Causes of the failure of precision parts processing

At present, precision parts processing is doing more and more outstanding in the processing industry. It is because of its excellence that it has brought us a lot of convenience, and the scope of its use is getting wider and wider.

Precision parts processing refers to the entire process of making original materials (or semi-waste) into products. For precision parts processing, it includes the transportation and storage of original materials, consumption preparation, blank manufacturing, parts processing, heat treatment, product assembly, and debugging, paint and packaging, etc. The content of precision parts processing is very common. Modern enterprises use the principles and methods of system engineering to organize and guide consumption, and regard precision parts processing as a consumption system with input and output.

When processing precision parts, the process of modifying the shape, size, position, properties of the object to be processed to turn it into waste or semi-waste is called a process process. This is a major part of the processing process. It is divided into casting, forging, stamping, welding, machining, assembly and other processes. The mechanical manufacturing process generally refers to the sum of the mechanical processing process and the machine assembly process. Other processes are called auxiliary processes, such as transportation, storage, and power. Supply, equipment maintenance, etc. The process is composed of one or several processes arranged in sequence, one of which consists of multiple steps.

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

Silk printing machine manufacturer Dongguan Zhanxun Machinery Technology analyzed the reasons for the failure of precision parts processing from four aspects: material, installation and use, processing and design.

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

2: When installing and using failed components, too loose fit, too tight, unstable fixation, poor centering and improper operation will lead to failure of use.

3: In terms of processing, various defects will be caused by poor control of processing technology. For example, improper control of the treatment process can cause overheating, insufficient tempering, decarbonization, etc. Temperature is too high or overheating. Poor cooling process can cause too low brightness, too deep cuts, grinding cracks, etc. to cause parts failure.

4: The design reason is that the design structure and appearance are unreasonable, resulting in the failure of the parts, such as obvious stress concentration in the high stress area of ​​the parts. Second, errors in estimating the working status of components, such as insufficient estimation of possible overloads during work, making the designed components unable to bear sufficient load.
