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. Very fast and ultra 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
• As an option or addition to the 3D probe head the Leitz Precitec LR Optical White Light Sensor is available.

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.

Leitz Precitec LR Optical White Light Sensor

As an option or addition to the 3D probe head the Leitz Precitec LR Optical White Light Sensor is available. This sensor uses a chromatic confocal measurement method and is ideal for applications in the area of lenses (glass, plastics), surfaces and profiles.
