Industry Information
View A Video on Broaching- A Quick Introduction

Broaching is an efficient, cost effective method of precision machining that can be performed on an external surface (round, flat or contoured) or the internal part of a shape or form. It is considered a metal removal service, and almost any material, from ferrous and nonferrous metals to plastic materials and wood are able to be cut through broaching, although softer metals are by far the most common material.

Various broaching methods are performed in broaching job shops to cut internal splines, gears and sprockets, as well as keyways, slots and serrations on the surface of a work-piece. These products are fabricated in high volumes, a process called production broaching, which takes place in a facility that specializes in broached parts. While broaching machines are specialized and have somewhat limited ranges of abilities, there are many different kinds that do different kinds of broaching, including spline cutting, keyway broaching using a keyseater machine and gear hobbing. Broaching machines work on the outside of a work-piece or create holes by internal broaching, which reaches all the way through the material. They are either horizontal or vertical machines, depending on the size of the work-piece and the involvement of the manual worker. Vertical broaching is used for higher volumes of products. The holes and grooves that are made with a spline shaft, which contains a series of successively larger teeth that are strong enough to cut through metals, may reach all the way through the work-piece, forming a hole, or make shallow indents that blind broaching produces. Rotary broaching is a popular method that spins the broach tool at high rotations and pushes or pulls it through the work-piece. Pot broaching inverses the machinery movements-the broach tool stays stationary while the work-piece moves through the broaching machine.


The broaching process produces many different parts and products, mostly for use within the industrial sector, and usually made of softer metals like aluminum, brass and copper, although harder metals like steel grades and other materials including plastic and wood are also able to be broached. The most common broached products are gears. A broaching process called gear hobbing forms their shape by externally broaching the grooves on the gear's external surface. Sprockets, pulleys, the heads and threading on fasteners like screws, nuts and bolts, smaller wheels, gun components, industrial machinery parts, tools like wrenches and bushings all get their shape from the broaching process, which doesn't generate or require any heat and therefore is less prone to error. During the broaching process, machines such as automatic lathes, CNC Swiss lathes and rotary transfer machines are used to push or pull a broaching tool with cutting teeth through or over a work-piece. The only limit to the process is the length and width of the part that is being machined.

The most common form of broaching services is done using hydraulic driven machines, since they require a large amount of power in order to operate continuously. There are three main methods to forming the holes and indents in the work-piece, including pull broaching, push broaching and pot broaching. When the broach cutting tool is pulled through the part in a single pass, this process is called pull broaching. The second most common type of broaching services used is push broaching. Broaching job shops most often utilize this service on short run jobs using a hydraulic press, or more commonly, a hand operated arbor press. Pot broaching, on the other hand, moves inversely-while the broaching tool remains stationary, the work-piece is pushed through it inside a hollow casing shaped like a pot. Broaching job shops can also perform broaching on a lathe, which spins at a high rotation. During rotary broaching, the tool must be held at a 1° angle to the work-piece. The cutting face of the broach should be positioned as close to the centerline of the work-piece as possible. The tool and part are stationary while the broach holder spins on a spindle. As the broach tool and the part come into contact, the tool moves in a "wobble" motion; thus, another name for this process is wobble broaching.

The entire broaching process takes a matter of seconds, and is fully automated. High production runs are possible, making broaching cost efficient, economical and fast. Broaching has many advantages, including high productivity, economical operation, accurate cuts over large runs, close tolerances, versatility and smooth finishes. Chips tend to accumulate in the broaching hole. Therefore they must be cleared periodically so that they do not cause damage to the broach tool. Also, the hole must be drilled as deep as possible to allow room for the chips to accumulate. Sometimes a pressure relief vent on the broach tool is necessary when broaching a tight hole if air, oil and coolant cannot escape. If enough hydraulic pressure is generated, the broach will be pushed back and could cause damage to the machine. A ventilation hole on the tool prevents this occurrence.
