Manual VTL Chucks

January 01, 2011

Royal Machine & Tool Corp.'s steel bodied manual VTL large-diameter chucks are manufactured in the USA in sizes from 24" to 72" in diameter and are custom designed and built to customer requirements. In making the announcement, Guy Byrne, General Manager, stated, "This new design boasts its superior steel strength, induced wear resistant body, hardened and precision ground Master Jaws and Wedge."

This produces increased accuracies and wedge style gripping forces. Aside from these benefits, this "next generation" design uses a readily replaceable pinion gear for added torque and also has improved chip protection to help reduce contamination and downtime for maintenance. These chucks are particularly applicable to the medical, aerospace, and energy technology industries. All large-diameter power chucks are now available in standard 2-Jaw, 3-Jaw, 4-Jaw and a combination 2/3-jaw configuration with both adjustable and non-adjustable Master Jaw styles as well as special requirements for 6- or 12-jaw and self-contained applications.

Easy-access lubricating fittings in each master jaw and chuck body provide lubrication for all wearing surfaces. In addition, the large diameter chucks' basic design maximizes chip and coolant protection.

Related Glossary Terms

  • chuck


    Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.

  • coolant


    Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
