The Leitz PMM-C line combines highly accurate 3D metrology performance with well-proven gear measurement capabilities. These coordinate measuring machines (CMMs) 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. 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.

  • Features and benefits

    Closed-Frame Design
    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.

    Moving Table
    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.

    Best Reproducibility 
    High-resolution scales offer the highest reproducibility of measurement results.

    High Stability
    The active pneumatic damping system ensures stable measurement procedures, eliminating the influence of vibrations.
