Description

Technical Field

The invention relates to a processing device, in particular to a novel angle head tooling processing device.

Background technique

Angle heads are widely and frequently used in the field of mechanical processing. Angle heads are a kind of machine tool accessories. After the machine tool is equipped with the angle head, the rotation centerline of the tool can be at an angle to the rotation centerline of the spindle to process the workpiece. Originated in Europe, it is now widely used in various fields of mechanical processing such as aviation, automobiles, and molds. The use of angle heads 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 workpieces, thereby improving processing accuracy and efficiency.
