Portable CMM Series Delivers Flexibility and Precision in Dimensional Inspection
To meet the challenges of inspecting complex geometries and large components on the shop floor, PMT introduces its GAMMA Series of Portable CMMs, offering 6-axis and 7-axis configurations, plus a powerful new laser scanner. Together, these technologies are engineered to deliver superior measurement precision, flexibility, and operational efficiency.
Precision Meets Portability
The PMT GAMMA 6-axis portable coordinate measuring machine (CMM) is designed for accuracy-critical inspection tasks in challenging industrial environments. With measurement accuracies up to 0.01 mm, the GAMMA 6-axis series is available in three accuracy grades—P, M, and E—to suit a wide range of applications.
Covering measuring volumes from 1.5 to 4.5 meters, the system is ideal for inspecting workpieces across diverse sectors, including automotive, aerospace, and energy. Compatibility with GH/GS laser scanning heads and an optional 8-axis rotary worktable enhances measurement consistency and operational reliability. Whether on the production floor or in the quality lab, the GAMMA 6-axis series empowers manufacturers to maintain a competitive edge in quality control.
Enhanced 7 Axis Freedom of Movement
Building on the proven performance of the 6-axis model, the GAMMA 7-axis portable arm adds an additional degree of freedom—providing greater reach and flexibility, particularly when navigating complex surfaces or tight inspection zones.
Also available in P, M, and E accuracy grades, the 7-axis arm supports GH/GS scanning heads, an 8-axis rotary table, and even customized configurations tailored to unique inspection needs. Its rapid deployment and intuitive operation make it especially well-suited for real-time, in-process inspections on the shop floor, where speed and repeatability are essential.
Next-Level Scanning
To address the limitations of traditional contact-based metrology, PMT offers its GAMMA Blue Laser Scanner, purpose-built for use with both 7-axis and 8-axis GAMMA arms. With its optimized optical design, the scanner delivers stable, high-accuracy non-contact measurements, even on complex or delicate surfaces.
A standout feature is its eye protection mode, which reduces operator fatigue by allowing users to adjust laser brightness, an important ergonomic advantage for extended scanning sessions. By capturing full-coverage geometry and surface data, the GAMMA scanner removes bottlenecks associated with conventional tactile probing, offering a faster, more complete view of dimensional conformance.
Total Inspection Versatility
The PMT GAMMA portable CMM ecosystem represents a leap forward in metrology versatility, delivering a unified solution for tactile and laser-based measurements. From reverse engineering to first article inspection and in-line quality verification, GAMMA arms provide a powerful toolset to meet the increasing complexity of modern manufacturing.
As industries continue to transition toward smart, data-driven quality control, PMT’s GAMMA series ensures manufacturers are equipped with the tools needed to maintain precision, consistency, and throughput—right at the point of production.
