| Royal Machine’s new steel bodied manual large-diameter chucks are manufactured in sizes from 24 to 72 in., and are designed and built to customer specifications. |
According to Royal Machine general manager Guy Byrne, the company’s new VTL chuck has superior steel strength, an induced wear-resistant body, and hardened, precision-ground master jaws and wedge. These factors increase the chucks’ accuracy and wedge-style gripping forces. Aside from these benefits, the supplier indicates its “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.
Royal Machine indicates the new steel-bodied, large-diameter manual VTL chucks are particularly applicable to the machining components parts for medical, aerospace, and energy technology sectors. All large-diameter power chucks are available in standard two-jaw, three-jaw, four-jaw, and a combination two/three-jaw configuration, with both adjustable and non-adjustable master jaw styles, as well as special requirements for six or 12-jaw and self-contained applications.
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; and with American standard tongue and groove or American standard Acme serrated master jaws.
The supplier emphasizes that the large load-bearing surfaces of all its 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. And, the large-diameter chucks’ basic design maximizes chip and coolant protection.
