Chipbreaker NEG Type / NEF Type For Exotic Alloys and Stainless Steel Turning General Features Application Range NEG/NEF type chipbreaker for exotic alloy machining can be used for Titanium alloys, heat-resistant alloys 4,0 NEG NMU and a variety of other exotic alloys. Depth of Cut (mm) NEX They deliver excellent wear resistance and superior chip management. These chipbreakers can solve 2,0 quality problems caused by the unstable tool life and NSU poor chip control provided by conventional chipbrea- NEF kers for exotic alloys. Feed Rate 0 0,2 0,4 (mm/rev) Inserts NEG Chipbreaker for Roughing Provides excellent wear resistance and chip control from general-purpose machining to roughing applications. Reduces damage to insert and eliminates trouble from chips specific to exotic alloys. Also demonstrates very high versatility. Crater wear advancement is prevented by the round Cross Section of Chipbreaker bumps, whilst maintaining excellent control. 1,75 0,09 The cutting edge Excellent chip manage- 30° maintains the strength ment and wear prevention slowing the progress is delivered by the special of crater wear. rake face design. Cutting Performance – NEG Type Heat Resistant Alloy Work Material: Chipbreaker type: NEG (AC510U) Conventional tool (S10) Inconel 718 Insert: CNMG120412 Cutting Data: vc = 40m/min doc = 2,5mm f = 0,2mm/rev Suppresses the chipping of peripheral cutting edge and Wet Notch wear / poor chip control notch wear. Excellent chip management. Tc = 7min Titanium Alloy Work Material: Chipbreaker type: NEG (AC510U) Conventional tool (S10) Ti-6Al-4V Insert: CNMG120412 Cutting Data: vc = 65m/min doc = 2,5mm f = 0,2mm/rev Suppresses crater wear and flank wear. Wet Crater wear / flank wear / poor chip control Excellent chip management. Tc = 8min Application Example – NEG Type Inconel 718, machine component Pure Titanium (Ti grade 3), machine component 3 pcs 3 pcs 3 1,5 times times 2 1 pcs pcs 3x tool life and improved NEG Competitor 1,5x tool life and improved NEG Competitor chip management (AC520U) chip management (EH510) Insert: CNMG120408 NEG (AC520U) Insert: CNMG120408 NEG (EH510) Cutting Data: vc=50m/min, doc=1,5mm, f=0,3mm/rev, Wet Cutting Data: vc=80~100m/min, doc=1,0mm, f=0,25mm/rev, Wet C6
