Solution for hard turning hardened steel gears of CBN
tools
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 tools for continuous cutting and interrupted cutting
conditions, and has outstanding advantages in the field of hard turning, and
provides coatings and wipers CBN tools .
CBN tool for continuous turning gear--BN-H10 CBN tools
When continuously cutting high-hardness workpieces, CBN tools need to have
high wear resistance, high tool life, and high surface finish of processed
workpieces. Halnn CBN tools BN-H10 can not only meet the above
requirements. And the production cost per piece is greatly reduced compared
with imported CBN tools.

CBN tool for intermittent turning gear--BN-H21 CBN tools
Intermittent turning conditions, CBN tools not only need to have high wear
resistance, but also need to have strong impact toughness and fracture
resistance, and encounter oil holes or keyways without chipping. Halnn CBN
tools BN-H21 uses nano-scale binder and high-purity CBN particles to optimize
the ratio, which can meet the stable interrupted cutting of gears, gear shafts
and bearings.
