For the arrangement of the five axes of the machining center, we are talking about the vertical machining center here, and then the whole story can be divided into two parts. The first three axes are the X, Y, and Z axes. They are usually designed and activated and moved on the superstructure of the machining center. They are conventional milling structures.
At the beginning of the 20th century, we knew there was no machining center. Another substructure contains two other axes, namely A and B, or some axes may be B and C or A and C axes. This is usually a rotary table, cradle bed, and other mechanical structures similar to the lower structure. They can be synchronized with the superstructure (X, Y and Z axis) under the integrated cutting path plan (also called CNC control system) of computer programming.
In today's smart manufacturing, customers' order requests are usually small in number but wide in variety. However, with higher processing capacity and higher durability of the processing center, it has become one of the most effective processing methods for metal processing solutions in modern industry. The 5 axis machining center evolved from its 3-axis ancestor, and it has been widely used in manufacturing for decades.
In recent years, machining centers have been designed to have at least three axes, namely x, y, and z. Similarly, for vertical and horizontal models, anyone can be equipped with other shafts, so that the machine has a 5-axis capability. By designing two additional axes on the rotary table, the x, y, and z axes can be moved to two new working dimensions, thereby enabling possible cutting processes at multiple angles.
As we mentioned above, there are many operations that can use 5 axis machines, which can also save a lot of workers time and improve their current processing procedures. There are different types of these machine centers that can meet the needs of the evolving manufacturing industry. The main difference from the 5-axis CNC machine is the arrangement of the rotary axis. The second type of 5-axis composition of the machining center is the swing head type, which alone can achieve most machining angles and is compared with other 5-axis compositions. This type of machine is considered to be the most convenient; a single shaking head can complete all tools at once.
In addition to the swing head and the upper and lower structure, there are four-plus-one type 5 axis machining centers. The machining center contains four moving axes in the upper structure, one of which is used for the lower structure. In other words, it is designed under the structure of a four-axis machine. It is based on an additional axis and provides the metalworking operator with an additional axis compared to the existing four axes.
In order to obtain better cutting rigidity, the double column structure and 5-axis function are one of the very practical solutions to solve the problem of machining vibration and at the same time improve the accuracy. Double column 5 axis machining centers are usually divided into two types: fixed columns or moving columns.
For fixed columns, this design leaves both columns in place and cannot be moved. The latter allows the possibility of another axis, greatly improving the convenience of processing. The CNC 5-axis double-column machining center is a highly developed machine that can handle a variety of machining tasks. After developing 5 axes, the development of this particular type of machine tool is progressing smoothly in the industry. After that, machining centers were widely used in various industries. It has played an important role in a wide range of industrial applications, especially in the aerospace, automotive and shipbuilding industries, where heavy cutting and complex angles are the basic basis for machining tasks.
This article has introduced the arrangement of five axes in the machining center, especially the five axis machining center model of computer programming. The model is controlled by the CNC control system during the entire process. Obviously the industrial trend of complex machining and high standard rigidity has arrived, and all milling-based machines on the production line must be able to handle the task. Regardless of the layout, as long as the processing requirements are met, the manufacturer can accept the 5 axis machine. Most importantly, customers and end users can also accept.
