With the rapid development of the processing industry, we will encounter various reasons during processing. The products will be affected by processing and the quality will decline. So what is the reason for the failure of precision parts processing?
The reasons for the failure of precision parts processing can be summarized into four aspects: material, installation and use, processing and design.
1. Material reasons Improper material selection is the main reason for material failure. Most often, designers make decisions based solely on the material's conventional performance indicators, and the defects of the material itself are also the cause.
2. When installing and using the parts that have already failed, if the fit is too loose, too tight, can not be fixed, poor alignment and improper operation may cause the use of failure.
3. In terms of processing, various defects will be formed due to poor processing technology control, which will cause failure. If the heat treatment process is not properly controlled, it will lead to overheating, lack of tempering, decarburization, etc. Overheating or overburning, etc. Poor cold working process will result in too low brightness, too deep knife marks, grinding cracks, etc., which can lead to the failure of parts.
4. Design reasons:One is that the parts fail due to the unreasonable structure and shape of the design. For example, there are obvious stress concentration sources in the high stress area of the parts. The second is the wrong estimation of the working conditions of the parts, such as the lack of estimation of the possible overload in the work, so that the bearing capacity of the designed parts is insufficient.
