Composite machining is one of the most popular machining processes in the world of machining. It is an advanced manufacturing technology. Compound machining is to realize several different machining processes on one machine tool. Compound machining is the most widely used and the most difficult, that is, turning and milling compound machining. The turning and milling compound machining center is equivalent to the compound of a CNC lathe and a machining center.

　　The equipment can effectively ensure high accuracy and good stability, and also effectively ensure the accuracy of the actual test data; the connecting rod and the load rod of the sample holder are made of the same material, the same diameter, and use Made of low-expansion alloys, the equipment can minimize the deformation of the sample holder and effectively improve the accuracy of the experimental results.

Hardware is a common product produced in daily life. From small parts to large equipment, most of them use metal stamping technology. There are elites in all walks of life, and so are products. The requirements for stamping products must be calculated in mm.

The technology accumulation of the coil spring machine has gradually become mature. Each equipment manufacturer has set up its own professional R & D department, and even cooperated with some professional universities and research institutes in the field of wire forming to develop the latest equipment. For example, the combination of the latest technology and the latest control technology of the German equipment has reached an unreachable height
