Leitz PMM GANTRY - Highest Accuracy
PMM 3D Measuring Machines in Gantry design cover measuring ranges starting at 4000 x 2000 x 1000mm up to 8000 x 3850 x 3700mm.
Despite such large measuring strokes, these machines reach a precision and performance level, which is usually common with much smaller 3D Coordinate Measuring Machines (CMM).
Typical parts measured on Leitz PMM Gantry measuring machines are large diesel engines, jet engine components, aircraft wing structures, columns of printing machines, satellites, large machine tool parts etc.
3D measuring machines of the Leitz PMM Gantry series are also used for gear inspection. Fast and precise inspection of any kind of gears and gear cutting tools up to a diameter of 3750mm is possible with those machines.
In short: Inspection of anything large, but with tight tolerances.
