Leitz PMM-C

Ultra-High Precision CMM and Gear Measuring System

Leitz_PMM-C-M
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.
 

Leitz PMM-C Overview

About you
About your company
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.
 
Tactile and Optical Measurements
The Leitz PMM-C can be equipped with different tactile and optical sensors to fulfil a wide variety of measurement tasks.

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. Using a universal interface, a wide variety of sensors are changed fully automatically, guaranteeing a high degree of flexibility.

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-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.

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.

PRECITEC LR
The PRECITEC LR optical sensor is a versatile solution, offering excellent measurement accuracy for demanding surfaces, including transparent, reflective, matte or coated materials. Based upon a large acceptance angle, even steep surfaces can be measured.

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.

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.
