Blade Arrangement in Spline Broaches
For internal spline broaching, the placement of the round (minor diameter) teeth relative to the spline-cutting teeth is a critical design decision that affects concentricity, tolerance control, and overall accuracy.
In a front round blade arrangement, the round teeth come first. They true up the bore diameter before spline cutting begins, which is advantageous when the pre-broaching hole has a wide dimensional tolerance.
A rear round blade configuration places the round teeth after the spline teeth. This is the more common general-purpose arrangement and works well when the primary concern is controlling the minor diameter tolerance of the finished spline.
Combination (alternating) arrangements interleave round and spline teeth in the finishing section. The spline teeth act as guides while the round teeth are cutting, which significantly reduces eccentricity between the spline form and the minor diameter.
Some designs combine all of these strategies—front round teeth for initial bore sizing, followed by alternating spline and round teeth in the finishing section—to achieve the highest possible concentricity.
