Berlin, CT – In announcing the newly designed and patented Adjustable Cartridge Jaw, Guy Byrne, Senior Vice President & General Manager, stated, “Older designs 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 easier on site repair and quickly returns the fixture to service.”

In addition, the new design provides improved accuracy and greater gripping force because of its centralizing 29 degree angular contact Acme threaded screw and bronze bushing.”

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.”
