Product Description
High Precision Granite Surface Plate Overview
Our 800x500mm black granite surface plates provide exceptional stability and accuracy for industrial measurement and inspection applications. These precision calibration tools maintain dimensional stability across temperature variations while offering superior wear resistance.
Material Advantages
Black granite contains high quartz content for maximum hardness and durability. With approximately half the thermal expansion coefficient of iron and one-third the weight, granite plates offer superior handling and temperature stability compared to metal alternatives.
Key Performance Benefits
- Non-reflective surface for accurate visual inspection
- Chemical and corrosion resistant for long service life
- Low thermal expansion maintains accuracy across temperature changes
- Natural rigidity and exceptional wear resistance
- Surface plane integrity maintained even when scratched
- Non-rusting and non-magnetic properties
- Easy cleaning and maintenance requirements
- On-site calibration and resurfacing capabilities
- Suitable for drilling and threaded support inserts
- High vibration damping for stable measurements
