"Solid Works" model of the Universal Valve Fixture illustrates valve body being clamped with tool access available from all four sides.

Berlin,CT. – Royal Machine & Tool combines the design concepts of two of their most popular fixtures…”C” Frame Fixture and Modular Fixture…into a Universal Valve Fixture. Specifically designed and developed for use in the Valve Industry, the new Universal Valve Fixture provides greater flexibility in covering a large range of Valve Bodies with a single fixture.

In making the announcement, General Manager, Guy Byrne stated, “By combining the Modular Chain Fixture with our current “C” Frame Fixture, the Independent Work Nests for specific parts are eliminated, thus reducing costs as well as improving change-over times in the process, yet maintaining positive gripping of the part(s). This new concept is ideal for families of parts as well as your odd run part.”

“In addition, our standard Royal “C” Frame Fixture is a design that cradles the part in a Work Nest which is specifically fitted to a particular part on the upper and lower portion of the fixture. Implementing the Modular Fixture as the Lower Work Nest provides ample adjustments to be made to grip many different sized parts without having to purchase custom fitted work nests that have to be unbolted each time and replaced with the correct Work Nest for an individual part number.”

Founded in 1956, Royal Machine & Tool Corporation is ISO9001:2008 & AS9100 Rev. “B” Certified and serves the world’s leading industries from its Berlin, CT corporate offices and manufacturing facility representing over 40,000 square feet including state-of-the-art CNC machine tools. All services and products are performed/produced in the USA and include the designing and building of custom and standard work holding devices from simple manual fixtures to sophisticated hydraulic fixtures with multiple faces. Custom and standard chucks of all types for rotating and non-rotating applications are also designed and built by Royal Machine &Tool…as well as a complete range of Contract Machining options/services from single prototype machining to high volume production requirements.

“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.

Royal Machine’s New Steel Bodied Manual Large Diameter Chucks are manufactured in the USA in sizes from 24” to 72” and are custom designed and built to customer specifications.

In making the announcement, Guy Byrne, General Manager, stated, “Unlike older inferior designs using Cast Iron Bodies and Scrolls that have limited wear ability, 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 New Steel Bodied Manual VTL Large Diameter Chucks are particularly applicable to the medical, aerospace, and energy technology industries.

The new clamping screw cartridge is also available on Royal’s independent adjustable jaw chucks which have been in service for a number of years.

The new QVC is designed with American Standard Tongue and Groove Master Jaws and is available in 400MM and 500MM sizes. The new design permits using existing top-tooling and “off-the-shelf standard blank jaws. Mounting features also can be supplied to the customer’s specific requirements

Royal QVC’s hold up to 8 parts and permit virtual continuous spindle use, decreased tool changes…and practically eliminate downtime for parts changeovers.

In announcing the newly designed QVC, Guy Byrne, General Manager, stated, “Older designed QVC’s required the replacement of the Master Jaw and the Adjusting Screw when thread damage occurred. With the new design, simply unfastening the old damaged cartridge and fastening in a new cartridge allows repair in the field and quickly returns the chuck to service. Thus, eliminating the possible downtime and costly expense of rebuilding. ”

Current chuck design problems virtually eliminated.

“Unlike prior chuck designs, where the thread is cut in the Master Jaw, the new design eliminates the thread in the jaw using the threaded cartridge inserted in a pocket of the Master Jaw. The problem of past chuck designs, which had the upper jaw threaded, is virtually eliminated, “ Byrne continued, ”by providing a cartridge assembly for clamping
a work piece securely and safely in a machine tool.”

“A replaceable insert, with any desirable machine-in thread, is mounted to the Upper Master Jaw. Thus, replaceable inserts may be used to accommodate adjusting screws having various complementary thread designs, including a full diameter Acme thread, in place of the square thread previously required for similar chuck designs. The Acme thread is much more economical to produce…is a stronger form of thread…and is easier to repair or replace.”

“While the Acme thread has a sloped thread side, it distributes pressure on the full diameter of the adjusting screw and is not forced into the lower operating jaw …as it would have were there only 50% contact with the upper master jaw in the
old design.”

Various alternative design options.

Design options to meet specific design requirements of the cartridge assembly include:

1. The threaded insert can be made with different style master jaws.
2. The clamping screw can be made of different materials and pitch.
3. The threaded replaceable insert may be mounted in the upper or lower jaw.

The new QVC is designed with American Standard Tongue and Groove Master Jaws and is available in 400MM and 500MM sizes. Mounting features can be supplied to the customer’s specific requirements. and the new design permits the use of “off-the-shelf” standard blank jaws or, better yet, customer’s existing top tooling. “

Royal QVC’s hold up to 8 parts and permit virtual continuous spindle use, decreased tool changes…and practically eliminate downtime for parts changeovers.

Bernie McAloon, Sales Manager, stated, “Our new QVC provides the ideal workholding solution for today’s high volume industries to meet their ever-increasing demands to manufacture high volume, uniquely shaped, varying sized quality products …on time and still be competitively priced.”
