Indexable Tools Cutting resistance (N) Cutting resistance (N) Tooling by DIJET TDM EXTREME EXTDMTYPE Feature of product "EXTREME DIEMATE" EXTDM / MTX type with edge sharpness and strength. ● Achieved edge sharpness and strength by unique helical cutting edge. Adopted radius insert suitable Double-side usable! for 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 ● Insert are arranged in an irregular pitch (except for 3 tooth type). Prevents chattering & vibration. Cutting performance Cutting force of EXTDM is almost the sameas the conventional positive cutter. ● Cutting Material: S50C force C50 comparison ● Cutting Material: S50C force C50 comparison Cutting conditions: Vc=120/min, fz=1.0mm/t, ap=0,6mm, ae=15mm Cutting conditions: Vc=120/min, fz=1.0mm/t, ap=0,6mm, ae=15mm Down cut, Air blow, Tbool No.: EXTDM-5050R-12-22 (ø50), Dow cut, Air blow, Tobol No.: EXTDM-5050R-12-22 (ø50), Insert No.: RNMU1205MOE-MM (JC7560P) Insert No.: RNMU1205MOE-MM (JC7560P) 1,400 ap=1mm, fz=0.4mm/t 4,500 ap=3mm, fz=0.6mm/t 1,200 4,000 3,500 1,000 3,000 800 X (Feed force) 2,500 X (Feed force) 600 2,000 Y (Main force) Y (Main force) 1,500 400 Z (Back force) 1,000 Z (Back force) 200 500 0 (Resultant force) 0 (Resultant force) Conventional tool EXTDM type (ø50, negative) Conventional tool EXTDM type (ø50, negative) C128
