Flank Wear (μinch) Wear Resistance CBN & PCD TURNING INSERTS MB4120 aThe first recommendation that can be widely used for continuous to interrupted cutting of sintered alloy and cast iron. FEATURES High Fracture Resistance B Fine CBN particles increase cutting edge toughness. The high fracture resistance allows stable performance even during interrupted machining. High Adhesion Strength MB4020 MB4120 of Fine CBN Particles MB730 Optimization of the sintering conditions strengthens adhesion between fine CBN particles. This increases both fracture resistance and wear resistance. Fracture Resistance y Application Example Fracture Resistance Comparison During Interrupted Facing of High Strength Sintered Alloy MB4120 Conventional A Work Material: High Strength Sintered Alloy Insert : NP-TNGA332-SE3 Cutting Speed : vc= 490 SFM Feed : f=.006 IPR Conventional B Depth of Cut : ap=.004 inch Cutting Mode : Wet Cutting 0 50 100 150 200 Excellent chipping resistance in interrupted face No. of Passes Before Fracture cutting of gear.
