Highlights of the KNM system
This machine combines proven technologies with new design features and is perfectly adapted to customer needs.
  • Machine structure with outstanding intrinsic accuracy
  • Large bearing distances of guides
  • Drive system close to centre of gravity
  • Machine base on active vibration dampers
  • High precision air bearing rotary table with torque motor
  • Perfectly combines all characteristics of a CMM with the advantages of a roundness/gear measuring system Cost effective combination measuring machine - Gear and 3D - ( Hybrid)
  • Manually movable tailstock, so all shafts can be clamped and measured between centres.
  • Superior high dynamics and precision
  • High end measuring of gears and cylindrical work pieces
  • Numerous additional measuring possibilities
  • Optimized regarding thermal influences
  • Unbeatable price-performance ratio
  • Software is PTB certified & it is a unique feature for customers
