Gantry CMM Machine Range from COORD3

Inspection of large components on a Coordinate Measuring Machine requires a blend of large volume measuring capability and high accuracy performance. With almost 40 years of experience in the design and construction of machines designed for such application we provide a wide range of Gantry style CMM’s characterized by supreme mechanical design and structural stability that ensure long term accuracy performance.

The COORD3 MCT range of Gantry style CMM offers a range of medium to large measuring volumes and has been developed for measuring larger manufactured parts. The MCT Gantry can be supplied with dual scales and dual drives on its longituinal axis for improved metrological performance. This optional feature is particularly beneficial on the largest models where the transverse axis is 3000mm and above.

Uniquely the smaller model sizes of MCT Gantry CMM can also be supplied with an integral Monolithic base negating the requirement for a special foundation and ensuring that the machine can be moved at some future point; an all too frequent request in a dynamic manufacturing company.

The MCT Gantry excels when inspecting large-scale components such as ship engines and transmissions, aeronautical structures, turbines and components for nuclear and thermal power plants and wind turbines. Inspection of large-scale parts are easy to perform with a true Gantry CMM due to its open access structure.

COORD3 have supplied most of the largest Gantry style CMM machines ever built. COORD3 Gantry CMM models can be supplied with up to a 5000mm Y axis, 3000mm Z axis and X axis up to 20,000mm. COORD3 is the Gantry CMM platform supplier to both Zeiss and Nikon Metrology.

When sizing up the competition…its all about TIME

A COORD3 Gantry CMM can be suppled with the Renishaw REVO 5 axis probing technology making the CMM the most productive available. REVO provides the ability to measure component features using ‘Head Touches’; the unique new CMM measuring technique that measures using only the motion of the probe head completely eliminating CMM motion during feature inspection with a dramatically improved CMM productivity and metrology performances.

The REVO can be used in Touch, 3 Axis Scan or full 5 Axis Scan modes.

CMM X Main Carriage

The distance between the Y axis guide-ways combined with wide air bearings spreads on the main carriage are designed to provide a ratio which is best in class ensuring that accuracies are preserved during high speed motion and heavy duty operations such as milling and scribing. The main carriage design combines high strength and maximum rigidity to eliminate X axis roll during machine motion.

The X and Y axes utilize rack and pinion drives providing maximum rigidity of motion and backlash free performance which are optimum requirements to ensure outstanding accuracy both during general inspection and continuous scanning applicatiions.

CMM Y Guide-way Beams

The longtitudinal beams are fabricated from stabilized ribbed steel for maximum stability and supported on a series of pillars. Guide-way beams can be joined together allowing the ‘X’ axis to be 12,000mm or even longer as the application demands. The support pillar mounts are so engineered to allow linear expansion of the beams without introducing structural stress, distortion or CMM accuracy degradation. Air bearings provide contrast providing enhanced rigidity and friction free motion on all axes.

CMM Carriage and Z Ram

The Z axis carriage is manufactured from cast aluminum reinforced with structural ribs providing excellent rigidity in a lightweight frame. The column, which travels inside the carriage and provides CMM Z motion, is supported by wide bearing spread air-bearings maintaining the highest accuracies throughout the range of available measuring strokes. The pneumatic counter-balance located inside the ram balances the weight of the ram and the mounted measuring probe or milling and scribing tools.
