The Fully CNC Automatic VMM is a vision measurement machine that features auto vision having an auto zoom lens, probe, and four-axis motorized control. It has a 3-axis full automatic measurement and powerful functionality, simple operation, and is designed for wide-ranging applications. The system consists of a three-axis CNC controlling, automatic measuring function, and a high-definition zoom lens. The sharp measuring images can be realized using high-definition special images. An accuracy up to 1um is thus achieved because the system adopts a high-precision P-grade linearity guide, German high-precision toothless screw, and open-type high-resolution linear scale.
