Competitor's Cutter A 129cc/min Competitor's Cutter B 84cc/min [Competitor's Cutter A] Because conditions can be raised drastically, very effective for [Competitor's Cutter B] MSRS15 can complete machining with 1 pass for what needed φ125, 6 inserts time crunch. Machining with 2mm × 3 passes to be cut with 3 passes usually. Still machining sound of Vc=150m/min (n=382min-1) Productivity improved by 4.4 times. Vc=150m/min (n=300min-1) MSRS was quiet.

A-1 The estimated amount is 70 to 80% of diameter of the cutting tool. Milling Q-2 Why does the MSRS15 type have a cutting angle 75°? A-2 45° cutting angle type can reduce an impact in biting a workpiece but increase a thrust force. On the other hand, Inserts 90° cutting angle type can reduce a thrust force but increase an impact in biting a workpiece. Lead Angle 75° cutting angle MSRS15 type can suppress both a thrust force and impact in biting keeping a good balance 45°/20° and enable smooth machining even in large machining.
