What is Broaching?
The machining process known as broaching uses a toothed tool, called a broach, to remove material. A broach is similar in looks to a saw and contains three sections - roughing, semi-finishing and finishing. There are two main types of broaching:
Linear broaching - in which the broach is run linearly against a surface of the workpiece to effect the cut.
Rotary broaching - used in a lathe or screw machine, the broach is rotated and pressed into the workpiece to cut an axisymmetric shape.
Each tooth on the broach has a different rise, or height, that determines the amount of material removed from the material. The feed is built right into the tool and a sequence is created that makes it and all-in-one production process, reducing the margin of error.
When precision machining is required to get the job done, broaching is the go-to. Even though broaches can be expensive to produce, especially custom broaches, it is usually favored over other processes due to the efficiency and quality of the finished product.
