The Concept of Broaching
Broaching is a machining process that involves cutting or removing material from a workpiece using a toothed tool called a broach. The broach is a long, narrow tool with multiple teeth that progressively increase in size. As the broach is pushed or pulled through the workpiece, it removes material in a controlled manner, creating precise internal or external profiles. The process is known for its accuracy and repeatability.
Types of Broaching Machines
Broaching machines come in various types, each designed for specific applications. The most common types include:
Horizontal Broaching Machine: This machine is ideal for producing external profiles, such as keyways and splines, on flat workpieces. It operates with a horizontal orientation, making it suitable for parts like gears and shafts.
Vertical Broaching Machine: Vertical broaching machines are used for internal broaching operations. They are capable of creating internal keyways, holes, and other intricate shapes within cylindrical workpieces.
Surface Broaching Machine: Surface broaching machines are designed to create flat or contoured surfaces on workpieces. They are commonly used in applications where a smooth and precise finish is essential.
