At present, according to the configuration of coordinate axes, five-axis machining centers can basically be divided into two types of structures. One is a structure in which three linear axes (X/Y/Z) are used for tool movement and two additional rotary axes (A and C) are used for workpiece rotation and swing. The other is a structure in which one of the five coordinate axes (A) is set on the spindle head. The fork-shaped spindle head realizes the swing of the spindle tool, and the swing spindle head can also be firmly clamped to make it Position it at any position within the range of the swing angle.
Now the processing center has gradually become the most important equipment in the mechanical processing industry. It has a wide range of processing and a large amount of use. In recent years, there have been great developments in variety, performance and function. Variety: There are new vertical and horizontal five-axis linkage machining centers, which can be used for aviation and aerospace parts processing; there are high-performance machining centers dedicated to mold processing, integrated 3D CAD/CAM for ultra-precision machining of complex surfaces of molds; applicable It is a high-speed machining center for the processing of large quantities of parts for automobiles and motorcycles, with high production efficiency and flexibility. Performance: Electric spindles with more than ten thousand revolutions are generally used, up to 60,000 to 100,000 revolutions; the application of linear motors makes the machine tool acceleration reach 3-5g; the implementation of ISO/VDI testing standards promotes manufacturers to improve the two-way positioning of machining centers Accuracy. Function: Combines the composite functions of laser processing, and is structurally suitable for forming a modular manufacturing cell (FMC) and a flexible production line (FMS), and has the functions of electromechanical and communication integration.
The price of a five-axis machining center is much higher than that of a three-axis machining center. The price of a five-axis machining center is compared with a three-axis machining center. The price of a five-axis machining center is about 50% higher than that of a three-axis machining center. Although the price of a five-axis machining center is high, this high-end machine tool is particularly suitable for machining molds with complex geometric shapes. When the five-axis machining center is processing deeper and steeper cavities, the additional rotation and swing of the workpiece or spindle head can create the best process conditions for the processing of end mills, and avoid cutting tools, tool holders, and cavity walls. Collision occurs, reducing the jitter of the tool during machining and the risk of tool damage, thereby helping to improve the surface quality of the mold, the processing efficiency and the durability of the tool. When purchasing a machining center, whether to choose a three-axis machining center or a five-axis machining center should be determined according to the complexity and accuracy of the mold cavity geometry.
It will be a universal equipment that can be used for turning, milling, grinding, laser processing, etc., and become a true machining center. From the feeding of materials to the output of finished products, rough and finishing, hardening treatment, super finishing, automatic detection and automatic correction will be omnipotent. The equipment will attach importance to environmental protection and energy conservation, showing signs of green manufacturing. The IT functions characteristic of the 21st century era are absolutely indispensable. The equipment will exchange information with the outside world through the network and obtain the latest technological achievements. Human wisdom will be fully demonstrated in the high-tech product processing center.
