This article describes the Hex broach Tool Design Terms and uses. You’ll learn more about hexagonal broaches in this article, as well as the differences between hex and square broaches, and why hex broaches are more difficult to use. By the end of the article, you’ll know all you need to know about hexagonal broaches and their uses. The article concludes with some useful tips to help you use hexagonal broaches more effectively.
Design Terms for Broaching Tool
Hex broaching is a method of shaping a part with a hexagonal cross-section. The tool is made of a specialized metal and is used to shape parts of various sizes. This process is fast and accurate, and allows for a variety of different finishes. For this reason, it is important to know the proper design terms when purchasing a broaching tool. For example, a hexagonal cross-section is called a “hexagon.”
This tool is also called a wobble broach and a hex broaching tool. These terms likely refer to the hexagonal shape of the tool but “wobble broach” is not a misnomer. Some people confuse this tool with the polygon attachment, which is only used for external polygon shapes. If you’re not sure what these terms mean, here are some definitions of hexagonal broaching tools:
Hex broaching is also known as wobble broaching or rotary broaching. The tool is designed with a 1-degree offset along its longitudinal axis. This offset makes it possible to cut irregularly-shaped holes without creating a hole with a circular cross section. Typical applications for a rotary broaching tool include making parts for airplanes, automotive transmission gears, and other small components.
Uses for Hexagonal Broaches
The use of hexagonal broaches varies greatly. They are generally used for cutting holes that are hexagonal in shape. Hexagonal broaches are designed to cut through holes either manually or using an arbor press. These tools feature cutting teeth that are gradually larger on the outer periphery, giving them good rigidity, and cutting range. This design allows them to cut progressively deeper into the material being drilled.
The standard hexagon broach from Hassay Savage is a one-pass finish, which can be used with a vertical broaching machine or hydraulic press. If you need a custom-shaped hexagon broach, you can order one by submitting a print or sample of the part to be broached. Hassay Savage can make the necessary custom hexagon broaches for you if you need a specific size.
Conclusion of Hex Broach
The hex broach tool is similar to a saw in shape. The tool has three distinct sections – the cutting teeth, the slot sides, and the feed. The rise per tooth, or feed per step, determines the amount of material removed and the size of the chip. Broaches are used in a variety of applications, including metal working, precision manufacturing, and general fabrication. The hex shape allows the tool to be moved relative to the work piece.
Generally, the hex broach hole should be drilled at least 1.3 to 1.5 times the profile’s diameter. After broaching, the hole should be re-drilled with a smaller drill. In aerospace parts, it is not possible to drill within the broached wall, so counter-boring is required. Counter-boring allows for an extra step to keep the broach concentric as it enters the hole.
Another important feature is the face angle of the hex broach. This angle helps to create a sharper cutting edge and varies for different materials. External hex broaches are located on the outer flange and are held in place by two cap screws. The set screws should separate the body and shank by 3/16″ before the broach head is inserted. Alternatively, internal hex broaches have a recessed face, which means that the shank is surrounded by a cavity that allows for easy insertion of the shank.
