There are definitely many things that you will pay attention to during processing, and there are also many factors that affect the quality of production, so we must pay attention to some details of the above problems, then let’s understand what the fine processing requests for materials ? The first is the request for the hardness of the material. For some places, the higher the hardness, the better, but it is limited to the hardness request of the machined part. The processed material should not be too hard. If it is harder than the machine part, it cannot be processed.
Secondly, the material is moderately soft and hard, at least one level lower than the hardness of the machine part. At the same time, it also depends on the purpose of the processed device and the reasonable selection of the machine part. In short, there are still some requirements for materials for fine machining. 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 other cannot be processed.
Therefore, the most fundamental one is that you must pay attention to the density of the material before processing. If the density is too large, the hardness is also large. If the hardness exceeds the hardness of the machine (lathe tool), it cannot be processed, not only It only damages the parts, but also poses a risk, such as a turning tool flying in and hurting people. Therefore, generally speaking, for mechanical processing, the material material is lower than the hardness of the machine knife, so that it can be processed.
