Trade Term: EXW,FOB,CIF.CFR Payment Term: T/T,L/C, Western Union Delivery Time:7-30days Place of Origin: Ningbo, China Stainless Steel Parts Features: Chemical Composition Corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, most stainless steels have low carbon content, the maximum is not more than 1.2%, and some steels have ωc (carbon content) even lower than 0.03% (eg 00Cr12 ). The main alloying element in stainless steel is Cr (chromium). The corrosion resistance of steel is only when the Cr content reaches a certain value. Therefore, stainless steel generally has a Cr (chromium) content of at least 10.5%. Stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, Si, and Cu. Stainless steel machining components have the following features: Weldability: Stainless steel machined products have good weldability. These products can be used for vessel parts, water heaters, drinking fountains, etc. H...

Aluminum milling service  is one of the numerical control services, which is widely used in the machinery manufacturing, mold processing and so on. Based on the ordinary milling service and combined with the characteristics of the numerical control machine tool, aluminum CNC milling service can complete not only the ordinary milling service, but also those are difficult for the ordinary milling service. Aluminum CNC milling service equipment mainly consists of CNC milling machine and machining center, which can be used for planar contour milling and curved surface contour machining, as well as drilling, expansion, grinding, boring, panting and thread machining. There must be CNC milling machine in the Aluminum CNC milling service. CNC machining center is a machine tool that adopts CNC technology. To be specific, the aluminum CNC milling service information such as cutter's moving track is recorded on the program medium with digital code, and then the data is transferred to the n...

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. Functional features of CNC engineering services In addition to the characteristics of ordinary milling machine, CNC milling also has the following characteristics: CNC engineering services are with good adaptability and flexibility of parts processing. It is able to process parts with complex contour shape or difficult to control size, such as mold parts and shell parts; CNC engineering services can process parts that cannot be processed or difficult to be processed by ordinary ma...

Stainless steel machining china   service 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 classes ...
