First, it can be processed that the three -axis cannot be processed or it is difficult to install the continuous and smooth free surface of processing at a time. Such as the blades of aviation engines and steam turbines, spiral pusher used by ships, and many shells and molds with special curved surfaces and complex cavity, such as ordinary tri -axis, because their tools are relative to the workpiece because of the workpiece. The corner of the position cannot be changed during processing. When processing certain complex and free curved surfaces, interference or machining may be generated (that is, the processing is not processed). When processing with a five -axis linkage machine tool, because the corner of the tool/workpiece can be adjusted at any time during processing, you can avoid the interference of the tool workpiece and complete the entire processing at a time;
Second, it can improve the processing accuracy, quality and efficiency of the free curved surface. For example, when the three -axis machine tool is processed complex curved surface, the ball head milling cutter is mostly used. The ball head milling cutter is formed with point contact, the cutting efficiency is low, and the corner of the tool/workpiece position cannot be adjusted during the processing process. Generally, it is difficult to ensure that it is difficult to guarantee The best cutting point (that is, the highest point speed of the ball head) on the ball head milling cutter, and the cut point falls on the center line of the center line of the spinning center of the ball header. The use of a five -axis machine tool is processed. Because the corner of the tool/workpiece is adjusted at any time, it can not only avoid this situation, but also always use the best cutting point of the knife to cut it, or use the line to contact the forming form. The spiral milling cutter is used to replace the point -to -shaped ball head milling cutter, and can even be used by further optimizing the corner of the position of the tool/workpiece, so as to obtain a higher cutting speed and width of the cutting line, that is, to get higher cutting Efficiency and better processing surface quality.
Third, the advantages of mold processing. In traditional mold processing, the milling processing of the workpiece is generally used to complete the workpiece. With the continuous development of mold manufacturing technology, some of the weaknesses of the vertical processing center itself have become more and more obvious. Modern mold processing generally uses the ball head milling cutter to process. The benefits of the ball head and milling cutter are very obvious in mold processing, but if the bottom surface is used, the line speed of the bottom surface is zero, so the smoothness of the bottom surface is very poor. If the four or five -axis connected machine tool processing technical processing molds can be used to overcome the above shortcomings. The use of five -axis linkage mold processing molds can quickly complete the mold processing, delivery quickly, better ensure the processing quality of the mold, make the mold processing easier, and make the mold modification easier.
