Halnn CBN inserts solutions for hard turning Gear steel
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 tools has successively developed BN-H10
and BN-H21 CBN 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 .
CBN inserts for continuous turning gear--BN-H10 CBN inserts
When continuously cutting high-hardness workpieces, CBN inserts need to
have high wear resistance, longer tool life, and high surface finish of processed
workpieces. Halnn CBN inserts BN-H10 can not only meet the above
requirements. And the production cost per piece is greatly reduced compared
with imported CBN inserts.

CBN inserts for intermittent turning gear--BN-H21 CBN inserts
Intermittent turning conditions, CBN inserts 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
inserts 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.
