I Usage                                                                        VMS Series is an economical type CNC video measuring system produced by Yihui. It has been widely used in machinery, electronics, metalwork, plastics, mould, and other industries for precision automatic measurement. 

II Features                                                                   
1. Double closed-loop motion control, motor in high-speed movement with precise positioning performance.
2. Using the embedded modules developed to control motor, increasing motor speed accordingly, but also to simplify the instrument and the PC-interface, PC machines and instruments through the USB line and S-Video cable.
3. Surface light source formed by an independent group of *4, each group are constant current source driver and ***-step continuous variable.
4. With my company-specific CNC software has greatly enhanced the efficiency measurement.
5. Granite base, column, high stability.
