Keyway Broach Set
Description
A Keyway Broach Set is a collection of precision cutting tools used to cut keyways (slots) inside holes such as gears, pulleys, and hubs. It is commonly used with a press to produce accurate and uniform keyways.
Uses
- Cutting internal keyways in hubs and shafts
- Used in gears, pulleys, and machine components
- Ensuring proper fitting of keys
- Maintenance and manufacturing applications
Parts
- Broach (cutting tool)
- Guide bush
- Shims (for depth adjustment)
- Storage case
Material
- High-speed steel (HSS)
- Alloy steel (in some types)
Working Principle
The Keyway Broach Set works on the principle of progressive cutting. The broach is pushed through the workpiece using a press. Each tooth on the broach removes a small amount of material, gradually forming a precise keyway slot.
Advantages
- Produces accurate and uniform keyways
- Simple and effective operation
- Suitable for batch production
- Provides good surface finish
Safety Precautions
- Ensure proper alignment before broaching
- Use correct size broach and bush
- Apply proper lubrication
- Do not apply excessive force
- Wear safety gloves and goggles
Conclusion
The Keyway Broach Set is an essential tool for producing accurate keyways in mechanical components. Its precision and efficiency make it widely used in manufacturing and maintenance work.
