All services and products are performed/produced in the USA and include the designing and building of custom and standard workholding 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.

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.
