Knurling is an operation which deforms the material, using toothed knurling wheelsknurling wheelA hardened corrugated steel roller when forced against a rotating workpiece the rollers produce a parellel or inclined pattern.

Detail on a cylindrical surface to improve adherence. This operation requires a pressure of several tonnes, applied hydraulically.
During subsequent fabrication processes, the knurled part offers resistance and adherence during molding operations (such as plastic) or countersinking of end pieces, gears, magnets or any other component.
Depending on the profile of the knurling wheels used, the grooves produced on the knurled part may be straight, helicoidalhelical or helicoidal or spiral (helicoidally)Having the form of a helix, the helix being a curve formed by winding a straight line around a cylinder.Examples : the left-hand...
Detail or crossed.
As for polygonal turning, the knurling process is carried out directly on the screw machine at the same time as the turning operations.
