Modular Head Series WorkToolCutting conditionsResult Tooling by DIJET S-Head SMSRTYPE Solid modular head “Anti-vibration S-Head” SMSR type Features 1. 1Adopted new PVD coated grade “DH115” consisting of the combination of DH COAT & micro- grained carbide. Widely applied from carbon & mold steel to stainless steel & Ti-alloy. 2. Un-equal pitch & irregular helix flutes are excellent in anti-vibration and possible to stable ma- chining. And, achieved good surface roughness in case of machining very thin plate & corners of pockets, by the combination with carbide shank MSN type. 3. Positive rake & coolant hole prevented welding and improved chip ejection. Suitable for machi- ning Ti-alloy & heat-resistant alloy. Un-equal pitch Irregular helix flutes High rigid screw Through coolant hole Irregular helix flutes including corner radius Positive rake Cutting performance Partname Test piece Material Ti-6Al-4V Hardness 36HRC SMSR-4160R10-M8 (ø16-R1)+ Tool No. MSN-M8-70-S16C Insert No. – V-shaped machining Overhung length: 80mm n, (Vc) Vc=100m/min Shoulder milling, Down cut Vf,(f ) f=0.20mm/rev No chatter Chatter ap 16mm ae 0.8mm Coolant Internal coolant Machine Vertical MC Achieved no chatter machining and improved surface roughness compared with conventional tool.
