Milling classification steps of large five-axis machining center

       What are the milling classification steps for a large five-axis machining center? Milling of a large five-axis machining center refers to the use of a rotating multi-blade tool to cut the workpiece during the processing of the workpiece to achieve the process of making the finished workpiece. It is one of the current high-efficiency processing methods, which is more efficient than the method of mold casting. accurate.

       At present, the application of milling machine tools include vertical milling machines, horizontal milling machines, and large gantry milling machines for the production of large workpieces. The milling machine tools include not only ordinary mechanical machine tools, but also high-performance, highly automated CNC machine tools. Their similarities are the cutting processing using a rotating milling cutter as a cutting tool.

       For the milling tool of the five-axis machining center, the rotation during work and the movement of the workpiece (the workpiece can also be fixed), and the rotating tool must also move at the same time to achieve the effect of five-axis simultaneous machining. So, why should the milling of the five-axis machining center be grouped, semi-finished and finished? First of all, rough milling and semi-finish milling are irreplaceable steps in workpiece processing. Secondly, the forging and casting process makes it impossible for the blank to directly control the finishing milling allowance of the workpiece, and it cannot meet the process requirements with one milling. At least one more pre-milling is required. Then, rough milling removes most of the blank margin, and semi-finish milling can control the margin of fine milling. And finishing milling to complete the final size control and surface finish, the three are indispensable.
