Numerical control machining is a process method of machining parts on CNC machine tool, which uses digital information to control the displacement of parts and cutting tools. It is an effective way to solve the problems of small batch, complex shape and high precision. What should we pay attention to in NC machining?
1. The burr on the surface of the workpiece is easy to be ignored by many manufacturers. In fact, for a part, CNC machining parts are processed by equipment, so the burr will be produced during injection molding, and the burr is also produced at this time. If it is not trimmed in time, the part is likely to be invalid, It will also affect other links when it is used.
2. The accuracy of parts is very strict for the accuracy of parts processed by numerical control lathe. Only when the required accuracy is reached can the accuracy be used. The judgment of this accuracy mainly depends on the control ability of dimensions. If the accuracy is within the range of tolerance fluctuation, the parts are qualified, and if it exceeds the tolerance, it is unqualified.
3. Analyze the test results. Before the parts leave the factory, they must have a performance test. If the performance is qualified, they should leave the factory immediately. If the performance is not qualified, some reasons should be analyzed. In this way, a large number of scrap can be avoided. The manufacturers in the processing industry basically deal with it in this way. They will deal with it according to the performance of many manufacturers, Make a certain quality control chart, so as to analyze the reasons.
