Height of burr Surface roughness Rz (μm) Flank wear width VB (μm) BN700 Max height of burr (μm) H1 (Carbide) BN700 T110A(Cermet) H1 (Carbide) BN700 T110A(Cermet) H1 (Carbide) T110A(Cermet) Cutting length (km) Cutting speed (m/min) Cutting speed (m/min) Work material: SMF4040 equivalent For general power metal components, carbide and cermet grades can perform up to Vc=100m/min. However, around Process details: ø100~300mm heavy interrupted facing with grooves and drilled Vc=120m/min, wear becomes rapid and surface roughness deteriorates with increased burrs. holes. (after 40 passes) SUMIBORON on the other hand, exhibits stability and superior wear resistance, burr prevention and surface roughness Insert: TNGA160404 Cutting data: f=0.1mm/rev, d=0.1mm, Wet especially at high speeds.
