Turning and milling combined processing of impeller blades

Blade processing, as a typical part type of five-coordinate processing, has huge market demand. In fact, most of these parts can be completed on turning and milling machining centers. For some turning and milling equipment with B-axis linkage, the types of parts that can be processed will be wider. This type of equipment not only has turning functions, but can also complete three- to five-coordinate linkage milling work.

With the development of machine tool hardware, the rigidity of machine tools has been significantly improved, and roughing and finishing machining can be completed at one time. From a technological perspective, turn-milling composite equipment has the advantages of simple clamping and positioning of parts, various roughing methods, and convenient chip removal. . At the same time, the price of turning and milling equipment is getting closer and closer to that of multi-axis milling and machining centers of the same grade. Therefore, it is gradually becoming a reality to complete the processing of impeller blades on turning and milling composite equipment.

For ordinary C&Y turning and milling equipment, blade processing can be completed through C-axis linkage. This type of control system is actually a three-axis control system. To complete the surface processing through XZC three-axis linkage, there is no need to invest more in machine tools. You only need to choose a CAM software that can provide this function. as the picture shows:


Lansheng provides Japan’s Okuma MACTURN series turning and milling compound CNC machine tools, a new compound turning and milling center that integrates machining centers and turning centers. There are three models in total: MACTURN250, MACTURN350 and MACTURN550. It can process worms, blades, spirals, cams, eccentrics and bevels, etc., and is suitable for powerful composite precision machining of complex-shaped parts such as aircraft, automobiles, engines, pump bodies, molds, and cutting tools. Has the following performance characteristics:

▪The machine tool has the main spindle, sub-spindle and tool holder of the lathe.

▪It also has the X, Y, Z, B axes of the machining center and an automatic tool changer.

▪This machine tool has nine-axis control and can perform four-axis simultaneous and efficient processing. The X, Y and Z three-axis linear guides adopt roller transmission.

▪The processing capacity of turning can reach: 2.5mm2, milling can reach: 68cm3/min, and the actual roundness can reach: 0.3μm. Y-axis travel: ≥160mm. The ATC tool magazine has a large capacity, high power for power tools, and can be equipped with a lower tool rest with 12 tool positions.
