Cutting Tools
Form knurling
Knurling process
Application
• Processing cold-formable materials
• Knurling on thin-walled workpieces is problematic
• Wider application scope
• All knurled forms and profiles can be produced
• Suitable for face and inner knurling
• Knurling up to the collar possible
• Tool can be applied to any part of the workpiece
• Processing of almost all materials possible
• Thin-walled workpieces can be processed
• Suitable for visible knurls – highest knurl quality
• Restricted application areas
• Only RAA and RGE knurl profiles are
achievable
• Cylindrical workpieces can only be
processed in the axial direction of machining
• To prepare the tool in the central area of the
workpiece a punch is required
Characteristics
• The outer diameter of the workpiece is increased
by material displacement
• The surface is compressed
• Higher machine load than with knurling
• No signficiant change in the outer diameter of the
workpiece
• Low surface compression
• Higher precision and surface quality of the knurl
• Lower machine load
Handling
• Workpiece preparation generally
unnecessary
• Tool very easy to handle
• Precise tool setting and fine adjustment required
• Precise preparation of the workpiece required
