinan Blackgranite.Due to their high precision,long duration,good stability and corrosion resistance,they have been more and more used in product inspection of modern industy and such scientific areas as mechanicalaerospace and scientific researches.

Granite Property:

1. High precision  reliable stability resistant to deform and guaranteed accuracy under normal ambient temperature.                                                                               Mechanical component

2. No-rust and anticorrosion.

3. Wear resistance long service life.

4  Any cutting or scraching for working surface does not bring about roughedgeswhich might  influence its measuring precision.

5  Non magnetization.

6  Glossy surface  without sluggishness when the workpieces or tools are moving on it.
