PROPERTIES OF THE KNURLING METHODS Use Machining cold workable materials Forming knurls on thin-walled workpieces is problematic Wide range of uses All knurl forms and profiles can be made Suitable for face and internal knurling Knurling possible up to collar Tool can be position on any point on the workpiece Properties The external diameter of the workpiece is increased by material displacement The surface is compressed Higher machine load than for knurl milling Handling In general the workpiece does not require preparation Very easy tool handling 1 Knurl forming Groove knurling Longitudinal knurling Groove and longitudinal knurling Radial tangential machining direction Axial machining direction Radial and axial machining direction NORGAU 197 Cutting tools
