The application of Halnn cbn insert in hard turning industry
With the upgrade of machinery industry, more and more high hardness materials appear and are used in machinery industry. For this situation, Halnn researched new cutting tools materials to help the manufacturer to solve their problems. We mainly reserach brittle hard materials--diamond tools and cbn inserts, and already enjoy high reputation. Our cbn inserts have been used so many manufacturers from all over the world.
Hard turning also called “Turning instead of Grinding”, with the increasing requirements on the mordern component, it will require high on the cutting tools performance, such as the tolerance, roughness and special machining condition interrupt. For this situation, we researched BN-H10 and BN-H21 cbn grades, which are used for continuous turning and interrupt turning and perform well in hard turning industry. If some customers also would like to improve the precision, Halnn also can offer coating cbn or wiper cbn. We will make the whole solutions depending on the customers’ requirements.
BN-H10---Continuous PCBN insert grade
When turning high hardness workpiece with continuou, cbn insert need high abrasive resistance and good roughness, the can obtain long tool life. Halnn BN-H21 can meet all the requirements, and the cost on each component will reduce much.
One of the application case as follows:
|
BN-H10 PCBN hard turning gears |
 |
Machining condition:Continuous
Hardness: HRC58~62
Insert Model: BN-H10 CNGA120408
Cutting Speeds and Feeds: Vc=180m/min,Fr=0.1mm/r,ap=0.2mm |

BN-H21-interrupt turning condition cbn insert grade
When meet interrupt turning condition, the cbn insert not only need high abrasive resistance, but also need good impact toughness. Halnn BN-H21 use nano blinder and high pure cbn grain, which will meet the requirements of stable performance on interrupt turning condition for gears, gears shaft.
One of the application as follow:
|
BN-H21 PCBN Insert hard turning gears |
 |
Machining condition:Interrupt Cut
Hardness: HRC58~62
Insert Model: BN-H21 WNGA080408
Cutting Speeds and Feeds: Vc=300m/min,Fr=0.1mm/r,ap=0.3mm |
