Pairs of supply Granite Vee Blocks

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.

The "TAI GOLD STONE"brand of granite measuring tools have the following characteristics:

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

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.

For inspecting the coaxality cylindricity symmetry and shifting of revolution parts.
