Chipbreaker NFE Type / NFB Type (A t CD (A Zc7 Z7 D ZK7 Negative M Class Chipbreakers for Low Carbon and General Steel Turning General Features The high performance NFE type, which ensures stable chip control in a wide range of feed rate, has been added to the chipbreaker series for low carbon steel and general steel turning. Extensive product lines are available to meet various machining requirements. A positive insert execution of chipbreaker NFB is also available. Application Range 0,2 0,3 0,4 Feed Rate (mm/rev) NFE Chipbreaker for Finishing Supports general purpose machining to high speed machining. Performance The arc-shaped main breaker ensures stable chip control in a wide feed rate range. The two step chipbreakers enable stable chip control at a low feed rate of f = 0,1mm/rev. The sub-breaker controls cutting chips in profiling. Application Examples Work Material: Pipe steel (H240LA, 1.0480) Insert: CNMG 120408 NFE (AC8025P) Cutting Conditions: vc=200m/min, f=0,4mm/rev, ap=0,2mm, Dry Excellent chip control under low depth of cut and high feed rate condition NFE Type (AC8025P) Conventional Work Material: Deep-draw steel (SPHC440) Facing Insert: CNMG 120408 NFE (AC8025P) Cutting Conditions: vc=200m/min, f=0,15mm/rev, ap=0,2-0,5mm, Wet Stable chip curling and breaking in facing of gummy steel. iv\v Work Material: C53E,1.1210, 020-100 Exter. Turning+Facing Ins.: DNMG 150412 NFE (AC8025P) Cutting Conditions: vc=180m/min, f=0,25mm/rev (radius), 0,45mm/rev (straight section), ap=0,3mm, Wet Stable chip control even at a variable feed rate in shallow cutting. S NFE Type (AC8025P) Supports low feed machining.
