Material requirements and processing methods for machining mechanical parts

In the mechanical parts processing industry, parts processing is a common job content. Every kind of mechanical equipment needs to cooperate with various components, and the components themselves contain fragmentary parts and configurations. High-quality mechanical parts have an extremely important influence and effect on the machinery industry. The formation of mechanical parts is inseparable from small metal parts. The processing methods of machine parts include die casting, and general mechanical parts are made of metal materials.

There will definitely be many things that need to be paid attention to in the process, and there will be many factors that affect the quality of the product, so be sure to pay attention to some of the details above. What are the material requirements for machining mechanical parts?

The first is the requirement for the hardness of the material. The material cannot be too hard, if it is harder than the mechanical part it cannot be machined.

Secondly, the material should be moderately soft and hard, at least one grade lower than the hardness of the machine parts. At the same time, it also depends on the function of the processing device and the reasonable selection of the machine parts.

In short, there are still certain material requirements for machining mechanical parts, not all materials are suitable for machining, such as too soft or too hard materials, the former is unnecessary, while the latter is unmachinable of.

Therefore, the most basic one is that you must pay attention to the density of the material before processing. If the density is too high, the hardness is also high, and if the hardness exceeds the hardness of the machine parts (lathe turning tools) , it cannot be processed, it will not only damage the parts, but also cause danger, such as the turning tool flying off, hurting people and so on. Therefore, in general, for mechanical processing, the material should be lower than the hardness of the tool, so that the processing can be carried out.

The above points are the requirements for the processing of mechanical parts. Let's take a look at the processing methods, as follows:

Die-casting is a kind of the usual method of operation. Die casting is a metal casting process characterized by the use of a mold cavity to apply high pressure to molten metal. Molds are generally made of high-strength alloys, a process somewhat similar to injection molding. Most die castings do not contain iron, such as zinc, copper, aluminum, magnesium, lead, tin and lead-tin alloys and their alloys. Cold chamber die casting machines or hot chamber die casting machines can be used as required. The cost of castings and molds is high, so the general die casting method can only be used for mass production. The manufacture of die-casting parts is relatively easy, which generally only requires four steps, and the single cost increment is very small. It is especially suitable for producing a large number of small and medium-sized castings, so it is the most widely used one in various casting processes. Compared with other casting processes, die castings have a flatter surface and higher dimensional consistency.

The above are the material requirements and processing methods of mechanical parts processing. Today we will talk about it first. If you want to know more news about this, please pay attention to YIFENG Learn more on the METAL Technology website.
