Depth of Cut (mm) Inserts Chipbreaker Positive M Class Chipbreakersfor Low Carbon and General Steel Turning NFB Type / NLB Type Application Range 3,0 NSU 2,0 1,0 NLB NFB NLU 0 0,1 0,2 0,3 Feed Rate (mm/rev) NFB Chipbreaker for Finishing NLB Chipbreaker for Light Cutting The NFB type for finishing and the NLB type for light cutting have been added to the chipbreaker series for low carbon and general steel machining in addition to the already present NLU type for finishing and NSU type for light cutting. The NFB and NLB type chipbreakers improve chip control in finishing of low carbon and general steel. Ridge reduces edge breakage Strengthened edge reduces unexpected breakage High rake breaker wall impoves chip breaking performance Special breaker ridge shape achieves stable chip control Variable rake angle in nose radius increases chip strain and improves chip breaking per-formance 0,5 0,8 20° 15° Cross Section of Chipbreaker Cross Section of Chipbreaker Performance Performance Chip Control Chip Control  Achieves stable chip control at Achieves stable chip control in small cutting depth and low feed. light cutting. 50mm 50mm NFB Type Chipbreaker (T1500A) Competitor’s Product NLB Type Chipbreaker (T1500A) Competitor’s Product Work Material: Pipe (H240LA), Ø30 Boring Work Material: Pipe (H240LA), Ø30 Boring Insert: TPMT 110304 NFB (T1500A) Insert: TPMT 110304 NLB (T1500A) Cutting Conditions: vc=100m/min, f=0,12mm/rev, ap=0,1mm, Wet Cutting Conditions: vc=200m/min, f=0,15mm/rev, ap=0,5mm, Wet Comparison of Surface Roughness of Finished Surfaces Chip Control  NLB Type Chipbreaker (T1500A) 100mm Competitor’s Product 100µm 100µm Doubles the tool life by improving chip control NFB Type Chipbreaker (T1500A) Competitor’s Product and reducing blemisheson machined surfaces. 100mm Work Material: Pipe (H240LA), Ø100Boring Work Material: Hub (C45) Insert: TPMT 110304 NFB (T1500A) Insert: VBMT 160408 NLB (T1500A) Cutting Conditions: vc=200m/min, f=0,07mm/rev, ap=0,1mm, Wet Cutting Conditions: vc=240m/min, f=0,25~0,28mm/rev, ap=0,6mm, Wet C9
