SMW Autoblok has introduced its HFKS-2G weight-optimised power chuck with flats and large through-hole for minimising inertia, maximising part accessibility, and saving wear and tear on the spindle.

Suitable for high-volume lathe and turn-mill centre applications, the HFKS-2G is optimised for the heavy-duty precision machining of easily deformed workpieces, including the gripping of both ID and OD 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.
The HFKS-2G features a proprietary wedge hook mechanism combined with a multi-jaw guide, which multiplies the points of contact and provides added surface connection and stability. In addition, the specially designed guidance system features inclined geometry that locks the master jaw mechanically after clamping against the chuck body and 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 with other industry three-jaw chucks, reports the company.
Direct lubrication channels and grease reservoirs integrated in the jaw guideways ensure constant clamp force and improved accuracy and durability, even in harsh industrial environments. The specially designed lubrication system also minimises downtime and reduces maintenance costs.
HFKS-2G chuck body and internal parts are case-hardened and polished for increased life. Available in a variety of sizes from 210-320 mm, the power chuck accepts all inch serrated top jaws.
