In the design process of aluminum alloy die castings, many customers are uncertain about the thickness of aluminum alloy die castings, and they do not know how thin the thickness of aluminum alloy die castings can be. Read more

According to the introduction of precision CNC machining manufacturers, the large-scale CNC machining parts are made of bar materials, and the process plan of rough machining and finishing is adopted. The specific process flow is as follows: blank → rough turning → rough milling → aging → fine turning → fine milling.

 

CNC lathe is a kind of high-precision and high-efficiency automatic machine tool. The use of CNC lathe can improve processing efficiency and create more value. The emergence of CNC lathe has made enterprises get rid of the backward processing technology. The processing technology of the lathe is similar, and the processing technology of the CNC machine tool has the characteristics that other machine tools cannot match.

 

Rough milling: According to the analysis of precision ODM processing manufacturers, a margin of 1.5mm is reserved on the side and bottom of the cavity, and the process hole is pre-drilled at the hole position of φ12mm. Aging: Removal of material and processing stress. Finish turning: Finish turning the end face, the outer circle and boring the process hole φ6mm. It is required to complete the clamping in one time to ensure the coaxiality and lay a good foundation for the subsequent processing. Precision milling: to ensure the final requirements of the parts, is the focus of this article.

 

①Rough milling cavity rough machining mainly removes large margins and lays a good foundation for subsequent finishing. Therefore, when machining the cavity, choose a low-cost common digital control CNC machining milling machine. This process requires that the inner contour is machined according to the shown part structure drawing, the arc corner is R5mm, and the remaining finishing allowance is uniform, which is 1.5mm. And this process also needs to pre-process the positioning holes required for finishing at the φ12mm hole position.

 

②The high-speed machining technology of precision milling cavity is a manufacturing technology that has been applied in recent years. In high-speed cutting processing, due to the small cutting force, the machining deformation of the parts can be reduced, which is more suitable for thin-walled parts, and the chips are removed in a short time, most of the laser cutting heat is taken away by the chips, and the workpiece is thermally deformed Small, it helps to ensure the accuracy of the size and shape of the parts; high-speed machining can obtain higher surface quality, and the machining cycle is greatly shortened. Therefore, in combination with the characteristics of this type of thin-walled disc parts, high-speed machining is selected when finishing the cavity.

 

③Introduced by the precision CNC aluminum machining manufacturer, the positioning hole is processed by the center hole φ6mm and φ12mm hole as the positioning hole for the finishing of the part, so it must be machined in place before finishing the cavity.

For zinc alloy die castings to be electroplated surface treatment, this link is very important. If the electroplating is not done well, all the work in the early stage will be wasted. Therefore, we must pay attention to the electroplating process of the product. Then the quality of electroplating is affected by those factors. Carbide die casting summarizes the following for you: Read more

Modify tool offset value to ensure dimensional accuracy

 

According to stainless steel parts machining manufacturers, when the workpiece error exceeds the workpiece tolerance due to the first tool setting error or other reasons, and the processing requirements cannot be met, the workpiece can be modified to achieve the required size by modifying the tool compensation. The method to ensure the radial size is as follows: Read more

After the CNC machine tool is produced by the manufacturer, the machine tool has been subjected to various requirements and inspections, and only after passing the inspection, can it leave the factory. Regarding medium and large CNC machine tools, because the machine tools are large in size and not convenient for transportation, they must be distinguished and transported to the user after they collapse before they can be used before they can be reassembled and debugged. As for small machine tools, the float level gauge does not need to crash the machine tool during transportation, so the installation, debugging and acceptance tasks of the machine tool are relatively simple.
