Ultra-high-accuracy measurements of tight tolerance parts with maximum application adaptability
Would you like to know more?
Leitz PMM-C CMMs are highly precise, premium metrology devices that deliver fast, ultra-high accuracy results to fulfil the most demanding inspection requirements across a range of precision applications.
The latest generation of machines offers exceptional accuracy across the series, with specific configurations and capabilities to serve individual application needs.
Two base models – Precision and Flexibility – address high precision applications with very tight form tolerances and applications that also require a high degree of sensor flexibility.
The Leitz PMM-C Flexibility model is configured to boost the machine’s adaptability to more challenging applications and part features and decrease cycle time. It combines accuracy and flexibility in one measurement solution.
This model has an articulating probe head that measures at any angle to improve access to complex 3D part geometries. In addition, the SENMATION sensor automation system increases measurement flexibility by allowing the seamless integration of a variety of tactile and optical sensors within one measurement routine to address multi-part or multifeatured applications.
Ultra-high accuracy measurement of complex, very low tolerance size and form features with reduced cycle time
- Complex 3D geometries with very tight tolerances
- Multiple parts with different measurement requirements
- Functional size and form features in hard-to-access spatial orientations around the part
- Very tight tolerance features with great immersion depth
- Multiple material types and surface characteristics
Leitz PMM-C Flexibility benefits
- High-throughput and versatile multisensor measurements
- Easy access to complex parts with a motorised indexing probe head
- Extended application adaptability with automatic sensor exchange during a measurement cycle, which transforms the CMM into a multisensor inspection device
- Non-contact measurements with chromatic white light, interferometric and laser scanning sensors
- Simultaneous 4-axis scanning – optical or tactile – in combination with a rotary table
Options tailored to individual application needs
Manufacturers can further tailor the capabilities of each Leitz PMM-C Flexibility machine with options to meet their application needs best. A range of options can be selected during initial CMM configuration or set up later as upgrades to the in‑service machine to meet changing needs. This future-ready modularity equips users for a range of metrology tasks in a broad spectrum of high-precision manufacturing applications, now and in the future.
The Leitz PMM-C Flexibility model can be equipped with additional probe heads and sensors to make it suitable for a larger field of applications:
Fixed scanning probe for measuring complex geometries at the tightest tolerances with high precision and repeatability with high flexibility using heavy and long styli configurations.
HP-OW white light sensor
Highly accurate optical sensor for almost all materials, including the most challenging surface finishes.
HP-O Flex optical sensor
Unrivalled fast and precise measurements for the tightest tolerances using interferometric optical distance measurements.
Surface and roughness sensor for surface evaluations in the same measurement setup.
Accuracy+ reduces the CMM’s volumetric measurement error to the next level of sub-micron accuracy and increases repeatability to address the very tightest part tolerances. The need for such capability is a growing trend in many industries and precision gauge calibration.
For mid and large-size Leitz PMM-C models, Accuracy+ includes an even more accurate Sweet Spot measurement volume. This delivers ultimate accuracy levels when measuring very tight tolerances on smaller parts or features that need to use only a limited area of the potential measurement volume.
Throughput+ achieves up to 20% faster throughput than the standard configuration – best in class in ultra-high accurate CMMs.
The option boosts measurement productivity by significantly increasing the machine’s maximum axis acceleration and measurement speed without compromising accuracy or precision.
Throughput is key to avoiding delays and ensuring parts are shipped on time. High measurement throughput is particularly important for near-line and 100% part inspection.
Ultra-high accurate measurements have historically been confined to high-end measurement rooms. With the Leitz PMM-C, this is no longer true.
The XT (extended temperature) option allows medium and large-size machines to be used near the production line without needing a costly climate room, which is unprecedented for CMMs of this accuracy class.
The option enables accurate and reliable measurement in a precision production environment with an operating temperature range of 18-24°C that meets class 4 measurement room quality specifications.
The Leitz PMM-C Flexibility model can be equipped with various other options to get the most out of the machine for all applications:
A rotary table extends a CMM's capabilities to allow continuous 4-axis scanning procedures. They enable access to workpieces from any angle, so even highly complex parts can be scanned quickly, with fewer probe changes, increasing throughput.
QUINDOS for special geometries
QUINDOS can handle the most complex and challenging metrology projects, making it the go-to solution for regular, freeform, and special geometries, including gears, gear tools, blades, and other intricate applications.
PC-DMIS is available in the CAD++ configuration, with optional modules available to fine-tune the software for specific applications.
Features and benefits
The Leitz PMM-C brings together innovative technologies that make it the pinnacle of high-performance metrology. The outstanding stability of the Leitz PMM-C platform guarantees maximum accuracy and reduced measurement uncertainty across the range. In addition, the latest generation of machines adds functionalities and features to lift the system to the next level of ultra-high accurate dimensional inspection.
The granite base and fixed portal guarantee long-term stability. The high stiffness of the measurement axes ensures consistent accuracy over the entire measurement volume.
An efficient and precise travelling measuring table on pre-loaded air bearings ensures stable dimensional relationships and efficient movement, with no tilting or twisting.
Save air, save energy
Eco Mode+ reduces compressed air consumption, contributing to a more sustainable future. Save up to 100% of compressed air when the machine is idle and reduce overall air consumption during a typical measurement routine.
Automatic sensor exchange
SENMATION makes a CMM a multisensor inspection device capable of completing the most intricate measurement challenges with fully automatic sensor exchange during a measurement cycle.
Know what the CMM is doing. Messaging lights on the machine provide at-a-glance monitoring of the CMM’s operating mode.
High-speed and safety
Monitoring by two 2D laser scanners allows worry-free high-speed measurement in CNC mode. The machine will stop automatically when the user or an object encroaches upon the protected area.
High speed and accuracy
Servo-drives with recirculating ball screws support fast measurement. The CMM accelerates rapidly while retaining positional accuracy, reaching top speeds even over short movement paths.
Sweet spot (option together with Accuracy+)
Achieve ultimate accuracy levels for measurement of very tight tolerances on smaller parts or features that need to use only a limited area of the potential measurement volume.
4-axis scanning (option)
The optional rotary table allows measurement to be carried out with continuous 4-axis scanning, so highly complex parts can be inspected quickly with a high point density.
Wider operating temperature range (option)
The XT (extended temperature) option enables use in precision production environments that meet measurement room quality class 4 specifications – without needing a costly climate room.
