Broaching is a machining technique used to remove unwanted metal from a workpiece. Flat, round, and contoured surfaces can all be machined using this kind of manufacturing process, as well as internal and external surfaces.What is broaching in machining?
Broaching is a machining process that uses a toothed tool, called a broach, to remove material. There are two main types of broaching: linear and rotary. In linear broaching, which is the more common process, the broach is run linearly against a surface of the workpiece to effect the cut.How does rotary broaching work?
Rotary broaching is a metalworking technique used to cut shapes like hexagons and squares, both internally and externally. In this process, a technician mounts a cutting head into a tool holder and advances it into a component like a bolt to cut it. The tool holder rotates, allowing the cutting head to dig in and produce the desired shape.What is a rotary broach?
Rotary broaching is the process by which a non-round shape is produced on either the inside or outside of a part. Rotary broaching works because the head of the broaching holder is offset from the centerline of the shank on a 1° angle (see Video 1).
