BODY
- type KG11,KG12 chucks - drop-forged of highest grade steel, hardened and ground
- type K11, K12  chucks - high quality cast-iron
SCROLL PLATE
- drop-forged of fi ne alloy steel, carburized and hardened
- thread fl anks ground on both sides
JAWS
- of fi ne alloy steel, teeth, guides and other working surfaces carburized, hardened and ground
PINIONS
- of alloy steel, carburized, hardened and ground

- pinions are recessed into the chuck body and special safety spring is mounted on the operating wrench preventing against the risk of accidents
Each scroll plate and assembled precision chuck are statically balanced within fi ne limits.
Lathe chucks must be lubricated regulary to maintain their gripping force.
