The Leitz PMM-G provides highest accuracy and a highly enhanced throughput for large-size XXL workpieces. These workpieces are used for example in aircraft and aerospace industries or in ship engine constructions. Also the measurement of large gears used in wind turbines is possible. Despite such large measuring strokes, the Leitz PMM-G reaches a precision and performance level, which is usually common with much smaller 3D measuring machines.
With the Leitz PMM-G, the probing frequency, acceleration, maximum speed and scanning performance are significantly enhanced.
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:
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.
