Rotary Broaching processes can be performed on a Conventional Milling Machine or Lathe.

The process of Rotary Broaching is as follows: The Broach is held at a one degree angle to the workpiece in a Broach Holder, the workpiece is spun in the chuck, the Broach is driven towards the work piece, as the Broach engages with the workpiece, the Broach rotates with the workpiece, whilst simultaneously being driven towards the workpiece until the desired form is achieved.

Rotary Broaching produces polygons including; internal and external slots, keyways, splines.

More complex Broaching can be performed on a purpose built Linear Broaching Machine - see "Linear Broaching"
