The Leitz PMM-G features the Overhead Design with integrated U-shaped foundation for highest accuracy and high throughput. As a result, all moving masses have been minimized.

The X axis is equipped with dual drive motion systems and transducer systems. The PMM-G features also the Leitz LSP-S2 scanning probing system. This probe head measures very precisely even with long and heavy styli. Styli configurations of up to 800 mm and 1000 g are possible.

Leitz PMM-G gear inspection systems provide several advantages compared to a conventional single purpose gear tester:

• They are much more flexible, as not only gears but any component can be measured.
• Leitz gear inspection systems 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 7000 mm.
• All datums are measured as specified in the drawing, even in large internal gears.

• Moving gantry in overhead design with minimized moving mass
• Massive granite guiding structures in X and Y, on two-point support
• Ceramic Z-ram
• Dual drives and dual scales in X
• Leitz LSP-S2 probe system, suitable for stylus length up to 800 mm
• Integrated pneumatic damping system for machine and foundation

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.
