Leitz PMM-C 600 / 700 / 1000


Ultra high precision Leitz Coordinate Measuring Machines and Gear Checkers.


The PMM-C series of ultra high precision coordinate measuring machines and gear checkers is suitable for the inspection of standard geometries (i.e. cylinder blocks, gear boxes etc.) as well as for the measurement of special geometries of any kind, such as camshafts, worms, screw compressors and many more.

Leitz 3D probe technology with integrated High-Speed-Scanning for fast collection of large point numbers → Coordinate Measuring Machines of the PMM-C series are also capable of form inspection.


Design features of the Leitz PMM-C Infinity:

  • "Closed frame" design with fixed portal and moving table
  • High resolution steel scales by Heidenhain, with automatic temperature compensation
  • Pre-stressed air bearings with electronic gap monitoring
  • Power transmission by re-circulating ball screw drives
  • Main structure made exclusively of granite and cast iron, avoiding aluminium
  • Leitz 3D probe system LSP-S2, suitable for stylus length up to 800mm

Permitted table load for all PMM-C machines: 2000 Kg (PMM-C 8.10.6/12.10.6: 750 Kg; PMM-C Ultra: 1500kg)

Note: The measuring range for example of a PMM-C 12.10.7 is 1200 x 1000 x 700mm.



Measuring machines of the Leitz PMM-C series are also used as gear checkers.

Fast and precise inspection of any kind of gears up to a diameter of 1550mm is possible with those machines. Gear cutting tools such as Hob Cutters, Broaches, Shaper Cutters and Shaving Gears can also be measured.

Leitz PMM-C Gear Checkers provide several advantages compared to a conventional single purpose gear checker:

  • They are much more flexible, as not only gears but any component and any geometry can be measured.
  • Leitz Gear Checkers work without a Rotary Table, i.e. alignment or centering of the gear is not required.
  • Unrivalled throughput by automatically measuring a large number of gears on one pallet.
  • Complete inspection of gears mounted on long shafts of up to 2400mm.
  • Leitz PMM-C Measuring Machines / Gear Checkers measure all datums as specified in the drawing, even in large internal gears.
