Broaching is a type of machining process in which the tool is pulled or pressed along the workpiece for chipping, and in some cases the tool is fixed and the workpiece is pulled or pressed by the tool.
Broaching is a unique process with very high efficiency and one of the most productive manufacturing processes. Broaching is a deformable process based on the cut. In the Broaching method, a number of cutting edges are created on a shaft. These cutting edges enter the workpiece and perform the cutting operation. These edges determine the thickness of the chip.
This method is used to pay for a thousand thorn holes and flat surfaces. In drilling operations, both roughing and polishing operations are done in one step of passing the needle, which causes closed tolerances in this operation. But with increasing accuracy, the cost of producing tools increases much more.
