High-Accuracy Bridge CMMs

Overview

As brand new generation of three-coordinate measuring machine, EXPERT series are integrated with high precision and environmental adaptability to be applicable for wide measuring scope from medium and small measuring range to great measuring range.
The classical mobile bridge structure possesses the broad feeding and discharging space. The self-adaption metallic frictional transmission system with patent technology effectively improves the dynamic performance of measuring machine, especially be suitable for application of scanning and measuring system.

• The tri-axle is adopted with rectangular guide rail with elaborated design, and the so-called various “Unique “and “Patented” and even strange polygon guide rail structures are abandoned, returning to nature. The correction model upon rectangular guide rail error is simple and practical; the form is most common form in the high-precision measuring machine.
• Long axis is adopted with the most ideal three-coordinate transmission system recognized by industry currently-metallic frictional transmission. Compared with such gear-shape transmission as common synchronous belt and gear rack, the tooth profile efficiency is eliminated completely to enable that the trans­ mission is more steady, effectively eliminate the machine shock brought by the flexible telescoping of synchronous belt and improve the transmission rigidity of measuring machine so as to reach better starting, stopping and positioning capability, which is ideal selection for high-precision scanning measurement.
• The surrounding-type air bearing layout design is adopted uniformly for tri-axle, and the pre-compression air bearing with high air membrane rigidity is utilized. Through comparison between with other layout and surrounding layout on all sides, the pre-compression force for each air bearing may realize the individual control and non-interference mutually to enable that each air bearing can work under most ideal status.
• Two columns of measuring machine are adopted with double layer design fully to lower the influence on measuring machine precision by external temperature change and air conditioner’s air supply system to enable that the measuring machine is provided with more powerful environment adaptability.
• The brand-new pedestal design of measuring machine is completely compatible with high-efficient passive vibration isolation system or positive air vibration isolation system to meet the utilization demand of plant with strong earthquake source and on-line measurement.
