Solid Carbide End Mills Tooling by DIJET “One-Cut Radius”End Mill for Heat Resistant Alloy DV-OCSARTYPE Features of DV-OCSAR type Adopted un-equal pitch and irregular helix Un-equal pitch flutes including corner radius solved vibration problems (possible to stable machining for very β α thin plate) α≠β Adopted positive rake reduced cutting heat α β top revent welding. Irregular helix flutes The combination of 42° & 45° helix angle improve reliability and surface roughness θ1°≠θ2° Newly developed VALUECOATING has excellent heat resistance and wear resistance Adopted un-equal pitch & irregular helix flutes including corner radius solved vibration problem. ■ CUTTING PERFORMANCE (1) INCO718 DIJETDV-OCSAR4120-30 Competitor I Longer Competitor B tool Competitor A life 0.35 Competitor I :2.7m 0.3 0.25 Competitor A :7.2m 0.2 Competitor B :3.6m ae~0.6mm 0.15 0.1 Material: INCO718 (Age hardened) Tooldia: φ12mm DIJET: DV-OCSAR Vc=50m/min,f=0.20mm/rev, 0.05 8.1m ap=18mm,ae=0.6mm No chipping!
