Knurling tools 408

Features of knurl processing

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 • No signficiant change in the outer diameter of the workpiece • Low surface compression • Higher precision and surface quality of the knurl • Lower machine load

2 Cutting Tools

Characteristics

• The outer diameter of the workpiece is increased by material displacement • The surface is compressed • Higher machine load than with knurling

Handling

• Workpiece preparation generally unnecessary • Tool very easy to handle

• Precise tool setting and fine adjustment required • Precise preparation of the workpiece required
