Lab facilities

A Klingeinberg P65 Gear Measuring CentreThe UK National Gear Metrology Laboratory (NGML) is exceptionally well equipped to measure gears and related products including:

  • Spur and helical involute gears.
  • Straight and spiral bevel gears.
  • Involute and non-involute worms.
  • Worm wheels.
  • Shaping cutters.
  • Shaving cutters.
  • Hobs.
  • Involute splines.
  • Straight sided serrations.
  • Free form scanned surfaces (such as tooth root radius) and conversion to a CAD format.
  • General co-ordinate measurement by scanning or point measurement.
  • Surface roughness.

The equipment within the laboratory includes:

  • An enhanced Klingelnberg P65 Gear Measuring Centre used as the reference calibration and measurement machine (installed 2003).
  • Höfler EMZ 632 CNC gear measuring machine (installed 1994).
  • Zeiss WMM 850 CMM updated by IMS Ltd (updated 2009).
  • Talyor Hobson Form Talysurf 50E surface roughness and form measuring instrument.
  • Klingelnberg PEW 02 Transmission Error measuring machine.

To maintain the accuracy of these measuring instruments the temperature within the laboratory is controlled to within 20.0°C ± 0.3°C.
