DH Series: convenient, stable, multi-DH series is triggered measurement integrated measurement and optical measurement techniques combined solution. Primarily for automotive, appliance, electronics, cell phones, touch screen, the plastics industry and precision machinery industries. ? Measuring machine used in all 00 marble and double cross table structure, compact structure, its advanced mechanical design ensures overall system accuracy and high stability;? Advanced high-precision CCD imaging technology and advanced image processing technology the perfect combination to achieve specific measurement requires a computer programmed to control the optical illumination (top light, bottom light ring light) technology, so that the surface illumination uniformity and improve the accuracy and reliability of measurement;? triaxial mechanically mutual independence movement interfering, thus ensuring the high stability of the system;? three axes are made with high-precision V-Taiwan HIWIN rail, with the same material as the body, which has a good temperature stability, the effectiveness of anti-deformation capacity, steel good, dynamic geometric distortion smallest error;? XY axis all use patented technology toothless gear nut, which greatly improves the stability of the XY axes and automatically adjusts the pressure of high long-life reliability patented technology. ;? Z-axis DSP digital controller with a stepper motor which greatly improves the operability of the machine, to avoid trouble manually adjust personnel standing z axis is also greatly improved work efficiency.
