Positive M Class Chipbreakers for Low Carbon and General Steel Turning FB Type / LB Type P Steel ・ FB type for finishing and LB type for light cutting come in a series of chipbreakers for low carbon and general steel machining in addition to LU type for finishing and SU type for light cutting. ・ The FB and LB type chipbreakers improve chip control in finishing of low carbon and general steel. ■ Application Range 3 Depth of cut (mm) SU type B 2 Inserts 1 LB type FB type C LU type 0 0.1 0.2 0.3 Feed rate (mm/rev) FB Type Chipbreaker for Finishing LB Type Chipbreaker for Light Cutting D R The reinforced edge The ridge reduces the risk of edge breakage. reduces the risk of unexpected breakage S The high rake breaker wall improves chip breaking performance The special breaker ridge shape ensures stable chip control. T The variable rake angle in nose radius increases the 0.5 0.8 chip strain and improves the breaking performance 20° 15° Cross-section of chipbreaker Cross-section of chipbreaker V Performance Performance Chip Control Chip Control W Work material: Pipe steel (STKM13A) φ30 boring Insert: TPMT110304N-FB (T1500A) Work material: Pipe steel (STKM13A) φ30 boring Insert: TPMT110304N-LB (T1500A) Solid CBN Ceramic 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 Stable chip control in shallow Stable chip control cutting at a low feed rate in light cutting 50mm 50mm FB Type (T1500A) Competitor LB Type (T1500A) Competitor Comparison of Surface Roughness of Finished Surfaces Chip Control Work material: Pipe steel (STKM13A) φ100 boring Insert: TPMT110304N-FB (T1500A) Work material: Hub (S45C) Insert: VBMT160408N-LB (T1500A) Cutting conditions: vc=200m/min f=0.07mm/rev ap=0.1mm Wet Cutting conditions: vc=240m/min f=0.25mm/rev ap=0.6mm Wet LB Type (T1500A) 100mm 100μm 100μm Competitor Tool life doubled by improved 100mm FB Type (T1500A) Competitor chip control and reduced surface blemishes B15
