Gantry-type CMMs feature a distinctive structure combining a fixed base and a sliding gate. The main shaft structure moves over a fixed table to conduct measurements. This design makes it ideal for measuring large parts such as those found in automobiles and aircraft, heavy items, and satellite communication equipment.
Here, we introduce various gantry-type CMMs offered by different manufacturers. If you're considering implementing a gantry-type CMM, this page will be an excellent resource to explore your options.
The FALCIO-Apex 2000/3000 Series by Mitutoyo is a specialized CMM for high-accuracy measurement of large and heavy objects. Featuring a unique foundation-mounted structure with a moving gate and high-accuracy linear encoders, it offers exceptional position detection capabilities and machine control. Particularly as a large gantry-type CNC CMM, it is capable of inspecting precision large-scale parts.
A key feature of this series is its ability to measure super-heavy objects that cannot be mounted on a measuring table. Mitutoyo’s original separate guide structure enables simultaneous three-dimensional and high-accuracy measurement of large, heavy products. The length measurement unit incorporates Mitutoyo’s high-accuracy linear encoders, enabling accurate machine control.
The optional MOVAC system provides an automatic restoration function for accuracy deterioration due to foundation deformation. The series also includes a temperature compensation feature, ensuring accuracy across a wide range of temperature environments. The guide method employs air bearings in each axis, and various safety devices (Z-axis beam sensors, tape switches, area sensors, etc.) are also available as options.
The FALCIO-Apex 2000/3000 Series is well-suited for system construction in production sites and other locations for process management. It monitors measurement results in real-time, detecting abnormalities in work processes to prevent defects.
Specifications can be chosen according to the machine's intended purpose, with X-axis measurement ranges from 2000 to 3000mm, Y-axis from 3000 to 5000mm, and Z-axis up to 1500mm, catering to diverse needs. With its high-level performance and ease of use, the FALCIO-Apex 2000/3000 Series is an excellent choice for high-accuracy measurement of large and heavy objects.
ALPHA, developed by Hexagon Metrology, is a versatile and flexible gantry-type CMM designed for dimensional inspection of large cast iron and machined parts. It is equipped with options for high-productivity 3D scanning laser heads and continuous servo wrists, making it suitable for production processes involving molds. An optional bellows cover is also available to protect the machine from dirt.
Based on innovative technology and solutions, ALPHA has a strong track record of installations around the world, attesting to its reliability. It is capable of measuring not only large automotive and aerospace parts but also heavy objects and satellite communication equipment. Its features include slant bridge technology, lightweight aluminum alloy construction, high speed and acceleration, continuous axis movement compensation, and options for non-contact sensors.
There are two versions of ALPHA available: ALPHA Classic and ALPHA Performance, each suitable for different applications. ALPHA Classic is ideal for dimensional inspection of large castings and machined parts. Its optical scanning sensor makes it recommended for reverse engineering and mold production processes.
On the other hand, ALPHA Performance isa high-performance gantry-type CMM equipped with advanced devices and high-rigidity silicon carbide spindles. I performs exceptionally well in any operational condition thanks to its linear temperature currection function.
