Chipbreaker Series for Stainless Steel Turning EF / EG / EM Type Stainless Steel · The chipbreaker series for stainless steel machining features EF type for finishing, EG type for medium cutting and EM type for roughing. · The EM type achieves both excellent wear resistance and high cutting edge strength. · The EG and EF type breakers are ideal for a variety of exotic alloys Insert including titanium alloy and heat-resistant alloys. · Achieves both excellent wear resistance and strong chip control, reducing issues with equipment and quality that occur in conventional chipbreakers due to unstable tool life and chips. ■ Application Range B Stainless steel machining Milling of Exotic Alloys 6.0 EG Type EG Type EM Type Neg. 4 EM Type Depth of Cut ap (mm) EX Type Depth of Cut ap (mm) EX Type MU Type UP Type MU Type 4.0 GU Type EF Type 2 SU Type SU Type EF Type Pos. 2.0 0 0.2 0.4 0.6 0 0.2 0.4 Feed Rate f (mm/rev) Feed Rate f (mm/rev) C EF Type Chipbreaker for Finishing EM Type Chipbreaker for Roughing ● Reduces curl diameter of chips during finishing, ● Achieves excellent fracture and crater wear resistance and achieving outstanding chip control enables extremely stable machining. D A main breaker that provides Breaker shape that reduces good chip control even with low crater wear and provides good depth of cut fracture resistance R S Sharpness was prioritized Grooved rake face to in the rake angle (20°) to reduce heat and shock at reduce wear deflected angles T Performance EG Type Chipbreaker for Medium Cutting ● Achieves excellent wear resistance and strong chip control in V general purpose to medium cutting. Highly versatile performance Spherical projections on rake face Work Material: Stainless Cast Steel (Equivalent to maintain chip control performance SUS316) Flange part W when crater wear occurs Insert: SNMG190616 (AC6030M) Cutting Conditions: vc=70m/min ø700 f=0.5mm/rev, ap=0.3 to 8.0mm, wet Solid CBN Ceramics Round cutting edge Special rake face limits crater wear maintains strength even after wear occurs and achieves strong chip control EM Type Chipbreaker Conventional Tool (AC6030M) Reduces cutting edge breakage and enables stable machining B19
