Form knurling

In form knurling, the teeth are generated by deformation of the material because the knurls exert pressure on the piece while it turns. This method is made without removing material, so no chips are produced. Due to the deformation of the material, the diameter of the piece is increased. The value of this increase is variable, as it depends on the material of the piece machined and the form and pitch of the teeth generated (see table page 8).

1. Form knurling is imperative when a radial knurling technique (plongée) is used.
2. When the profile of the machine is RGV, RKE, or RKV.
3. When the final diameter of the piece needs to be bigger than the starting diameter.
4. When you have to make a knurling in the bottom of a throat.
5. To make knurling till a face.
6. To knurling in cones or front faces.
