What is Broaching?

Broaching is a machining process that involves removing material from a workpiece using a specially designed tool called a broach. In the context of the gear industry, broaching is a versatile method employed to produce gears with precision and consistency. The process is known for its efficiency in creating complex shapes and tight tolerances.

The Broaching Process

Imagine a key sliding effortlessly into a lock, ensuring a perfect fit. Broaching operates on a similar principle but on a larger and more intricate scale. Gears are shaped by the linear motion of the broach, which features multiple cutting teeth. As the broach moves across the workpiece, it gradually removes material, leaving behind a precisely cut gear profile.
