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.

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.

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.

Frequently Asked Questions

What is spline broaching?

Spline broaching machines multiple internal teeth within a bore to transmit torque and maintain precise component alignment.

How is spline broaching different from keyway broaching?

Spline broaching creates multiple teeth for higher torque capacity, while keyway broaching produces a single internal slot.

Can internal splines be broached accurately?

Yes, internal splines can be broached accurately using rigid machines with precise stroke and tooling control.

What machines are used for spline broaching?

Spline broaching is typically performed on vertical slotting or broaching machines with controlled cutting strokes.

What materials can be spline broached?

Spline broaching can be performed on steels, stainless steel, aluminum alloys, titanium, and high strength alloys.

Is spline broaching suitable for production work?

Yes, spline broaching is well suited for production due to its repeatability and consistent profile accuracy.
