(after 40 passes) Insert: TNGA160404 Cutting data: f=0.1mm/reV, d=0.1mm, Wet 100 150 Cutting speed (m/min) For general power metal components, carbide and cermet grades can perform up to Vc=100m/min. HoweVer, around Vc=f20m/min, wear becomes rapid and surface roughness deteriorates with increased burrs. SUMIBORON on the other hand, exhibits stability and superior wear resistance, burr preVention and surface roughness especially at high speeds.
