Knurling Tools

Knurling Tools - workpiece_top

Knurling has a wide variety of applications in day-to-day use. It is most commonly used for decorative purposes and for serration surfaces where components are locked or keyed together in unit assemblies.

Knurling is obtained by displacement of the material when the knurl is pressed against the surface of a rotating work blank. A knurled tooth is “V” shaped.
Knurling tools are used for producing straight, diagonal  or diamond patterns, having teeth of uniform pitch on cylindrical surfaces.

 

KNURLING APPLICATIONS

Knurling_applications


FORMING

end feed

Knurl forming is achieved by pushing the knurl wheels against the blank while rotating.
This will cause the material to be displaced in cold form, reproducing the same wheel pattern on the blank circumference.
The blank is increased accordingly to the Knurl Pitch. The force applied through forming is increased in larger diameters
making knurling difficult and slow.

CUTTING

in-feed

Knurl cutting is achieved by using knurl wheels to actually cut instead of forming the blank.
The knurl wheels are set at an angle, making the knurling edges of the knurl wheels cut into the blank.
Pressure is minimized while speed and feed are increased.

3 WHEEL KNURLING VIDEO

Dorian Tool 3-Wheel Knurling Tool is designed to knurl small diameter and excessively long parts where push-type knurling tools will deflect the material. The 3-Wheel knurling tool will knurl the parts with tight tolerances and superior knurl quality because the three wheel knurling system applies less pressure per wheel, controlling the displacement and  the form of the material.

CNC 100 MODULAR VIDEO

Dorian Tool Modular Knurling Tools provide a solution for any challenging knurling application. The modular cut-type knurling tools have revolutionized knurling by allowing faster speeds and feeds, and lower tool pressure than form-type knurling.
