A CNC (Computer Numerical Control) broaching machine is a specialized machine tool that is used for cutting internal or external keyways and other types of grooves or slots in workpieces. It typically consists of a broach, which is a long, multi-toothed cutting tool, and a broaching machine, which holds and moves the broach.

The broaching machine typically consists of a bed, a slide, and a drive system. The bed provides the foundation for the machine and supports the other components. The slide holds the broach and moves it through the workpiece. The drive system is used to power the movement of the slide and the rotation of the broach.

The CNC control system of the machine receives instructions from the operator and controls the movement of the slide and the rotation of the broach. The broach is typically inserted into the workpiece and then moved through it, cutting the internal or external keyway or groove.

CNC broaching machines are used in various industries such as aerospace, automotive, power transmission, and medical device manufacturing, to produce high precision and accurate internal and external keyways, grooves or slots on parts.

CNC broaching machines are known for their high precision, high productivity and ability to cut complex shapes and profiles. They can be used to cut a wide range of materials, including metals, plastics, and composites, and can be used to produce both internal and external keyways and other types of grooves or slots.

Overall, the CNC broaching machine is a specialized machine tool that is used for cutting internal or external keyways, grooves or slots with high precision and efficiency. Its CNC control allows for precise control of the broaching process, and high productivity.
