What is the Parent-Child Jaw System?

NC lathes have chucking devices, such as the three-jaw chuck. One of the options is the parent-child jaw system. This system consists of a parent jaw and a child jaw, where the child jaw is bolted onto the parent jaw.

Benefits of the Parent-Child Jaw System

Variety and Small Quantities: The parent-child jaw system is suitable for a variety of small quantity productions. By replacing the child jaw without removing the parent jaw, the diameter of the gripping part can be changed, allowing for a wide range of workpieces to be held.
Improved Setup Efficiency: The setup efficiency is significantly improved as only the child jaw needs to be replaced.
High Maintenance Efficiency: The child jaw can be treated as a spare part, allowing for low-cost operation even if the child jaw is damaged, without affecting the parent jaw.
