The main mineral ingredients of granite are pyroxene, anorthose, less olivine, black mica and less magnetite. Aging through hundreds of millions years, the granite can still retain even character, stable, high strength and hardness, and can keep high precision at heave duty. It is suitable for industrial production and measuring works at laboratory.

1. Hardest uniformity of all granite surface plate
2. Lowest temperature coefficient, least responsive to temperature changes.
3. Moisture and corrosion free, no rusting, no oiling, will not stain or discolor.

4. Practically maintenance free, fast easy to clean.
5. SmoothBall-Bearing?surface.
6. Resists dust and abrasives,
7. Non-magnetic.

Precision has 000. 00, 0, 1 grade.

It is the ideal tool for drawing line and inspection at precision processing company.

Grade 000 =1x(1+d/1000)/μm

Grade 00 =2x(1+d/1000)/μm

Grade 0 =4x(1+d/1000)/μm

Grade 1 =8x(1+d/1000)/μm
