Ultra-High Precision CMM and Gear Measuring System
The Leitz PMM-C combines highly accurate 3D metrology performance with well-proven gear measurement capabilities. This coordinate measuring machine (CMM) can be equipped with tactile probes for maximised scanning accuracy and a variety of optical sensors for non-contact measurements.
Every detail of the Leitz PMM-C series is focused on achieving certainty with accurate information users can trust. Providing durability and measuring consistency, the machine’s closed-frame design is comprised of a solid granite base, a fixed portal with cast iron pedestals and a granite crossbeam.
The Leitz PMM-C line combines ultra-high accuracy with unmatched high machine dynamics. This results in extremely short cycle times and optimised throughput. Fast data collection and advanced high-speed scanning further improve throughput for efficient process control.
With excellent performance due to variable high-speed scanning (VHSS), measurements can be carried out following the principle ‘as fast as possible, as slow as necessary’. The scanning speed is adapted to known geometries in real time, with simple lines being scanned fast and the speed automatically changing when scanning complex passages.
The optional use of the rotary table allows scanning procedures to be carried out with continuous 4-axis scanning, so even highly complex parts can be scanned quickly with a high point density.
Leitz PMM-C series measuring machines can also be used as gear measuring systems, enabling fast and ultra-precise inspection of any kind of gears, up to a diameter of 1 550 mm. Gear cutting tools such as hob cutters, broaches, shaper cutters and shaving gears can be measured easily.
The granite base with a fixed portal of cast iron and a granite crossbeam ensures long-term stability. The high stiffness of the measurement axes is designed to ensure consistent accuracy over the entire measurement volume.
The travelling measuring table on pre-loaded air bearings with centrally-positioned spindle drive ensures constant dimensional relationships and efficient movement sequences with no tilting or twisting.
High-resolution scales offer the highest reproducibility of measurement results.
The active pneumatic damping system ensures stable measurement procedures, eliminating the influence of vibrations.
