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.

Sensor configurations available

LSP-S2/LSP-S2 Scan+

The LSP-S2 probe head stands for maximum measurement performance, combining high accuracy with fast scanning properties, even when using styli extensions up to 800 mm. The measurement of complex geometries with the tightest tolerances becomes a standard measurement task with this fixed probe head.

HP-O

The HP-O optical sensor captures measuring points on a wide variety of different materials quickly and efficiently. Even shiny and reflective surfaces can be measured reliably with maximum accuracy. The HP-O is used for both single-point probing and continuous scanning tasks.

HP-S-X1H with HH-A-T2.5

Using the HP-S-X1 probe head, fast and precise measurement processes are guaranteed for all probing procedures, from single-point probing to self-centring scanning to variable high-speed scanning. The HP-S-X1H is combined with the HH-A-T2.5 indexing head and makes it easy to access highly complex workpieces. The sensor can also be flexibly used with a maximum extension of 225 mm.

HP-S-X5 HD

The HP-S-X5 HD fixed probe head offers single-point measurement for all standard inspection tasks and variable high-speed scanning for the form and profile measurement of complex geometries such as spur gears, worm gears, turbine blades and worm wheels. With a maximum sensor extension of 800 mm, even elements at a great immersion depth can be measured.

PROFILER R

The PROFILER R enables the CMM to perform roughness measurements. The sensor is adapted to the HP-S-X5 HD or LSP-S2/LSP-S2 Scan+ and automatically integrated into the measurement process using a styli changer rack. Roughness is measured through tactile surface scanning and the measurement values are transferred to the measuring system via Bluetooth.

SENMATION

The SENMATION intelligent sensor automation system allows even the most complex measurement tasks involving different sensors to be carried out using a single CMM.

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.

Rotary Tables - Leitz
Typically coordinate measurement is at its limits when inspecting parts which require multiple probe changes such as very small and complex internal gearing. Learn more about rotary tables here.
