The quality of the machine depends on the processing quality of the parts and the assembly quality of the machine. The machining quality of the parts includes the machining accuracy and surface quality of the parts. The difference between them is called processing error. The machining error reflects the accuracy of machining. The greater the error, the lower the machining accuracy, the higher the machining accuracy. The main aspects that affect machining precision: dimension accuracy, the actual size of the part after processing and the degree of conformity of the tolerance belt center of the part size.

Compared with the method of producing parts with die casting, it avoids the uneconomical use of die in the manufacture of small batches of parts, and the production cycle is greatly shortened. At the same time, the correct positioning of the clip and the reasonable processing technology make the processed parts have higher accuracy and surface finish, which is not achieved by the die casting process. Moreover, the density of extruded aluminum profiles is relatively high, and the strength of the processed parts is higher than that of pressed castings.

In addition, this method is different from the general single part machine processing production, it can produce a piece of parts in bulk. If the workbench of the machine tool is large enough, the bottom plate can be made larger, and several aluminum materials can be arranged at a time. The processing efficiency can be further improved, and the number of replacement knives can be reduced. If the side of the part has features to be processed, for example, there are round holes to be drilled, the part must be made into a fixture and the part must be reprocessed after the B-side is cut off.
