Quick Jaw Change Lathe Chuck

Productivity, operational safety and application flexibility are enhanced by the design features of Schunk’s THW-plus, a quick jaw change lathe chuck. To meet the demands of today’s turning machines, the chuck was designed with a larger through-hole, improved grease retention and better sealing against particle and coolant intrusion. Another feature includes jaw installation safety, which is supported by an internal interlock that prevents the removal of the chuck wrench when the quick-change jaw is not properly installed.

Productivity, operational safety and application flexibility are enhanced by the design features of Schunk’s THW-plus, a quick jaw change lathe chuck. To meet the demands of today’s turning machines, the chuck was designed with a larger through-hole, improved grease retention and better sealing against particle and coolant intrusion. Another feature includes jaw installation safety, which is supported by an internal interlock that prevents the removal of the chuck wrench when the quick-change jaw is not properly installed. After proper installation, the chuck wrench is automatically ejected from the chuck body. Further, the chuck’s center sleeve is removable from the front and available in many configurations including through-hole, closed, adjustable coolant, adjustable stop and part ejector. Like the original THW model, jaws are exchanged in less than one minute, and gripping forces are maintained to 6,000 rpm with the wedge bar actuation system. With the new model, turning machines handle larger parts and require less maintenance. Setup costs are optimized with the quick jaw change and further are optimized by the ability to change the center sleeve to cover a wider application range. The safety interlock also ensures proper jaw installation.
