Spline Broaching Services for Precision Internal Profiles
At Broaching Technologies, our spline broaching services are performed using rigid vertical slotting machines that provide precise stroke control and repeatable cutting action. This allows us to produce consistent internal spline geometry with reliable tooth form, depth, and surface finish across prototype and production volumes.
What Is Spline Broaching?
Spline broaching is the process of machining multiple internal teeth within a bore to form a spline profile. Internal splines are designed to distribute torque across multiple contact surfaces, improving load capacity and alignment compared to single keyway designs.
- Creates multiple internal teeth within a bore
- Improves torque transmission compared to single keyways
- Maintains accurate alignment between mating components
- Commonly used in hubs, gears, couplings, and drivetrains
Why Spline Broaching Requires Precision Equipment
Spline broaching demands consistent cutting motion and machine rigidity to ensure uniform tooth geometry across the entire spline profile. Variations in depth or spacing can lead to uneven load distribution, increased wear, or premature component failure.
- Precise stroke control ensures consistent tooth depth
- Rigid machine structure minimizes tool deflection
- Controlled cutting motion improves spline 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.
