A horizontal broaching machine is most commonly used for internal broaching, where a tool is pulled through a pre-existing hole to create precise, complex internal shapes. The horizontal orientation is ideal for longer parts and operations that require a long stroke.

Common applications

• Keyways: Creating a keyway, which is a slot cut into the bore of a gear, pulley, or other part to hold a key for transmitting torque to a shaft.
• Splines: Cutting internal splines or grooves inside a hub or gear to provide a secure and robust mechanical connection with a shaft.
• Slots: Machining single or multiple slots for specific component designs.
• Internal profiles: Producing round or irregularly shaped holes with high dimensional accuracy and surface finish. This can include squares, hexagons, and other complex contours.
• Long workpieces: Broaching long parts such as shafts and rods that are too cumbersome for vertical machines.
