BNC2115 / BNC2125 / BNC2010 / BNC2020 / BNC300 Coated CBN for Hardened Steel Machining BNC2115 / BNC2125 / BNC2010 / BNC2020 / BNC300

█ Application Examples of BNC2115/BNC2125 Hardened Steel Gear (4130H) (60HRC)

Hardened Steel Ring Gear (5140H) (60HRC) BNC2115 with a WH type wiper insert maintains excellent surface roughness longer than the competitors' coated CBN (wiper insert)

Compared to competitors' coated CBN, BNC2115 reduces flank wear width by 30%, able to continue with good surface roughness
