Although CNC 4 axis machining is now very common in the industry, there is not much theoretical data in the development process, so we often encounter various problems in actual application, such as the problem of tools, which will also affect the efficiency of the overall equipment.
4 axis machining centers are mainly divided into two types: horizontal and vertical. The two types have their own characteristics. Generally, if the horizontal type is used, a B axis can be added 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. Compared with three-axis machines, 4 axis machines are generally used for the needs that three-axis machine tools cannot process. For example, the depth and angle limits cannot process parts, common fan blades, worms and other products.
In fact, many CNC 4 axis machining centers evolved from CNC milling machines. The difference between them is whether they have the ability to automatically exchange machining tools. The former can well complete automatic exchange, with automatic tool change in one clamping, and complete multiple processing functions. In addition, the 4 axis machining center can also complete linkage control of more than 3 axes, which can better process equipment with complex surfaces.
To sum up, the 4 axis machining center is an efficient and high-precision CNC machine. It can complete multiple processes with only one clamping. It also has perfect tool function and automatic tool change function.
