Stainless steel cnc machining services  materials Stainless steels are often referred to as problem materials in the field of machining. Above all, the great toughness of stainless steels and their tendency to stick is causing difficulties for many users. Stainless steels, for example, are increasingly prone to build-up edge with increasing nickel content. Also important for the assessment of machinability is the chromium content. Stainless steels are divided into three main groups: austentia, ferritic / martensitic and duplex steels. The steels of the first two groups are significantly better to cut than the latter (see Figure 1). The largest share is held by the austenites; here can again be divided into 4 groups: In optimized for machining so-called "prodec" steels, as they are z. B. Sandvik steel under the trade name "Sanmac" and in normally machined materials, such as 1.4401 or 1.4436. In addition, there are two particularly demanding material clas...

Forging is a processing method that uses forging machinery to pressure the metal blanks, which obtains certain mechanical properties, certain shape and size of forgings by the plastic deformation of the metal blanks. It is also one of the two major components of forging (forging and stamping). Forging can eliminate defects like loose as cast condition that produced in the smelting process of metal and optimize the microstructure. At the same time, the mechanical properties of forgings are generally better than the same material castings because of the preservation of a complete metal flow line. Most of the important parts with high load and severe working conditions in the related machinery use forgings except some simple shape parts can use rolling plate, profiles or welding parts. Deformation temperature The starting recrystallization temperature of steel is about 727 ℃. However, 800℃ is widely used as the dividing line: the hot forging is higher than 800 ℃; the forgin...

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. Ningbo Hewcho manufacture a wide variety of cold forging parts. These parts are applied to automotive, electronics, mining, hydraulic and pneumatic, machinery, and general industry. Using the latest in forging technology, we currently have the capacity to produce more than thirty million cold forged parts per year. To provide additional value to our customers, we also have the capability to provide finished, machined parts, or semi-machined parts, after the forging process. The advantages cold forging proce...

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. The aluminum beam and frame aluminum of general equipment all need deep processing before being used. They need to saw, punch, tap, mill, and so on. There are general processing services and CNC process services in domestic aluminum machining service. Select the machine according the...
