The Leitz 3D probe technology with integrated High-Speed-Scanning enables fast collection of large point numbers. Coordinate measuring machines of the PMM-C series are also capable of form inspection.

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 1550 mm 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 2400 mm
• Leitz PMM-C coordinate measuring machines / gear checkers measure all datums as specified in the drawing, even in large internal gears.

• 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 800 mm

With horizontal probe extensions of up to 800 mm length the continuous High-Speed-Scanning probe head LSP-S2 allows the measurement of features deep inside a work piece. Its integrated automatic weight balance system can carry styli configurations of up to 1000 g. LSP-S2 is the ideal probe head for long styli.

Probing deflections are measured via high resolution Linear Variable Differential Transducers (LVDT). The LSP-S2 supports all the standard probing modes like Single Point Probing, Self-Centering as well as Continuous High-Speed-Scanning for fast and accurate form and profile measurements.

Like all other Leitz probe heads, the LSP-S2 provides simultaneous and unclamped probing in all axis, always orthogonal to the surface. This allows the correct compensation of any styli deflection.
