Generally speaking, when the three-axis machining center completes the processing of the deep cavity mold, it can only be realized by adding the tool and the tool holder. In the five-axis machining mold, the clamping is performed once, through the movement of the swing table or the swing axis. , Use a flat-bottomed end milling cutter to process each surface of the mold by keeping the tool axis perpendicular to the processing end surface, which can reduce processing costs and reduce processing time.
At the same time, the five-axis machining center is also suitable for milling angled sides. The machining process can avoid the rib-like pattern caused by the beveled surface of the ball end mill on the three-axis machining machine, so that the surface quality of the mold can easily meet the expected requirements, and also avoid A series of problems such as the positioning error and the non-coincidence of the reference plane during the second positioning of the conventional machine tool during the second positioning are solved.
This not only shortens the time for auxiliary debugging and processing of the workpiece, but also reduces the errors that occur, and the cost of fixtures, tools, etc. required in the installation of the workpiece is also reduced. When machining parts with complex parts such as thin walls, corners, and curved groove bottoms, three-axis machining uses ball cutters for fine milling. The purpose is to improve the surface quality, but because the center of the ball cutter rotates The back line speed is close to 0, which will cause damage to the tool, reduce its service life, and also affect the surface quality.
Utilizing the characteristics of five-axis machining that it can form a certain angle with the machined surface, shorter tools can be used to improve the rigidity of the tool, and the entire part can be processed quickly without the need for a second installation, and the surface quality of the part is also very good. good.
It can be seen from the above analysis that the application of five-axis machining technology to the production process of mold parts can not only improve the machining accuracy of parts, but also reduce the workload of part polishing and shorten the cycle of producing molds. However, in many aspects, processing The work of machine tools and programming puts forward new requirements on the relevant staff, requiring them to have a comprehensive understanding of the five-axis machining technology and be able to operate the corresponding software proficiently.
Five-axis machining technology has also developed rapidly under the development of mechanical equipment technology, and my country is currently paying more and more attention to training talents in the manufacturing field. These have laid the foundation for the extensive development and application of five-axis machining technology. In the near future, five Shaft machining technology is bound to be applied to more fields.
