Wheeling, Illinois – 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 TX Series 3-jaw pull-down chucks featuring repeatability of up to 4µm (0.00015") and precise, self-centering accuracy for heavy duty metal cutting applications.

The TX Series features the TX-C (tongue and groove) and TX-RV (quick jaw change) models. Both versions are ideal for first and second operation while providing exceptional parallelism.

A unique symmetrical master jaw design that disperses cutting forces over a wide area allows the chucks to hold their accuracy for a long lifetime to ensure constant workpiece quality. The master jaw design also allows for I.D. and O.D. gripping with optimal stability and no changes that regular ball lock chucks require. Integrated centrifugal force compensation provides constant clamp force at higher speeds and feeds, vastly reducing production time.

The TX Series is fully Proofline sealed for greatly reduced maintenance and will run 24/7 for 6 months without adding additional lubrication. The TX-RV model features a unique quick-change top jaw for part families and both TX models have active pull-down for enhanced plane parallelism. The chucks are available in size ranges of 170mm, 210mm, 250mm, 315mm, 400mm, and 530mm.
