New Royal Machine Manual VTL Chucks Provide Close Tolerances Capabilities Required in Machining of Thin-Walled Products

In making the announcement, Guy Byrne, General Manager, stated, “Unlike older inferior designs using Cast Iron Bodies and Scrolls that have limited wear ability, our new design boasts superior steel strength, induced wear resistant body, hardened and precision ground Master Jaws and Wedge.”


Karol Ziecina, Machine Specialist at Atlas Precision Manufacturing in South Windsor, CT prepares chuck top tooling on a 32” diameter 3-jaw manual chuck.

“This produces increased accuracies and wedge style gripping forces where it is pertinent to hold precision and close tolerances in the machining of parts and  products made of exotic materials with thin-walled geometries.”

In addition, 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.

Byrne further stated, “These specific features and applications of our “Next Generation” design of Manual VTL Large Diameter Chucks are of particular interest and importance to specific industries such as.. Aerospace…Medical…Bearings…Energy & Technology.

All Royal Machine 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.

Manufactured in the USA, the large load bearing surfaces of all Royal Machine Large Size Power Chucks reduce wear, increase accuracy and extend service life. 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.

Specifically, Large Diameter Chucks are offered with additional jaw configurations and are available:

  • in Direct Mount to American Standard  ASA B5.9 Type A1, A2, B1, B2, DIN55026-1, DIN-55021-A, and ISO R 702-1 spindles.
  • with American Standard Tongue and Groove or American Standard Acme Serrated Master Jaws.
