Benefits of Roll Forming
Splines
- Cost per piece savings
- Capital Equipment Savings
- Less Floor Space Required
- No Generating Scallops from Hob
- Good Surface Finish - 3 to 15 R.M.S.
- Increased Strength in Part
- Forms Close to Shoulder
- Chipless Process
- Repeatable Process
- Highly Accurate Process
The Roto-Flo Process
The Roto-Flo forming area consists of an
extremely rigid "C"-shaped machine frame with two
rack-type forming tools mounted on upper and lower hydraulically
actuated slides. The forming tools are designed so that the
tooth height increases successively toward the "finish" end
of the rack. Parts rotate between locating centers as the upper
and lower racks are rapidly traversed in opposite directions,
progressively displacing metal on the periphery of the part/shaft.
To ensure close tolerance control and smooth surface finish,
a number of forming teeth at the finish end of the tools are
full height to allow several revolutions of the part at full-depth
contact.
Spline Design Considerations
- Pressure Angle
