Worm gears are typically made from:
The worm is rough machined, carburized, hardened, and then submitted to finished grinding.
We can manufacture from 1 up to 6 single or multiple start worms with a right- or left-hand lead.
Carnes-Miller Gear can reverse engineer a worm and worm gear set when both items are provided. The tooth geometry for the worm gear comes from the worm. In a reverse engineering situation, the worm provides the tooth geometry for the worm gear.
Worm hobs available: both metric and English units. This often allows us to avoid tool up-charges.
