You have probably seen different hex broaches at work. Some are surface-mounted, while others are keyway-mounted. Whatever your needs, you’ll find the right tool for the job. These tools all have their own advantages and disadvantages, but they all have some basic qualities in common. Below, we’ll discuss five of the most common types of hex broach and the differences between them.
Surface broaches
The hex broaches used in industrial settings are of two types: deep and shallow. Deep hex broaches are used in precision-machining applications, while shallow hex broaches are used in general-purpose applications. Both types of hex broaches can be used on the same work piece, though surface hex broaches are more common. These two types of hex broaches are similar to each other.
While a deep hex broach can be used to drill holes in a variety of materials, it is not a good choice for a tight fit. Broaching tools must be aligned properly to avoid drifting and breaking. They should also be supported properly so that two teeth are engaged at all times. Lubrication is essential to minimize friction and clear chips. Some manufacturers have a pressure relief vent in their broach to allow the oil to escape.
Both types of hex broaches are commonly used in the push and rotary broaching process. While rotary hex broaches are generally faster, they require less pressure than their three-point cousins. For rotary broaching, however, hex broaches require going to the full depth three times after indexing. Consequently, they may exhibit a deflection on the second and third passes, but are generally used for deeper broaching processes.
Index broaches
In contrast to full-form internal rotary broaching, an index broaching uses a stationary spindle to produce a partial shape of the desired part. The machine tool generates the part by imprinting the form to the proper depth, and then the part is indexed to create the full form. Index broaching is most efficient at hole diameters less than 3/8 inch. Once the part is indexed, the drilling or boring bar can reenter the hole and finish the cut.
There are five common types of index broaches. Each of these can cut a keyway-shaped hole in a solid material. When choosing the appropriate index broach for a specific task, consider the type of material to be cut. A standard square index broach will cost less than a specially-formed keyway broach. In addition, it will be less expensive to buy a keyway broach, which will be more difficult to work with.
The most common types of index broaches are: solid pull, shell pull, and insert pull. They all have different shapes and geometries, but they all share a basic design. Internal-cut index broaches are the most common, while external-cut index broaches are the most expensive. In addition to internal and external cuts, there are many other types available. Choose the best one for the job and your budget.
Keyway broaches
Hex keys are the most common use of keyway hex broaches. These tools are used to create keyways in different kinds of shafts. They are made from various materials and they are generally made of carbon steel or stainless steel. There are two main types of keyway hex broaches: manual and power. Both types are suitable for the same task. Each type has its own pros and cons.
Keyway broaches are tools used to make precise holes in the work piece. They are bar-shaped and feature cutting teeth. Their larger teeth make it easier to remove material from a work piece. They are also suited for producing a polished finish. And, if you are looking for more efficient tools for cutting keyways, you can choose the ones that are self-supporting. The types of keyway hex broaches available can help you save time and money.
The main advantage of a broach is that it comes with all the features of a shape. Therefore, it doesn’t require complicated motions or skilled labor. It is, essentially, a set of single-point cutting tools that are installed into a machine. This way, multiple cuts are performed one after the other. This feature is reminiscent of multiple passes on a shaper. If you seek Hexagon Broaches & Hexagonal Broaches consult with Somma Tool for further information.
