5 axis mill turn machines, or 5 axis turn mills, are popular multi-function machine tool models in the industrial sector. Because 5 axis milling turning functionality is becoming more complicated, it is now harder to define clearly whether a unit belongs to the mill turn machine, milling center, or machining center category. But one thing they all have in common is that additional yet powerful accessories are added to these models to enhance functionality.
These milling machines are able to perform turning as well, and the advanced units are even able to perform boring and tapping. We’ll elaborate more about the 5 axis mill turn machines as well as other varieties.
A 5 axis machine, whether it is a 5 axis machining center or turning center, it must be controlled by a computer numerical system (CNC) because only then the axes are able to work together synchronically with the existing features of the mill turn machine. This type of machine can collectively be referred to as the CNC milling center. It is a machine tool that utilizes turning method as a basis to rotate a work piece on an axis of rotation in order to perform various machining operations such as cutting, drilling, deformation, and facing. Other machining processes involving turning are also conducted with cutting tools that are applied to the work piece to create an object with symmetrical shape. The moving axis is driven by the primary spindle.
Some may wonder why mill and turn are integrated together. In the early days, turning is conducted exclusively on a turning machine. In other words, it was a simple purpose lathe per se. But when other jobs, like milling for instance, were to be performed, people had to move the same work piece over to another work table because milling could only be done on a dedicated milling machine in the past. These two types of cutting methods were rarely integrated due to the barriers in technology then. But now since the motor and power issues are taken care of, the integration become not only natural, but also mandatory for most manufacturers.
Speaking of the multiple axis mechanism, machining centers immediately come to mind for industrial insiders. Machining center is one of the most efficient ways for metalworking solution in the industry. There are mainly three types of construction methods that constitute a 5 axis machine. The same principle also applies to the 5 axis mill turn models.
The first type is the swing head. The swing head is able to achieve most processing angles. This kind of machine is considered just as convenient as other 5 axis models, such as four plus one, and three plus two machining centers. However, the latter two are more advantageous due to the existing three-axis arrangement. Conventional machining centers are designed at least with three axes, namely, X, Y, and Z, and for both vertical and horizontal models, and both type can be supplemented with other axes. Equipping the three additional axes can make the working zone much wider and deeper.
Working table in this type of model becomes another axis or even two axes because the table may be designed to be rotational, while some may even install another track under the rotational work table to allow it to move. The movement is synchronized. With the other additional two axes, the X, Y, and Z axis can move onto two new working dimensions such as A and B axis. This permits multiple angles of possible cutting processes. This situation is the same with the four plus one structure as well.
Not all the mill turn with multiple axes can deal with all challenges. For instance, it may be difficult to work on a work piece that is oversized. If the size of the material is larger than that of the work table, the machining would cause too much vibration to the machine body, thus deteriorating the precision frame of the machining centers. This is not an acceptable situation for both manufacturers and the relative production lines. Therefore, manufacturers may add some other structural designs onto the body to enhance rigidity for the milling process.
Furthermore, regarding its milling capacity, this machining method could go in different directions. In the metalworking sector, milling process of mill turn centers covers a wide variety of various operations. This scale ranges a wide scale from single tiny parts to heavy and large milling operation tasks, achieving significant industrial achievement for the business owners.
