KNM C series

ultra precise universal measuring machines

machine concept
With KNM C series, KAPP NILES Metrology GmbH - manufacturer of the currently largest gear measuring machines (stationary or transportable) in the world - offers a universal high-precision measuring equipment for max. diameters from 500 mm to 1,600 mm. The ultimate form measurement is best suited for medium and large components.

The device is a new development based on well-proven technologies, as well as innovations and has been perfectly adjusted to customer requirements specifically for the determination of form deviations of bearing rings, race rings and all kind of cylindrical workpieces.

Its setup as CNC-controlled 4-axis measuring equipment permits expansion to a larger range of parts as well, including external and internal gears or 3Dmeasuring tasks on prismatic workpieces. Proven software for fully automatic measuring cycles is available.

features:

  • highly accurate mechanics in special design with perfect accessibility
  • base plate, side parts and axes of dark granite lead to consistent thermal conduct
  • base plate supported on controlled air springs for vibration insulation
  • air bearing guide elements in all axes for wearfree and smooth operation
  • generously sized guide cross-sections
  • large distances between bearing positions
  • Y-guide risen, drive close to the center of gravity, low dynamic distortions
  • use of state-of-the-art drive technology (linear motors)
  • rotary table with air bearing and direct drive
  • integrated tailstock (optional)
  • perfect combination between the metrological features of a form measuring device with the strengths of a gear measuring machine respectively coordinate measuring equipment
  • measuring uncertainty (DIN EN ISO10360):

    MPEE ≥ 0.6 + L/400
    MPETHP ≥ 0.8
