Gantry CMMs

Overview

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.
