SMW Autoblok’s Fully Sealed Pull-Down Chucks Feature High Accuracy, Heavy-Duty Gripping

By SMW Autoblok Press Release

Wheeling, IL – SMW Autoblok, a designer and manufacturer of rotational chucks, stationary workholding, tooling and custom engineered solutions for the machine tool industry, has introduced the TX Series 3-jaw pull-down chucks featuring repeatability of up to 4 µm (0.00015”) and precise, self-centering accuracy for heavy duty metal cutting applications.

The TX Series three-jaw pull-down chucks from SMW Autoblok.

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 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, according to the company. 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 Proofline sealed for greatly reduced maintenance and will run 24/7 for 6 months without adding additional lubrication, according to SMW Autoblok. The TX-RV model features a 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 170, 210, 250, 315, 400 and 530 mm.
