What are the reasons for failure in precision parts processing?

When processing precision parts, you will encounter various reasons, the product will be affected, and the quality will decline. So what are the reasons for the failure of precision parts processing?

1: Improper material selection is the main cause of material failure. In most cases, designers only make decisions based on the conventional performance indicators of the material, and defects in the material itself are also one of the reasons.

2: When installing and using components that have failed, too loose or too tight fit, weak fixation, poor alignment and improper operation will lead to failure.

3: In terms of processing, poor control of the processing technology will cause various defects and cause failure. For example, improper control of the treatment process can cause overheating, insufficient tempering, decarburization, etc. The temperature is too high or overheating. Poor cooling process will cause low brightness, deep knife marks, grinding cracks, etc., which may cause parts failure.

4: The first design reason is that the failure of the parts is caused by the unreasonable design structure and appearance. For example, there is obvious stress concentration in the high-stress area of the parts. The second is an error in estimating the working status of components, such as underestimating possible overloads during work, which makes the designed components unable to withstand sufficient load.
