UG series Composed CMM has the adoption of the design of air-bearing gantry support, which is composed of fixed frame and mobile worktable .AEH is the only one company that can manufacture this model, whose advanced mechanical structure guarantees the integrated high precision and stability of the system. Our company fuses many modes of probes, such as Contacted probe, optical probe and laser probe, into the whole one, so that it can guarantee completing almost .the whole measuring tasks. It plays an important part under the complex condition of high-precision testing of mechanical parts. In 2002, National ministry of education invited public bidding this series, and in China , many academes purchase and use it. It plays a very important role in the research and teaching affair.
