3 axis machining center and vertical machining center are widely used in traditional mold processing to complete the workpiece milling. With the development of mold manufacturing and processing technology, the ball end milling cutter commonly used in traditional mold processing has obvious advantages, but if vertical machining center is applied, its bottom linear speed is zero and its finish is poor, In this way, the weakness of traditional mold processing is gradually revealed. 5 axis machining can process different sides of the workpiece without changing the position of the workpiece on the machine tool, which can greatly improve the processing efficiency of prismatic parts. It can be used for deep cavity mold, side wall of mold, flat surface and irregular surface of mold, different geometry of mold and inclined hole on inclined plane of mold. It can reduce the processing time, improve the processing accuracy and improve the production efficiency.
In the mold processing, the use of 5 axis machining center can avoid the interference of cutting tools. It can process the complex parts which are difficult to be processed by ordinary 3-axis machine tools. For the machining of ruled surface mold, the side milling one tool forming technology can be used. The processing quality is good and the efficiency is high. For the three-dimensional surface, especially for the large and flat surface, it can be processed by the large diameter end milling cutter close to the large surface, the number of tool runs will be reduced, the residual height is small, and the processing efficiency and surface quality can be effectively improved. Multi process and multi surface processing can be carried out by clamping multiple space surfaces of the die at one time, which can improve the processing efficiency and the accuracy of each surface position.
When the 5 axis machining center is used to process the mold, the cutting tool can always be in the most effective cutting state for the workpiece. In some machining fields, large-size cutting tools can be used to avoid mutual interference. The rigidity of this kind of cutting tool is good, and the machining accuracy and efficiency can be improved.5 axis machining center can not only complete the task of complex workpiece machining, but also improve the machining efficiency and shorten the machining process.
The 5 axis machining center adopts the optimized and high rigidity structure design, with the machining accuracy of 0.003 mm and the positioning accuracy of 5 μ m. The repeat positioning accuracy is 3 μ m. It is suitable for the processing of key parts in energy, aviation, ship and military industries. It is the only way to solve the processing of impellers, blades, marine propellers, heavy generator rotors, steam turbine rotors, large diesel engine crankshafts and so on. It is no exaggeration to call it a "high-precision" precision processing plant.
Due to the homogenization of manufacturing industry, the competition is more and more fierce. Only the unique core technology, under the premise of ensuring quality to achieve higher production efficiency, or do other people can not high value-added products, can stand out. It is in this context that 5 axis machining center is favored by more and more manufacturers.
