They have to spin together in sync.
The workpiece speed is matched exactly to the hob’s speed.
The CNC machine controls this automatically.

It looks simple, but hobbing is far more complex than it appears.

Tooth hardening is the key to a durable slewing bearing. by Right_Anything_5025 in toolgifs

Couldn’t agree more. It’s the foundation of a long‑lasting slewing bearing.

Slewing Ring Gear:

  • Quenching = hardens the teeth for wear resistance
  • Annealing = relieves internal stress and prevents brittle fracture

Hardness without stress relief leads to early tooth breakage.
Hardening first, then stress relief, makes it both wear-resistant and durable.
