At present, there are many methods and equipment used in machining centers, and the CNC four-axis machining center is a relatively common machining method. At first, three-axis machining was generally used. In terms of performance, function and adaptability, four-axis machining is better.
Although cnc four-axis machining is very common in the industry, there is not much theoretical data in the process of development. Therefore, various problems are often encountered in actual applications, such as tool problems. It will also affect the efficiency of the overall equipment.
Four-axis machining centers are mainly divided into two types: horizontal and vertical. The two types have their own characteristics. Generally, if the application is horizontal, you can add a B axis to the Y axis. The programming method is similar to that of the 3 axis; it can rotate 4 sides to achieve the highest accuracy requirements. Compared with the three-axis, the four-axis is generally used for the needs that cannot be processed by the three-axis machine tool, such as the depth and angle limit can not be processed by the parts, common fan blades, worms and other products.
In fact, many CNC four-axis machining centers evolved from CNC milling machines. The difference between the two is whether they have the ability to automatically exchange machining tools. The former can well complete automatic exchange, have automatic tool change in one clamping, and complete a variety of processing functions. In addition, the four-axis machining center can also complete the linkage control of more than three axes, which can better process complex surface equipment.
To sum up, the four-axis machining center is a kind of high-efficiency and high-precision CNC machine tool. It only needs one clamping to complete the processing of multiple processes. It also has complete tool functions and automatic tool change functions.
