The computer controller of analytical spring machine such as Yong Teng Spring Machine produced by Huayida is the core command post to operate the whole CNC spring machine. Through the entrance of computer controller, every specific action of spring forming is controlled and coordinated. When the computer controller of the spring machine is abnormal in operation, please first check whether the I/O board works normally. Then check whether the connection line of the switch board is correct, and then further check whether there is noise interference.

Spring is a kind of mechanical part that works by elasticity, which is widely used in machines and instruments. The upstream of the industrial chain of spring manufacturing mainly involves steel and wire industry; Downstream applications involve industries such as automobiles, construction machinery, electric power and household appliances. In terms of upstream supply, as one of the main raw materials for spring manufacturing, the supply of spring steel is relatively stable in recent years, but high-grade spring steel mostly depends on imports; In terms of downstream demand, with the development of automobile industry and railway construction, it provides a continuous growth momentum for spring demand. In the future, with the growth of national investment in the "urban rail transit" industry in the seven major industrial fields of "new infrastructure" and the improvement of urbanization rate, the urban rail transit field will once again stimulate the demand vitality of spring products.
