SMW Autoblok says its TX Series three-jaw pull-down chucks feature repeatability of up to 4 µm (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. SMW Autoblok recommends both versions for first and second operations, saying they provide exceptional parallelism for each.

A unique symmetrical master-jaw design disperses cutting forces over a wide area, allowing the chucks to hold their accuracy for a long lifetime and ensuring constant workpiece quality. The master jaw design also allows for inner diameter (ID) and outer diameter (OD) gripping with optimal stability and without the changes that regular ball-lock chucks require. Integrated centrifugal force compensation provides constant clamp force at higher speeds and feeds, reducing production time.

The TX Series is Proofline-sealed to reduce maintenance, and the company says these workholders will run 24/7 for six 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 170, 210, 250, 315, 400 and 530 mm.
