Product Details of Oem Cnc Metal Parts
The processing performance of oem cnc metal parts refers to the adaptability of metal materials to different processing techniques. Including casting performance, forging performance, welding performance and cutting performance, etc.
(1) Casting performance
The ability of metals and alloys to be cast into excellent castings after smelting is called casting performance. Casting performance mainly depends on the fluidity, shrinkage, composition uniformity and segregation tendency of liquid metal.
① Mobility. The ability of liquid metal to fill the mold cavity is called fluidity. The metal with good fluidity can easily fill the entire mold, and the casting has precise dimensions and clear contours. If the fluidity is not good, the metal cannot fill the cavity well, and the casting of the desired shape cannot be obtained, and the casting will be scrapped due to "lack of meat".
The fluidity is mainly related to the chemical composition, casting temperature and melting point of the metal material. For example, cast iron has better fluidity than steel, and it is easy to cast castings with complex shapes. For the same metal, the higher the casting temperature, the better its fluidity.
② shrink. When the metal material is solidified from liquid to solid, its volume shrinkage is called shrinkage. That is, the volume and size of the casting decrease during solidification and cooling. The shrinkage of castings not only affects the size, but also causes defects such as shrinkage cavities, porosity, and internal stress in the castings; especially during the cooling process, it is easy to deform or even crack. Therefore, the metal material used for casting should be selected with a small shrinkage rate as much as possible. The size of the shrinkage mainly depends on the type and composition of the material.
③ The influence of uneven composition on the quality of the workpiece. When casting, it is difficult to obtain castings with a very uniform chemical composition. After solidification of castings (especially thick-walled castings), inhomogeneous chemical composition will appear in different parts of the cross-section and different areas inside the grains, which is called segregation.
Segregation can make the structure and properties of various parts of the casting inconsistent. The chemical composition of the casting is not uniform, which will reduce its strength, plasticity and wear resistance. The main reason for segregation is that the alloy has a wide range of solidification temperature, high pouring temperature, fast pouring speed and cooling speed.
Severe segregation will cause great differences in the mechanical properties of various parts of the casting and reduce the quality of the casting.
(2) Stamping performance
The degree of difficulty with which metal materials can be formed under pressure processing (forging, rolling, etc.) is called pressure processing performance. It is related to the plasticity of metallic materials. The better the plasticity of the metal material, the smaller the deformation resistance, and the better the pressure processing performance of the metal material.
①Forgeability. The forgeability of metal materials refers to the ability of metal materials to change shape without cracks during press processing. Steel can withstand hammer forging, rolling, drawing, extrusion and other processing techniques, showing good forgeability.
②Forgeability. The ability of a metal to withstand working under pressure is called malleability.

oem cnc metal parts processing technology
Machining, stamping, precision casting, powder metallurgy, metal injection molding, laser processing, EDM, ultrasonic processing, electrolytic processing, particle beam processing and ultra-high speed processing, etc. Similar to turning, milling, forging, casting, and grinding, CNC machining and CNC numerical control centers are all conventional machining.
If a piece of metal wants to be processed into the shape and size we want, it needs to go through a series of processing procedures. For example, the current broaching machine equipment is specially responsible for broaching, which is one of the important means of fine processing metal workpieces. Now many manufacturers are oem cnc metal parts, so what are the advantages of broaching?
1. In terms of production efficiency, broaching is undoubtedly particularly advantageous. The shape of the broach may not be seen by many people. It is actually a tool with a multi-tooth structure. When the broach receives the workpiece, the broach will complete fine machining, rough machining and semi-finish machining in one stroke. These three processing steps are very fast.
2. In terms of the scope of application of processing, broaching can not only process metal planes, but also complete through-hole operations, so the application area is still relatively wide. Basically, most metal plates will go through such a process as broaching.
3. In terms of processing precision, broaching is not far behind. The broach of each broaching machine is specially calibrated. The function of the calibrated part is to make the local calibrated size more precise, and then adjust the light correction amount, so as to improve the surface material of the metal workpiece.
4. The broaching process is actually very simple, because its structure is very simple. In fact, it is a process of moving the metal in a straight line and then pulling it with a broach. No special professional is required to operate it.
5. The broaching tool used in the broaching process has a very long service life. Many people may ask how can the service life be guaranteed after such a long period of working wear? In fact, the broaching speed of the broaching tool is relatively slow. , so the degree of wear is not high, and a broach can basically process thousands of workpieces.
