If you are involved in any of the industries that are related to industrial production or manufacturing processes, then probably you will know what broaching is, but many people still do not understand exactly how and why broaching is used.
Broaching has been one of the most precise means of machining for more than 100 years, and it continues to be a significant contributor to the manufacture of high-quality and critical parts throughout the manufacturing sector. Here at Suntech Landriani Machine Tools Pvt Ltd, we have been at the forefront of developing broaching technology to produce precision, reliability, and quality for our global customer base.
This blog post provides an overview of broaching including a straightforward explanation of what broaching is, how broaching works, and which industries benefit most from utilizing this process.
What Is Broaching?
Broaching is a machining process that uses a toothed tool called a broach to remove material and create a specific shape in a single smooth motion.
Think of it as pulling or pushing a very precise tool through metal to create features like:
- Keyways
- Splines
- Holes
- Internal and external profiles
- Slots
- Serrations
- Gear shapes
A broach has a series of progressively larger cutting teeth arranged in a straight line. As the tool moves across the material, each tooth removes a small amount of metal, resulting in a perfectly accurate and clean shape.
Why Is Broaching Important?
Broaching stands out because it delivers:
✔ High Precision
It can achieve extremely tight tolerances, often impossible through manual methods.
✔ Speed & Efficiency
Once the tool is set, broaching produces the final shape in one single stroke.
✔ Consistency
Ideal for large-scale production where every component must be identical.
✔ Excellent Surface Finish
Broaching leaves behind a smooth, refined surface requiring minimal finishing.
These advantages make broaching one of the most dependable methods for producing complex shapes quickly and accurately.
Types of Broaching
Broaching can be done in different ways depending on the requirement:
- Internal Broaching: Creates shapes inside holes like keyways or splines.
- External Broaching: Used on the outer surface of components like flat surfaces or splines.
- Vertical & Horizontal Broaching Machines: Depending on the size, direction, and application.
- Surface Broaching: Used for external profiles and surfaces.
- Rotary Broaching: Often used for precision shapes in high-speed production.
Where Is Broaching Used? (Who Needs This Process?)
Broaching is essential across many industries, especially those requiring high accuracy, complex profiles, and consistency in parts:
1. Automotive
- Transmission parts
- Gears
- Shafts
- Steering components
- Keyways
2. Aerospace
- Turbine components
- Structural parts
- High-strength metal shaping
3. Defence
- Weapon components
- Precision fittings
4. Industrial Machinery
- Gear cutting tools
- Heavy equipment parts
- Customized metal profiles
- Transmission parts
5. Oil & Gas
- Drilling components
- High-durability parts
6. Tool & Die Manufacturing
- Precision tools and cutters
7. Electrical & Power Transmission
- Motor components
