In large-series production involving metal cutting on workpieces with complex profiles, broaching is one of the most rational production processes. Provided that a high cutting capacity and precise reproducibility are required. The advantages lie in the technical principle: The profile is cut in one work step by a multi-toothed tool, the cutting edges of which lie one behind the other and are graduated by one cutting thickness each time. Here, the technically complex forward feed movement of other processes is replaced by graduation of the teeth cutting edges.

In the case of internal broaching, broaching is performed from an opening, whereas in surface broaching the work step is carried out on the outside of the workpiece. The broaching stroke is vertical or horizontal, and the cutting motion can be in a straight line or helical.
