[0002] A five-axis head refers to a machine tool accessory that can move in multiple axes. It achieves complex part processing by controlling the movement of different axes. The five-axis head can move freely in five axes, and the tool can contact the workpiece at any angle, thereby achieving processing of complex shapes. It also has the characteristics of high precision and high rigidity, which can ensure the stability and accuracy of the processing process, greatly improving processing efficiency and processing quality. The five-axis head is widely used in five-axis machining centers, milling machines, drilling machines and other equipment, and plays an important role in aerospace, automobile manufacturing, mold manufacturing and other fields.
