Often the CNC spring machine can be divided into: computerized compression spring machine, universal spring machine and camless spring machine, etc. 1, from the product structure to distinguish: computerized compression spring machine is mainly used to process a variety of precision compression spring products, such as helical springs, tower springs, conical springs and die springs, etc.; universal spring machine is mainly used to process a variety of compression springs, torsion springs, tension springs, leaf springs, profiled springs and wire forming products. 2, from the machine forming structure to distinguish: computerized compression spring machine is mainly winding a variety of precision compression spring products, the universal spring machine is mainly pressing a variety of spring products, forming principle of the different spring machine functions, oriented to the different product structure. 3, from the line forming elements to distinguish: computerized compression spring machine through the principle of winding, can be dealt with in a circle, arc and straight line elements of product structure; universal spring machine using the compression spring machine to process a variety of compression springs, torsion springs, tension springs, leaf springs, profiled springs, etc.. Structure; universal spring machine using the principle of pressing, can deal with round, arc, straight line and folded corners and other elements of the product structure. Therefore, users and friends in the choice of spring machine, should take into account their product type, precision requirements and demand and other parameters (the above views originated from the Dongguan City, Kaichuang Precision Machinery Co.)
