Main Features

  • Cross beam and Axis Z are made of surface-anodized aerometal with superior temperature consistency, reducing the mass of the moving parts and the inertia motion of measuring machine running at high speeds.
  • High-precision self-cleaning air bearing is used for permanently wear-resistant guideways of all the three axes for more steady operation.
  • Patented TESA high-precision optical scale is used for all the three axes.
  • Each motion axes are driven by DC servo motor. Ensure steady and accurate motion.
  • Precise triangular beam patented technology is applied to axis X, featuring lower center of gravity, better mass-rigidity ratio and more reliable motion relative to rectangular and cross beams.
  • Patented pneumatic counterbalance (adjustable) for Z axis combined solves interference between axial movement and transmission system and enhances accuracy and long term stability with flexible suspension system, improves measuring machine’s stability and rigidity.
  • IDC-I control system specially designedy by HEXAGOON for Croma improves the dynamic performance and measuring accuracy
  • Powerful, easy-to-learn and efficient PC-DMIS BASIC (/PC-FMIS PREMIUM) software

  • All aluminium structure combined with hard amodized aerometal for cross beam and Z axis ensures temperature consistency, reduces mass of moving parts and force of inertia, hence ensures high accuracy during high speed movementHigh-precision self-cleaning air bearing in all three axes, smoother movement without wearing down guide ways
  • Europe-imported high-precision optical scales for all the three axes, system resolution up to 0.078um; installation method with one end fixed and the other end freely extensible ensures linear expansion and contraction at temperature change and reduces the deformation of the optical scale.
  • The patented precision triangular beam, featuring gravity center, better stiffness, and more reliable motion compared to rectangular and cross beams.
  • Integral dovetail guideway is Y axis, reduces machine weight as well as twistings during movement, ensures measuring accuracy and stability
  • All axes driven by DC servo motors for stable movement and accurate locations
  • The IDC-I control system specially designed by HEXA or CROMA improves the dynamic performance and measuring accuracy
  • Powerful, easy-to-learn and efficient PC-DMIS BASIC (/PC-DMIS PREMIUM) software

Main features

  • “L” shape movable bridge, with 3 same height columns supporting Y axis groove guideway, while left column, cross beam, carriage and saddle work together as the moving bridge. Better mobility and less abbe error improve CMM’s accuracy and repeatability.
  • X and Z beam adopt the ultra-rigid precise aerometal
  • Y beam adopts precise integrated granite guideway
  • Pneumatic counterbalance (adjustable) for Z axis, together with flexible suspension system, which make Z axis operate stably. This structure is the best solutioin to the interference between axial motion and rive system and improves measuring machine’s stability and rigidity.
  • All machine axes’ transmission mode is timing belt, whose compact, non-skid structure makes it has excellence of high stability and accurate positioning.
  • High-precision self-cleaning air bearing is used for the permanently wear-resistant guideways of all the three axes for more steady operation
  • All machine axes are equipped with the scales (gold and steel) of German Heidenhain which are certified by PTB (Physikalisch-Technische Bundesanstalt), a German national institute of science and technology. Europe-imported high-precision optical scale are used for all the three axes, system resolution up to 0.078um; Installation method with one end fixed and the other end freely extensible reduces the deformation of the optical scale.
  • Remote mounted drive motors reduce moving mass for faster setting, and dissipate heat away from the machine frame
  • Equipped with the powerful measuring software which second to none, Inspector can handle any common shop measurement and inspection tasks
  • Powerful, easy-to-learn and efficient PC-DMIS BASIC (/PC-DMIS PREMIUM) software
