Advantages Of Five-axis Five-linkage Machining Center

1. It can process continuous and smooth free-form surfaces that cannot be processed by ordinary three-axis or that are difficult to complete in one clamping. Such as the blades of engines and steam turbines, the propellers used in ships, and many shells and molds with special curved surfaces and complex cavities and hole positions, such as ordinary three-axis numerical control, due to the position of the tool relative to the workpiece. The attitude angle cannot be changed during the processing. When processing some complex free-form surfaces, interference or under-processing may occur (ie, it cannot be processed). When machining with a five-axis linkage machine tool, since the pose angle of the tool/workpiece can be adjusted at any time during the machining process, the interference of the tool and workpiece can be avoided and the entire machining can be completed in one clamping;

2. It can improve the machining accuracy, quality and efficiency of free-form surfaces in space. For example, when three-axis machine tools are used to process complex curved surfaces, ball-end milling cutters are often used. The ball-end milling cutters are formed by point contact, resulting in low cutting efficiency. Moreover, the position angle of the tool/workpiece cannot be adjusted during the machining process, which is generally difficult to guarantee. Use the best cutting point on the ball end mill (that is, the high point of the ball end line speed) for cutting, and there may be a situation where the cutting point falls on the center line of rotation where the ball end cutter line speed is equal to zero. CNC five-axis platform is processed by five-axis machine tool. Since the pose angle of the tool/workpiece can be adjusted at any time, it can not only avoid this situation, but also make full use of the best cutting point of the tool for cutting, or use The line contact forming helical end mill replaces the point contact forming ball end mill, and even milling can be performed by further optimizing the pose angle of the tool/workpiece, so as to obtain higher cutting speed and cutting line width, that is, to obtain Higher cutting efficiency and better machined surface quality.

3. The advantages of mold processing. In traditional mold processing, vertical machining centers are generally used to complete the milling of workpieces. With the continuous development of mold manufacturing technology, some weaknesses of the vertical machining center itself are becoming more and more obvious. Modern mold processing generally uses ball-end milling cutters. The benefits of ball-end milling cutters in mold processing are very obvious. However, if a vertical machining center is used, the linear speed of the bottom surface is zero, so the finish of the bottom surface is very poor. , If the CNC five-axis platform processing technology is used to process the mold, the above shortcomings can be overcome. Using the CNC five-axis platform to process the mold can quickly complete the mold processing, fast delivery, better guarantee the processing quality of the mold, make the mold processing easier, and make the mold modification easier.
