Change Jaws in Less than 1 minute with the KNCS-2G Power Chuck

25 October 2021

Wheeling, IL – Introducing the flexible, fully Proofline® sealed KNCS-2G power chuck that allows users to change jaws in under 1 minute – dramatically reducing downtime during changeovers which saves companies both time and money.

Ideal for lathe and mill-turn applications where frequent part changes are prevalent, the KNCS-2G features an optimized lubrication system with additional channels and grease pockets that are integrated into the jaw guide ways to allow the chuck to operate for three shifts before additional lubrication is needed. The sealing and new lubrication system makes the KNCS-2G suitable for mass production and ensures constant clamp force and extended life.

The proven wedge bar system guarantees unmatched accuracy and rigidity. Plus, a low loss of grip force due to centrifugal force compensation, along with no counterbalance weights, makes the chuck ideal for high-speed application with no vibration.

The chamfered guide ways of the KNCS-2G are designed to allow for quick-change of jaws, making it flexible for operations needing multiple jaw changes and setups. The fully Proofline® sealed chuck body and base jaws also provide additional protection against chips, lubricants and other debris.

The chuck body and internal parts are case hardened for increased chuck life and highest rigidity, precision and durability. The KNCS-2G is interchangeable with our standard KNCS-N chucks and existing master jaws can still be used without sealing. Sizes are available in 170-630 mm.
