Slewing ring

The slewing ring connects the tower to the nacelle, making it rotate to utilize the direction and speed of the wind. Three smaller slewing rings connect the turbine blades with the hub to adjust the pitch angle of the blades for maximum yield.

1. Turning – Roughing
The T-MAX® P concept geometries are carefully designed for perfect chip breaking. Metal removal at high feed and in dry conditions is made possible with state-of-the-art grades for your application.

2. Turning – Finishing
Try the WM Wiper productivity booster for the finishing operation, where tolerances and surface finish are crucial.

3. Drilling
By simply replacing a conventional drill with a CoroDrill® 880, you can double the number of drilled holes in the same amount of time.
Its step technology offers outstanding cutting force balance, providing significant improvements in productivity as well as hole quality. This, in combination with high performance grades, makes it outstanding when it comes to rapid hole making.

4. Ball track machining - Roughing
To rough out the grooves, round RCMT inserts in CoroTurn® 107 are the choice to use for perfect chip breaking and high productivity.

4. Ball track machining - Finishing
The hardened grooves can be finish machined with round ceramic inserts, RCGX grades CC650 for continuous cuts and CC675 in interrupted cuts. Both grades can replace expensive grinding operations.

4. Seal groove machining
GC1125 not only runs faster and longer, it is the universal grade for all grooving and profiling operations. Improved grade technology offers a new level of machining performance , as a wider geometry range combines with the benefits of the number one profiling and grooving system, CoroCut® 1-2 edge.
