Hardturningreferstotheprocessofturninghardened steelasfinalprocessingorfinishing.Hardenedsteel usuallyreferstoworkpiecematerialsthathavea martensiticstructureafterquenching,highhardness,high strength,andalmostnoplasticity.

Commonpartsforhardturningincludegears,gearshafts, transmissionshafts,windturbinebearings,slewing supportbearings,hubbearings,ballscrews,synch ronizers,ballcageuniversaljoints,three-pinshafts,cross shafts,hardenedmolds,etc.Commonworkingconditions includecontinuouscutting,slightlyinterruptedcuttingand stronglyinterruptedcutting.

Forhardturningofhardenedsteel,Halnnhaslaunched fivematerials:BN-H05,BN-H10,BN-H21,BN-H200and BN-S20.BN-H05materialisusedforcontinuouscutting conditions,BN-H10materialisusedforslightlyinterrupted cuttingconditions,BN-H21materialisusedforstrongly interruptedcuttingconditions,BN-H200isspeciallyusedin thefieldofhardturningofwindpowerbearings,BN-S20is usedforheavy-dutycuttingandlargemargincutting

Forhardturningprocesses,HalnnSuperhardprovides fourinsertstructures,namelystandardCBNinserts,coated CBNinserts,extendededgeCBNinsertsandfully veneeredCBNinserts.

StandardCBNinsertsaremainlycompositeCBNinserts withacuttingedgelengthof2.2mm.
