Broaching Job Shops Industry Information

Broaching Job Shops

Broaching job shops are facilities that specialize in the metal removal service known as broaching, which creates cut outs, holes, and profiles in metal performs called workpieces. Most broached products are produced in these facilities, when metal workpieces are broached internally or externally in high runs and large volumes. The broaching process is cost-effective, easy, and efficient because it is done with automated or CNC operated machinery that is either horizontal or vertical in orientation.

Applications of Broaching

The production broaching done at broaching job shops is an exceedingly positive broaching characteristic, since many workpieces are machined at once and this process takes only seconds to complete. Since broaching requires no secondary operations and the machining process is so short, producing high volumes of industrial products like pulleys, gears, sprockets, and the threading on screws takes little time. Broaching machines are considered special purpose machinery because they are confined to very limited capabilities; many can only produce one or two different product designs. For this reason, facilities that use broaching machines usually specialize in a certain type of broaching, including blind broaching, external broaching, or rotary broaching.

These processes machine workpieces, usually made out of softer metals like aluminum, copper, and brass, that when finished are used within the automotive, machinery, aerospace, commercial, and military industries. Broaching machines produce several different shapes in metal, which alter the surface or are drilled straight through. Types of shapes created by broaching machines include hexagonal, square, round, slots, splines, and the most common cut, a hole with a keyhole-shaped profile called a keyway.

Process of Broaching

Broaching is accomplished several different ways, including pull and push broaching. When a workpiece is pull broached, the broach tool, which is long and thin with successively larger teeth, is pulled through the part in a continuous motion. It can also be pushed through. Rotary broaching is done on a lathe and the tool revolves at high speeds. Some broaching processes like pot broaching reverse the motion and, while the tool remains stationary, the workpiece is moved with high force through it inside of a hollow housing called a pot. Larger broaching job shops contain several of these machines, which are also able to stamp, cast, and forge the workpieces. While there are many different methods and styles of broaching, the main idea remains constant. Every broaching machine, whether vertical or horizontal, contains one or more broach tools that contain teeth that cut out pieces of metal on the interior or exterior of the metal workpiece. They are automated and sometimes even part of a conveyor line system.

Types of Broaches Utilized at Broaching Job Shops

When manufacturers need to rapidly produce large volumes of parts with specific shapes, the preferred machining process is broaching. However, broaching is so specialized that broaching job shops now offer different broaches to machine work pieces. Each broach tool has its own definite arrangement of multiple teeth to machine parts—therefore, different broaches are developed for different applications. Broaches generally fall into two major categories: push broaches and pull broaches. Broaches are then additionally categorized as either internal or external.

Here are the major types of broaches and their differentiators:

Push Broach
Pushed through soft work pieces to machine a part, either with an arbor press or with a hydraulic press, depending on the application. A manual arbor press is used for low volume. However, when the volume of parts to be broached is large, a mechanized press is used. A push broach is typically short, as it undergoes compression to shape parts. A long push broach will either break or buckle under heavy loads.
Pull Broach
This type of broach is always pulled by a machine, either up and down or horizontally. Typically, pull broaches are flat or nearly flat, and they are used to flatten out the cylinder blocks and heads of vehicles. To a machine using this type of broach, a part is rigidly mounted and the broach is pulled across to give it shape.
Internal Broaches
Broaches are categorized as internal based on their use, as they machine parts from the inside. Internal broaches include a hole through which they either are pulled or pushed in order to machine parts from the inside. Types of machines that use internal broaching range from automated and verticals units to pull-type horizontal units.
Internal broaches have applications in keyway making and burnishing. For making keyways in parts and tools, keyway broaching is employed, which includes a flat bar with an arraignment of cutting teeth. To guide a keyway broach while machining, a slotted bushing or horns, which attach to the hole, is required. However, when parts of similar diameter and keyway size are to be machined, horns or bushings are not required. Burnishers are specialized broaches that do not cut material but polish instead. When accuracy is critical, burnishing broaches are used, and they work as a push broach. There is one more type of internal broach called shell broach, which is used for roughing and finishing purposes.
External Broaches
This type of broach is utilized when material has to be removed from the external surface. External broaches are also known as surface broaches. To machine work pieces, an external broach with a combination of teeth is passed over the machine surface. Inversely, sometimes the workpiece itself is moved against the teeth of an external broach to give the part a flat or contoured surface. External broaches come in many types that differ in shape based on the manufacturing requirement. Inserts or indexable tool bits are used with external broaches with the help of a broach holder or sub holder that is mounted on the machine. Blind broaching is a common example of external broaching; it occurs when indents and shapes are machined on metal workpieces.
