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.


  • A Study Of The Steady Rest

    When the length and stiffness of a workpiece make it difficult to machine, many turn to the steady rest.

  • Multitasking's "Big" Advantage

    As demonstrated at this Cincinnati-area shop, machines that both mill and turn shine brightest when workpieces are massive.

  • Pins: The Alternative To Parallels

    These vise jaws use protruding, mechanical pins to repeatedly support workpieces either horizontally or at angles. They are said to allow quicker setups than conventional parallels.
