CBN Tooling Solution for Stable Wind Turbine Bearing Raceway and Face Machining

A Process-Based CBN Tooling Strategy

Hard turning of HRC58–64 bearing steel concentrates heat at the cutting edge and may introduce intermittent impact, especially around raceway transitions and grooves. A single insert geometry rarely balances stock removal, finish retention and groove stability. UHD addresses this by matching CBN grade, cutting-edge strength and insert geometry to each operation.

Integral Brazed CBN Insert Series — Roughing

Used for bearing ring and face roughing, including rough raceway machining. Its configuration emphasizes cutting-edge strength and resistance to impact for stable stock removal under HRC58–64 conditions.

Coated CBN Insert — Raceway Finishing

Applied to high-speed hard finishing of inner and outer ring raceways. The focus is wear resistance and thermal stability to help limit accuracy drift caused by uneven insert wear.

Solid CBN Insert Series — High-Precision Finishing

A finishing option for high-end wind turbine bearing raceways with tighter tolerance requirements. It is intended for processes requiring enhanced repeatability alongside controlled machining parameters.

CBN Grooving Insert Series — Seal and Oil Grooves

Dedicated for seal grooves and lubrication oil grooves, where interrupted cutting can cause chipping, burrs and dimensional variation. Geometry can be matched to groove structure and cutting impact.
