SMW Autoblok Releases Quick-Change Power Chuck

SMW Autoblok, a designer and manufacturer of rotational chucks, stationary workholding, tooling and custom engineered solutions for the machine tool industry, introduces the KNCS-2G power chuck. According to the company, the KNCS-2G enables users to change jaws in under one minute, reducing downtime during changeovers.

The KNCS-2G is said to be ideal for lathe and mill-turn applications where frequent part changes are prevalent; it features an optimized lubrication system with additional channels and grease pockets that are integrated into the jaw guide ways to enable the chuck to operate for three shifts before additional lubrication is needed. The additional sealing and new lubrication system reportedly makes the KNCS-2G suitable for mass production in all working conditions and ensures constant clamp force and extended life.

SMW Autoblok claims the wedge bar system guarantees unmatched accuracy and rigidity. In addition, a low loss of grip force due to centrifugal force compensation, along with no counterbalance weights, makes the chuck vibration-free for high-speed applications.

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

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