[0002] The universal angle head, also known as the universal milling head or universal milling head, is a machine tool accessory. After the milling head is installed on the machine tool, the rotation center line of the tool can be at an angle to the rotation center line of the spindle to process the workpiece. It is originally produced in Europe and is now widely used in various fields of mechanical processing such as aviation, automobiles, and molds. The use of the milling head can increase the processing range and adaptability of the machine tool without changing the structure of the machine tool, making it possible to achieve some processing that is difficult to complete with traditional methods, and can reduce repeated clamping of the workpiece, thereby improving processing accuracy and efficiency.
