What is the quality of the automated part processing machine?

The quality of the machine depends on the machining quality of the parts and the assembly quality of the machine. The machining quality of the parts includes the machining accuracy and the surface quality of the parts. The machining accuracy of the parts refers to the degree that the actual geometric parameters (size, shape and position) after machining are consistent with the ideal geometric parameters. The difference between them is called machining error. The machining error reflects the machining accuracy. The larger the error is, the lower the machining accuracy is, the smaller the error is, the higher the machining accuracy is; the main aspects affecting the machining accuracy are: dimensional accuracy, the degree of conformity between the actual dimension of the machined part and the tolerance zone center of the part dimension.

Compared with the method of producing parts by die-casting die, it avoids the uneconomical of opening die when manufacturing small batch parts and greatly shortens the production cycle. At the same time, the correct clamping positioning and reasonable processing technology make the machined parts have high precision and surface finish, which is not achieved by the die casting technology. Moreover, the density of extruded aluminum profile is relatively high, and the strength of processed parts is higher than that of die casting. In addition, this method is different from the general single part machining production, it can produce a bed of parts in batch. If the worktable of the machine tool is large enough, the base plate can be larger, and several aluminum materials can be arranged at a time, the processing efficiency can be further improved, and the number of tool changes can be relatively reduced. If there are features on the side of the part to be machined, for example, if there are round holes to be drilled, then after the part is cut on the B side, the fixture shall be manufactured, and the part shall be installed before machining.
