Before processing large mechanical parts, you must pay attention to the density of the material. If the density is too large, the hardness is also great. If the hardness exceeds the hardness of the lathe tool, it will not be processed. Not only will the parts be damaged, but also the formation Risks, such as a turning tool flying out and hurting people. So, what are the material requirements for the processing of large mechanical parts?
Information about large-scale machining is divided into two categories, metallic materials and non-metallic materials. Regarding metal materials, the hardness of stainless steel is the largest, followed by cast iron, followed by copper, and finally aluminum. The processing of ceramics, plastics, etc. is attributed to the processing of non-metallic materials.
Stainless steel materials used in the processing of large mechanical parts
1. First of all, the hardness of the material is required. For some occasions, the higher the hardness, the better, but it is limited to the hardness requirements of the machined part. The processed material should not be too hard. If it is harder than the machine part, it cannot be processed.
2. Secondly, the material is moderately hard and soft, at least one grade lower than the hardness of the machine part. At the same time, it depends on the purpose of the processing equipment and the reasonable selection of the machine parts.
In short, large-scale machining still has some requirements for materials. Not all materials are suitable for processing. For example, materials that are too soft or too hard, the former is not necessary for processing, and the latter cannot be processed.
Therefore, in general, for mechanical processing, the material material is lower than the hardness of the machine knife, so that it can be processed. Not all materials can be precisely processed. Some materials are too hard to exceed the hardness of the processed parts, and the parts may collapse. Therefore, these materials are not suitable for the processing of large mechanical parts, unless they are made of special materials. Into the machine parts, or laser cutting.
