(1) According to the introduction of imported CNC lathe processing manufacturers, the tool centralized ordering method is to divide the processes according to the tools used, and use the same tool to machine all the parts that can be completed on the part. Use the second knife and the third knife to complete other parts they can complete. This can reduce the number of tool changes, reduce idle time, and reduce unnecessary positioning errors.

(2) Sorting method by processing parts For parts with a lot of processing content, the CNC lathe processing part can be divided into several parts according to its structural characteristics, such as inner shape, shape, curved surface or plane. Generally, the plane and positioning surface are processed first, and then the hole is processed; the simple geometric shape is processed first, and then the complex geometric shape is processed; the parts with lower precision are processed first, and then the parts with higher precision requirements are processed.

(3) Imported CNC lathes are processed by roughing and finishing in order. For parts that are prone to deformation, due to the deformation that may occur after the roughing of CNC lathes, they need to be corrected. Generally speaking, rough and finishing are required. All processes must be separated.

To sum up, when importing CNC lathe processing, when dividing the process, it must be flexibly controlled according to the structure and manufacturability of the parts, the functions of the CNC lathe, the number of parts processed by the CNC lathe, the number of installations and the production organization of the unit. It is also recommended to adopt the principle of process concentration or the principle of process dispersion, which should be determined according to the actual situation, but must strive to be reasonable.
