In order to meet the requirements of precision measurement and quality verification of aerospace, automobile inspection tools, fixtures, molds and parts, Beijing Jingke is equipped with advanced Heikeskang automatic gantry CMM, automatic bridge mobile CMM and Zhongce CMM, as well as professional and skilled CMM. Beijing Jingke has an independent measurement workshop, as well as the constant temperature and humidity in the measurement room, which ensures the measurement effect of the inspection fixture products. Three-coordinate measurement is a measurement method that measures the three-dimensional coordinates of the zero surface point by using the digital technology that converts the physical object to the CAD model through the mutual movement of the measuring head system and the parts. Three-coordinate measurement has the characteristics of high precision, fast speed, good flexibility, and strong data processing capabilities. It is widely used in the automotive, machinery, aviation, electronics, and hardware industries. It is mainly used for precision detection of the shape, size, tolerance and assembly process of parts.
