Shorter Setup Times with Quick Jaw Change Chuck

With the ROTA THWplus chuck from Schunk a complete jaw set can be changed in less than 60 seconds with a repeatability of less than 0.0005 in, which eliminates the need to re-bore jaws.

The ROTA THWplus quick jaw change chuck from Schunk USA Inc. (Morrisville, NC) stands alone in flexibility and set-up efficiency. In today’s competitive manufacturing world, single purpose chucks will not stand the demanding changes.

In less than 60 seconds, a complete jaw set can be changed with a repeatability of less than 0.0005 in, which eliminates the need to re-bore jaws. A unique wedge-bar actuation system allows this chuck to offer larger through holes with faster spindle speeds, coupled with the Quick-Jaw-Change-System. The ROTA THWplus increases time in the chip, not in the set-up, which maximizes the throughput and ROI of any lathe.

A selection of modular sleeves are available for through spindle coolant, part ejection, closed center sealing, or as an adjustable part stop, giving you the flexibility you need in all process improvements. This quick jaw change chuck was designed with safety in mind. To avoid damage to the machine and danger to the operator the actuation wrench can only be removed when a jaw is properly engaged. The chuck is available in the sizes 165, 185, 215, 260, and 315.
