Drejning og fræsning kombineret bearbejdning af cylindriske dele

Cylindrical parts with milling features on compound corners or multiple faces are very common. A factory that provides services for large-scale equipment and oil companies, and produces parts that require precise 5-axis contour machining and finishing. B-axis machine tools are usually used to manufacture slotted shafts, and to machine grooves and cuts on compound angles. Such factories also use B-axis machine tools to process complex polyhedrons, such as tool bodies and tool holders.

The size of the parts processed by the B-axis machine tool is various. It can process watch gears as small as 0.04 tommer i diameter, or metal castings as large as 20 tommer i diameter.

For at imødekomme kundernes forskellige bearbejdningsbehov, Methods Machine Tool Company leverer to modeller af Nakamura Tome-maskiner udstyret med B-akse. STW-40 værktøjsmaskinen med en standard 40-stations automatisk værktøjsskifter er designet til at bearbejde store og tunge dele. Såsom: støbegods og smedegods, og kan behandle emner op til 17 tommer i diameter. Imidlertid, som svar på kundernes behov, Metoder Machine Tool Company kan nu levere en mindre model af B-akse værktøjsmaskiner, nemlig NTJ (B-akse tårn). The weight of this machine is only about half of the STW-40. The advantage is that it occupies a small area and is easy to maintain and operate compared to large-sized machine tools. NTJ is most suitable for machining smaller B-axis parts, such as joint tools up to 8 tommer i diameter.

Both of these models are equipped with a bar feed function, so it is possible to feed raw materials to the machine tool in a continuous flow method, and then perform B-axis cutting. Hvis det er nødvendigt, this processing can also be performed on part features equipped with compound angles. When evaluating parts and bar feed options, the factory should consider the size of the raw material. Although a large B-axis machine tool equipped with a bar feed function can handle larger bars, it is impractical to always load such specifications into the machine tool. Because bars are generally relatively long (op til 12 feet is not uncommon), human or robot lifting may be too heavy. Large materials are also difficult to cut, especially in cutting bars.
