Cold forging process is one of the new processes of metal process without machining. It is a kind of plastic deformation produced by using metal under the action of external force, and a processing method with the aid of mould, the volume of metal is redistributed and transferred, thus forming the necessary parts or blank. Cold heading process is most suitable for the production of bolts, screws, nuts, rivets, pins, bushings, sleeves and other hollow parts and shapes.

The sheet metal stamping is one of machining process, It`s also named pressing. Stamping is a forming method to use presses and dies to exert external forces on plates, strips, pipes and profiles, resulting in plastic deformation or separation, thus obtaining the desired shape and size of the work piece (Metal stamping parts). Stamping and forging belong to plastic processing(or pressure processing), collectively known as forging. The blanks are mainly hot-rolled and cold-rolled steel sheets and strips. Of the world`s steel, 60 to 70% are plates, most of which are stamped into finished products.

As versatile a material as the copper-zinc alloy brass can be processed in just as diverse ways. Of course, it depends on the form in which it is present as a basic material and what should arise from it.

With the development of building doors and Windows, curtain walls, vehicles, ships and automation equipment, aluminum machining service center has gradually developed into an independent processing center. According to the characteristics of aluminum, aluminum cnc service center has the ability of milling groove, drilling, tapping, etc. And the function of milling plane/surface, spot facing, bore a hole and so on is rarely used in aluminum machining service. Due to the characteristics of the processing objects, the design of aluminum machining service center is very different from the general processing service center from structural layout, technical parameters to numerical control system.

CNC Numerical Control milling machine in the CNC engineering services is controlled by digitizing signals with an electronic meter. Numerical control milling machine is a kind of automatic machining equipment developed on the basis of general milling machine. Both of them have the same processing technology and similar structure. Numerical control milling machine is divided into two categories: no - strip and strip. CNC milling machine with cutter library is also known as machining center.
