Chipbreaker Series for Stainless Steel Turning M EF Type / EG Type / EM Type Stainless steel ・ EF type for finishing, EG type for medium cutting and EM type for roughing are available as a series of chipbreakers. ・ The EM type achieves excellent wear resistance and cutting edge strength. ・ The EG type and EF type are suitable for machining a various kinds of exotic alloys including titanium alloy and heat resistant alloy. ・ Excellent wear resistance and chip control improve the equipment and quality problems caused by the unstable tool life and poor chip control of the conventional B chipbreakers. ■ Application Range Inserts Machining stainless steel Machining exotic alloy 6.0 EG type EG type C EX type EM type 4 Depth of cut (mm) UP type MU type Depth of cut (mm) EX type 4.0 GU type MU type EFtype 2 SU type SU type EF type D 2.0 0 0.2 0.4 0.6 0 0.2 0.4 R Feed rate (mm/rev) Feed rate (mm/rev) EF Type Chipbreaker for Finishing EM Type Chipbreaker for Rough Cutting S ● Reduces the chip curl diameter in finishing applications for ● Provides excellent fracture resistance and crater wear excellent chip control resistance for stable machining Main chipbreaker achieves excellent The breaker shape ensures reduced crater T chip control even in shallow cutting wear and excellent fracture resistance V W The sharper edge with rake angle of The rake face groove shape reduces heat and 20 degrees reduces wear prevents uneven contact with the workpiece Solid CBN Performance Ceramic EG Type Chipbreaker for General Purpose ● Provides excellent wear resistance and chip control in the application range from general purpose to rough cutting. Round bumps maintain chip control Work material: Stainless cast steel after crater wear has occurred (equivalent to SUS316) flange component Insert: SNMG190616 (AC6030M) Cutting conditions: vc=70m/min ø700 f=0.5mm/rev ap=0.3 to 8.0 mm Wet The edge shape is designed to maintain The special rake face profile reduces crater the strength after wear has progressed wear and achieves excellent chip control EM Type Conventional (AC6030M) Reduced risk of edge breakage and stable machining B17
