Gear Industry Solutions
There are many difficulties on hard turning Gear after heat treating:
(1)The hardness of the Gear will reach HRC58~62, the insert will wear
rapidly, which will affect the processing efficiency.
(2) Some Gears exist interrupted turning condition(end surface has
hole), the cutting tools will be easily chipping, so the costs will be high.
(3) For large scale Gears, the hardness after heat treating will be high,
and the deformation also will be large, it will require high wear
resistance and impact resistance on the cutting tools.
Specific to above difficult problems, Halnn researched solid cbn inserts
BN-S20 for roughing with large margine and pcbn inserts BN-H11, BN-
H21, BN-H20,BN-H10 for finishing, which will make sure the excellent
wear resistance, strong impact resistance and anti-fracture properties.

Bearing Industry Solutions
When processing large scale bearings and fine finishing bearings,
the manufacturers usually use hard turning instead of grinding which
is a trend in bearing industry, and it has high performance, low
costs, traditional technology can’t go beyond that.
As the leader of professional superhard cutting tools, Halnn
researched professional cutting tools grades for hard turning
bearings, which not only has stable cutting performance, but also
promises high roughness, and help the manufacturers to reduce the
production costs.
