The Leitz PMM-F is a high-accuracy monolithic gantry measuring machine for medium sized workpieces. It achieves high throughput with highest possible accuracy on the shop floor or in the measuring room. The PMM-F is also available with a large measuring volume of up to 9.6 m3. It does not require costly foundations and can therefore be easily moved. Every Leitz PMM-F measuring machine is equipped with an integrated active vibration damping system.
The Leitz LSP-S2 high performance probe head allows High-Speed-Scanning and can handle stylus length of up to 800 mm.

The Leitz PMM-F gear inspection center provides several advantages compared to a conventional single purpose gear testers:

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 3000 mm
All datums are measured as specified in the drawing, even in large internal gears.

LSP-S2 Probe Head

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.
