Regarding five-axis linkage CNC machining, many people have no impression of it, mainly because it is relatively unpopular and rarely appears in our lives, so it is normal to not understand it. It is a machine tool with high technological content and high precision specially used for processing complex curved surfaces. We can also understand it as five coordinate axes on a machine tool, which can coordinate the movement at the same time for processing under control. Its characteristics are also quite special. One is that it cannot be processed by a three-axis machining machine. If it is really necessary, it can be clamped too long. The second is that it can effectively improve the accuracy, quality and efficiency of free space surfaces.

Five-axis linkage CNC machining is very different from three-axis. Five-axis has two more rotation axes than three-axis. The five-axis coordinates have always been a puzzle in people's minds. What do they represent? In fact, this is very simple. The Z axis represents the direction of the machine tool spindle axis, and the direction perpendicular to the rotation axis of the workpiece in the horizontal plane is selected as the X axis. Generally, the direction away from the spindle axis is the positive direction.

The structural form of five-axis linkage is still relatively complex. For example, let's take AB as an example. On top of the B-axis rotary table, there is an A-axis rotary table, a small turbine, an impeller, and a small compact mold. When processing A and B, B and C in a turn-and-swing mode, the accuracy will be higher, and the machine will be stronger just after waking up. Generally, the larger the workbench, the greater the strength. This mode is generally only suitable for large-scale workpiece processing scenes.
