Hard turning hardened steel after heat treating used CBN insert Grade

Part 1 The problems of CBN insert hard turning hardened steel

1.Hardened steel problems: High hardness; interrupted turning process; Large deformation;

2.Cutting Tools difficulties: Carbide insert has low hardness; Ceramic insert has large brittleness; Traditional cbn insert will be easily chipping.

Part 2 The solutions of Halnn CBN insert hard turning hardened steel after heat treating

Specific to the current problems on hard turning hardened steel after heat treating, Halnn researched special cbn insert ,and offer the effective solutions as follows:

CBN insert grade	Machining Process	Advantages	Application industry	Insert Picture
BN-H10	Finishing	Suit for finishing with high speed, balance the wear resistance and Collapse resistance	Bearing , gear, gear shaft, constant speed coupling, pearlite ductile cast iron
BN-H21	Finishing	The tips has excellent strength and performance well in interrupted turning conditions	Gear and gear shaft ,mold steel
BN-H11	Finishing	It has more flexible with the cbn insert clamping way, higher machining accuracy, more than one tip	Bearing, Gear, Gear shaft, Constant speed coupling, hardened abrasive
BN-H20	Finishing	it has a good wear resistance and crack resistance when hard turning hardened steel	Brake disc, brake drum, cast iron parts, chilled steel gear
BN-S20	Finishing & Roughing	It has a good chipping resistance and fracture-resistant in a high temperature	Hardened steel rolls, ball screw, wind power bearing ,high speed steel rolls
BN-S200	Finishing & Semi-finishing	It has a better wear resistance when hard turning hardened steel and heat resistance alloy	Slewing bearing, forged chilled rolls ,sintered tungsten carbide
