Keyway Broaching Services for Precision Internal Slots
At Broaching Technologies, our keyway broaching services are performed using rigid vertical slotting machines that provide precise stroke control and consistent cutting action. This approach allows us to produce accurate internal keyways with reliable depth, width, and surface finish across both prototype and production volumes.
What Is Keyway Broaching?
Keyway broaching is the process of machining a single internal slot within a bore to accept a mating key. This slot allows torque to be transferred from a shaft to a hub while maintaining proper alignment between components.
- Machines a single internal slot within a bore
- Allows torque transfer between shaft and hub
- Maintains alignment between mating components
- Commonly used in gears, pulleys, hubs, and couplings
Why Keyway Broaching Requires Precision Equipment
Keyway broaching requires accurate control of slot width, depth, and straightness to ensure proper fit and load transfer. Variations in geometry can lead to poor alignment, uneven load distribution, or premature wear.
- Precise stroke control ensures consistent keyway depth
- Rigid machine structure minimizes tool deflection
- Controlled cutting motion improves slot accuracy
- Repeatable results across production volumes
As the exclusive US distributor of CAMS slotting machines, Broaching Technologies operates the same precision equipment we supply to manufacturers, giving us unmatched insight into what these machines can achieve in real production environments.
