      Specially selected natural granite.
      • Free of flaws, homogeneous structure.
      • Deflection and torsion resistant.
      • Absolutely rustproof and resistant to acid, low thermal conductivity.
      • Micro-fine surface treatment (diamond lapped). Tolerances tighter than recommended limits.
      • Ground outside edges, visually true.
      • For static determination of position, 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.


      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.
