There are many kinds of Metal parts processing types of mechanical drawing processing, of which CNC parts processing is a very common one, according to its processing process is mainly divided into the following methods. Let me talk to you a little bit. 
The first, the tool concentrated sorting method. The principle of this method is very simple, it is based on the tool used to divide the process, in simple terms, first use a knife to complete all the processing processes on the metal parts, and then use a second knife, and then the third knife until the completion of all the processing processes. This processing method is to reduce the inconvenience caused by frequent tool changes, can also speed up the overall progress of mechanical drawing processing, and can also reduce unnecessary positioning errors. The second, rough and finish processing method. In simple terms, it is to do rough machining or semi-finishing of a single part first, and then carry out finishing operation. Then, for a large number of parts, the first unified rough processing, and then semi-finishing, and finally complete the mechanical finishing work. Special attention should be paid to the gap between rough and finish machining, and it must be buffered at intervals of time, so that the deformation of the parts after rough machining can be fully recovered, and then finished after recovery, which can improve the processing accuracy of the parts, thereby increasing the qualified rate of the finished products. The third, according to the processing parts of the sorting method. This method is that when CNC parts are processed, the plane is processed first, and then the drilling is processed. It can also be explained in this way that simple geometric shapes are processed first, and complex geometric shapes are processed later. That is, the place where the processing accuracy is low first, and then the place where the processing accuracy is relatively high. In short, we process parts on CNC machine tools, and the processing process of parts must be analyzed according to the situation of the parts themselves, to see which processing method is more suitable, and then carry out mechanical drawing processing work.
Finally, summarize the CNC parts processing process. We all know that CNC parts processing is carried out according to the needs of production, and after the opening of the material, like small parts production, you can first go to the punching machine processing, and then the gong cutting or CNC processing. This method is used more in the glass parts processing and auto parts production industry. However, if it is to process the container, it is necessary to first carry out the opening punch and then burn the bright, and then sand, spray oil, and finally assemble the accessories so that the finished product comes out.
