SMW Autoblok, a world leader in the design and manufacture of rotational chucks, stationary workholding, tooling and custom engineered solutions for the machine tool industry, introduces the HFKS-2G weight optimized power chuck with flats and large through hole for minimizing inertia, maximizing part accessibility, and saving wear and tear on the spindle.

Ideal for high volume lathe and mill turn applications, the HFKS-2G is optimum for heavy duty precision machining of easily deformed workpieces. Thanks to flats on the chuck body technology and lighter weight, the ability to use shorter tools to gain closer access to workpieces provides added parts precision and cost efficiency.

Unique to the HFKS-2G is the wedge hook mechanism combined with multi jaw guide, which multiplies the points of contact and provides added surface connection and stability. This specially designed guidance system features inclined geometry that locks the master jaw mechanically after clamping against the chuck body and dramatically reduces jaw movement.

The integrated centrifugal force compensation enables significantly higher speeds and delivers double the grip force at maximum RPM compared to other industry 3-jaw chucks. Direct lubrication channels and grease reservoirs integrated in the jaw guideways ensures constant clamp force and improved accuracy even in harsh machining environments. This specially designed lubrication system also minimizes downtime and reduces maintenance costs. The chuck body and internal parts are case hardened for increased chuck life and highest rigidity, precision and durability. This advanced power chuck accepts inch serrated top jaws and is available in sizes from 165-320 mm.
