PCBN BN-H21 CBN Cutters Inserts Interrupt Cutting Hard Part Turning Hardened Steel Gears

1. Advantage.

With the transformation and upgrading of the manufacturing industry, more and more high-hardness and difficult-to-machine materials are used in the manufacturing industry, and in the face of continuous updating of mechanical metal parts and materials,Halnn Superhard has successively developed BN-H10 and BN-H21CBN inserts for continuous cutting and interrupted cutting conditions, and has outstanding advantages in the field of hard turning, and provides coatings and wipers CBN inserts.

2. Advantages of turning gears compared to grinding processes.

Cost: The investment of lathe is only 1/3-1/10 of the grinding machine, which not only reduces the capital investment of machine tools, but also enables flexible production and efficient use of equipment;

Quality: 80% of the heat generated during the turning of the gears is carried away with the chips, avoiding problems such as burns and cracks during the grinding process;

Efficiency: Turning efficiency is 4-6 times of grinding;

Environmental aspects: Turning gears are mostly dry-cutting, which enables clean production and ensures a good working environment, while the chips are easier to recycle.

3. Case of CBN tool hard turning gear.

Continuous cutting conditions: 

Halnn CBN tools BN-H21 and BN-H11 materials are recommended for 

high-speed cutting, Compared to ceramic tools, the tool life is up 
to N times, while coated CBN inserts are available.
