Knurling Technology – Form Knurling Tools / Cut-Knurling Tools

Wide range of knurling tools and knurling wheels, both for cut-knurling and form-knurling, for a perfect knurling operation on all types of lathes.

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 (plongОe) is used.
  2. When the profile to the machine is RGV, RKE, 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.

Cut-knurling

In cut-knurling the teeth are generated by removing material. This type of knurling does not generate overstrain on the machine, and in many cases a higher quality and more accurate knurling is obtained.

The tools used for this knurling technique fit knurls with a 30˚ angle in relation to the rotation axis of the piece. Due to this inclination, the knurls cut the teeth while they are turning along the piece.

The cut-knurling system does not generate an increase in the diameter of the machined piece, as in theory the material is not deformed. Although it must be stated that there is always a slight displacement of the material that even though it is not of the same magnitude as that generated by form knurling, it must be taken into account when the piece to be made requires a certain precision in the final diameter.

This knurling system is not applicable in all cases. Only RAA, RBL, RBR and RGE profiles can be run with cut-knurling tools.

  1. Cut-knurling makes it possible to execute thin walled tubular pieces, whereas with form knurling it is impossible.
  2. When the material to be knurled is not deformable as plastics, nylon, cast iron.
