Description
Version:
Specially selected natural granite.
- Free from defects, homogeneous structure.
- Resistant to deflection and to warping.
- Absolutely rustproof and resistant to acids, low thermal conductivity.
- Micro-fine surface treatment (diamond lapped). Tolerances tighter than recommended limits.
- Ground outside edges, visually true.
- For mounting as determined statically, contact points (steel ball inserts) are fitted to the underside.
- Harder than hardened steel (Mohs hardness scale 6 − 7), non-magnetic and electrically non-conductive.
Accuracy:
Final manufacturing and inspection take place in computer-controlled climatic rooms. The used measuring equipment guarantees the exact connection to national and international calibration laboratories.
DIN 876/1 − diamond lapped for workshop and production.
