A granite surface plate is an essential investment for laboratories and test facilities. A granite surface plate of 600 x 600 mm can be mounted on a support stand. The stands provide a working height of 34” (0.86m) with five adjustable points for levelling.
For reliable and consistent measurement results, a granite surface plate is crucial. As the surface is a smooth and stable plane, it enables instruments to be carefully manipulated. They are also used in set-up of tooling, production and inspection.
The main advantages of granite surface plates are:
- Non-reflective
- Resistant to chemicals and corrosion
- Low coefficient of expansion compared with cart iron, so less affected by temperature changes
- Naturally rigid and hard-wearing
- The plane of the surface is unaffected if scratched
- Will not rust
- Non-magnetic
- Easy to clean and maintain
- Calibration and resurfacing can be done onsite
- Suitable for drilling for threaded support inserts
- High vibration damping
