Granite Surface Plate 

Features

Granite measuring devices and granite mechanical components are made of  high quality Jinan 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 industry and such scientific areas as mechanical aero space and scientific researches.

Advantages

• Twice as hard as cast iron.
• Minimal changes of dimension are due to changes of temperature.
• Free from wringing,so there is not interruption of work.
• Free from burrs or protrusions because of the fine grain structure and insignificant stickness,
  which ensures the high degree of flatness over a long service life and causes no damage to other parts or instruments.
• Trouble-free operation for use with magnetic materials.
• Long life and rust-free,resulting in low maintenance costs.
