1 TOOLING NEWS E-118 P M K N S H Super FF Coated Inserts for Steel Turning / / / High Speed Turning >3m/min High Speed Turning General Purpose Turning Interrupted Turning Excellent solution for machining of steel High-speed and efficient cutting Increased wear and breakage resistance First choice for long tool life and high feed rates Perfect combination of chipbreaker and grade

2 /// Features AC8P Series covers a wide range of machining applications from high speed to interrupted cutting. All grades feature Super FF Coat, which has excellent wear and chipping resistance. Versatile NGE Type chipbreaker suited to high-feed applications. High efficiency, long tool life. : The ultra-thick Al 2 O 3 coating achieves excellent wear resistance at high speed cutting above 3 m/min under dry cutting conditions. : In addition to FF-TiCN coat, this grade features a tough, thick Al 2 O 3 coating enhanced by newly developed grain growth control technology, excellent wear resistance and long tool life in high-speed, high-feed cutting. : In addition to FF-TiCN coat, this grade features a high-density structured FF-Al 2 O 3 layer using new smooth surface treatment technology, and also employs coating thickness control technology to achieve excellent versatility, stability and long tool life. : In addition to FF-TiCN coat, this grade features a strengthened FF-Al 2 O 3 layer using new stress control technology and moreover provides excellent reliability and wear-resistance in heavy interrupted cutting to achieve long tool life. Application Range Coating Structure 1,5 times thicker Al 2O 3 coating Cutting Speed (m/min) Continuous Interrupted Heavy Interrupted Achieves excellent crater wear resistance under high speed cutting (v c > 3m/min). Cutting Conditions Cutting Performance 11,5 min 11 min Flank Wear Vb (mm) A B A B 11,5 min 1 min Cutting Time (min) Work Material: Cutting Data: C55 (1.535) CNMG12412 v c=3m/min, f=,5mm/rev, a p=2,mm, wet Grade shows excellent crater wear resistance. 2

3 High Feed Chipbreakers NSE / NGE / Chipbreakers Features The ability to control chip size and chip direction is vital for efficient production, unmanned machining and protection of the tool / workpiece. The unique design of three new chipbreakers NSE for finishing applications, NGE for general purpose turning and for roughing enables smooth chip flow across a wide range of feed rates even at elevated cutting speeds and increased depths of cut. NSE NGE Primary ridge Primary ridge Wide and shallow breaker geometry Side ridge Wave shaped cutting edge Side ridge Smooth curve rake face Smooth curve rake face Dimple surface Chip Control Rake face profile relieves stress concentration with smooth chip evacuation. Conventional chip flow New chip control by NSE / NGE / Limited chip contact area increases stress and causes insert damage. Smooth flow improves chip direction and shape.
