Internal Broaching On CNC Lathe

Internal Broaching

CNC lathes are versatile internal broaching machines that can be used for various tasks, such as internal broaching. Internal broaching is a process that uses a rotating tool to cut into the interior of a workpiece. This process allows you to create precisely sized holes and slots in various materials. To perform internal broaching on a CNC lathe, you must determine the part’s dimensions and select the proper tooling and settings.

What is internal broaching on the CNC lathe?

In broaching, toothed tools are used to remove material from a workpiece. Broaching can be either linear or rotary. Linear broaching is performed on a lathe or milling machine, while rotary broaching is done on a milling machine or drill press.

An internal broach is a type of linear broaching that involves inserting the broach through the tailstock into the hole in the workpiece. The advantages of internal broaching include producing complex shapes, smoother finishes, and rounder holes than other machining processes.

However, internal broaching can be challenging and requires careful tooling design to avoid chatter and vibration.

Advantages of internal broaching on CNC lathe 

Broaching is a machining process that removes material from a workpiece using a toothed tool called a broach. Broaching is often used to produce internal keyways, slots, and splines. Internal broaching can be performed on both CNC lathes and mills, but it is most commonly done on lathes.

One advantage of internal broaching on CNC lathes is that it can be used to produce complex shapes that would be difficult or impossible to produce using other machining methods. Additionally, internal broaching can be used to produce both straight and tapered slots.

This flexibility makes internal broaching an attractive option for many applications. Another advantage of internal broaching is that it generally produces a better surface finish than other machining methods.

This is because the cutting action of a broach leaves a smooth, burr-free surface. Finally, internal broaching is faster and more efficient than other machining internal slots and keyways. For these reasons, internal broaching is often the best choice for many machining applications.

How to do Internal Broaching on CNC Lathe?

On a CNC lathe, internal broaching can be done with the use of a unique tool inserted into the chuck. The tool is then rotated and fed into the workpiece until it reaches the desired depth. The cutting action of the tool removes material from the workpiece, creating a smooth, finished surface.

Internal broaching is an efficient way to create precise internal shapes and can be used to create a variety of different shapes, such as square, rectangular, or even hexagonal holes. In addition, internal broaching can be used to develop keyways, splines, and other features that require tight tolerances. When performed on a CNC lathe, internal broaching can be an accurate and repeatable way to create complex shapes.

Final Thoughts

While the process of internal broaching on a CNC lathe can seem daunting at first, with the right tools and instructions, it can be an easy process. By following the steps in this guide, you should be able to complete an internal broach on your CNC lathe. Have any questions or feedback? Let us know in the comments below!
