Wheeling, IL – 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 center applications, the HFKS-2G is optimum for heavy duty precision machining of easily deformed workpieces including gripping of both I.D. and O.D. part geometries. As a result of specially designed flats on the chuck body, the ability to use shorter tools to gain closer access to workpieces provides added part 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. The specially designed guidance system features inclined geometry that locks the master jaw mechanically after clamping against the chuck body and dramatically reduces jaw movement.

This multi-jaw control, along with the integrated centrifugal force compensation, enables significantly higher speeds and delivers twice 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 and durability, even in the harshest industrial environments. The specially designed lubrication system also minimizes downtime and reduces maintenance costs.

The HFKS-2G chuck body and internal parts are case hardened and polished for increased life and the highest rigidity and durability. Available in a variety of sizes from 165-320 mm, this advanced power chuck accepts all inch serrated top jaws.
