Modular Head Series (N) Cutting resistance (N) Cutting resistance Tooling by DIJET EXTREME DIEMASTER MTXTYPE Features ”EXTREME DIEMATE“ EXTDM / MTX type with edge sharpness and strength. ● Achieved edge sharpness and strength by unique helical cutting edge. Adopted radius insert suitable for Double-side usable! turbine blade machining. ● Economical double-side insert (8 corners). Helical cutting edge ● Unique insert rotation preventing structure: Due to wedge-shaped binding face of insert prevents movement of inserts. Able to stable machining. Wedge-shaped ● New PVD coated grade “JC7560P” achieved longer tool life compared with conventional PVD coated grade “JC7560”. ● Insert are arranged in an irregular pitch (except for 3 tooth type). Prevents chattering & vibration. Cutting performance ● Cutting force comparison Material: S50C C50 Cutting conditions: Vc=180/min,　n=1, 146min-1, ae=30mmDow cut – Air blow, Test by 1 insert Cutting force of EXTDM is almost the Overhung length.: 120mm same as the conventional positive cutter.
