Information

When the term “broaching” is used in the manufacturing industry, most think of conventional step broaching which involves pushing or pulling a toothed bar through a part on a press. It is a method that has been around since the beginning of (manufacturing) time. The problem with conventional broaching is that it has application limitations and cost/efficiency drawbacks. For example, conventional broaches can only be used in through-hole applications and must be performed as a secondary operation on a press. Also, costs and manufacturing lead times for conventional step broaches can be exorbitant. A newer manufacturing method called “rotary broaching” addresses these problems and can outperform conventional broaching in these areas.

Technical specifications

Working principle

Rotary broaching is a rapid machining method that cuts shapes into or onto a work piece. It involves using a broach, which is ground to the finished desired form, and a rotary broaching tool holder on a lathe, mill or other CNC machine. The rotary broaching tool holder has a free-rotating spindle on the front end, which holds the broach at a 1 degree angle (Diagram 1). The broach is driven by the work piece so no live tooling is needed. In a lathe, upon contact with the work piece, the broach and tool holder spindle will begin to rotate 1:1 with the work piece while the body of the tool holder is held stationary (Diagram 2). In a mill, the work piece is stationary, so the broach and tool holder spindle will remain stationary while the tool holder body rotates in the machine’s spindle (Diagram 3). The 1 degree angle that is built into the tool holder allows the broach to have only one point of engagement at a time. By only having one point of contact cutting at a time, very little thrust is required from the machine, which makes broaching possible to do on virtually any CNC machine. The whole process is completed in about the same amount of time as a drill cycle and creates a form within .0005” tolerance.

Applications

Any shop that has a CNC machine can utilize and benefit from rotary broaching. Whether machining a form into a blind or through hole, or cutting an external shape onto a part, the rotary broaching process is an excellent option to consider. Manufacturers using the rotary broaching process have been able to bring broaching back in house and drastically cut machining times and costs. In fact, many manufacturers are altering their machining methods to this technology from other more costly methods, such as milling, EDM wire cutting, or straight knurling. Some of the industries currently benefitting from rotary broaching are manufacturers of aerospace fasteners, medical implants, plumbing fixtures, automotive parts, and other general fasteners or fittings.
