GREAT-D series measuring machine is designed for ultra-large workpiece measurement,and its open-type gantry structure has high dynamics and stability,floor-type design meet the need for larger measuring range parts,which may obtain more flexible moving space and facilitate loading,unloading and measurement for large-size and heavy workpiece.
Main feature
The open-type landing gantry structure is available，so as to facilitate the loading and unloading and measurement of the large-size and heavy workpiece.The dual optical scales system can be arranged，thereby，further improving the precision and stability of the machine.
All guide rails use the high-precision&rigidity air bearing，and the rigidity and stability of the machine are improved by means of the encircling guide rail type layout design，so that the high precision can also be maintained even if working for a long time，and meanwhile，the excellent dynamic characteristics of the machine are ensured.
■ Three-axis guide rail are made of high-quality granite，which could keep the same temperature characteristics，and then，have good temperature stability and anti-aging deformation ability，good rigidity and minimum geometry deformation.
■ The application of non-linear spring reduces the influence of minor error of the slide way towards the measuring precision，meanwhile it also guarantees machine’s higher adaptability to the environmental temperature.
■ Z-axis’s torsion plays a critical role in the precision of a CMM.Its reliable anti-torsion structure design also can achieve a high precision in the case of using probe extension bar.Z-axis adopts the adjustable pneumatic balance device，which can adjust the counterbalance with facility although equipped with different probe systems，so that it can reach the best state..
■ The imported high-precision air filter on the machine can assure the ultra high cleanliness of the compressed air，so that could effectively protecting the air bearing and guide rail，meanwhile，the automatic drainage device makes operators economical with time and effort，avoiding the possible harm to the machine caused by man-made negligence.
The bridge cmm machine stands as the gold standard for dimensional accuracy in modern manufacturing environments. Engineered with a rigid, thermally stable bridge structure, this bridge cmm machine minimizes geometric errors even under high-speed probing routines. Its moving bridge design allows for exceptional accessibility to large workpieces, while the air-bearing technology on all axes ensures friction-free movement. Whether inspecting automotive engine blocks or aerospace turbine housings, this bridge cmm machine delivers repeatable measurements down to micrometer levels. By integrating advanced Renishaw probes and intuitive metrology software, the bridge cmm machine transforms raw data into actionable quality reports.
For shops requiring flexible inspection cycles, this bridge cmm machine supports both touch-trigger and analog scanning modes. The granite base and bridge column absorb environmental vibrations, guaranteeing stable performance over decades of use. Automatic temperature compensation further enhances reliability, making this bridge cmm machine suitable for non-climate-controlled floors. With rapid positioning rates up to 500 mm/s, throughput increases without sacrificing precision. Additionally, the modular design simplifies future upgrades—adding rotary tables or tool changers extends the bridge cmm machine’s capability for complex 5-axis measurements.
Calibration routines are streamlined via built-in diagnostic routines and remote service access. The machine’s open architecture also integrates with MES and ERP systems for full traceability. For companies seeking ISO 17025 accreditation, this bridge cmm machine provides certified volumetric accuracy down to 1.5 + L/300 µm. From first-article inspection to batch production control, the bridge cmm machine reduces scrap rates and ensures every part conforms to GD&T standards. Ultimately, investing in a bridge cmm machine means investing in zero-defect manufacturing and long-term competitive advantage.
