Spline Shaping Principles

The spline cold forming is actually a shaping process without stock removal, in which root materials are gradually extruded and replaced up to the crest.

 

Through our computation procedure, you can easily figure out the theoretical diameter of materials necessary for shaping and you can get the final diameter after adjustment.

Advantages of cold forming: (compared with old cutting processing)

1) efficiency is increased up to more than 30 times.

2) work piece bearing capacity is increased to 40%.

3)roughness can reach below Ra0.4.

4)materials saved to 9%-15%.

5)fatigue strength, torsion strength, and wear resistance are sharply improved.
