Reasons for CNC machining failure

There are many reasons for the failure of CNC machining. There are not only one but also many kinds. It may be due to the operation error in the processing process or the poor selection of materials. These are one of the reasons for the failure, and the same is true for CNC processing. What are the reasons for the failure of CNC processing?

1. The main reason of material failure is improper material selection. The most common is that the designers of CNC machining only make decisions according to the conventional performance indicators of materials, and the defects of materials themselves are also the reasons.
2. When installing and using the failed parts, if they are too loose, too tight, fixed, poor alignment and improper operation, they may lead to the use failure.
3. In CNC machining, due to the poor control of processing technology, various defects will be formed and lead to failure. For example, improper control of heat treatment process leads to overheating, lack of tempering, decarburization, etc. Overheating or over burning. Too deep, too low degree of grinding will lead to poor machining process.
4. The first reason for the design is that the structure and shape of the design are unreasonable, which leads to the failure of the parts. For example, there are obvious stress concentration sources in the high stress area of the parts. The other is the wrong estimation of the working conditions of the parts, such as the lack of estimation of possible overload in the work, so that the bearing capacity of the designed parts can not be reduced
