Power chuck BUCK

quick-changehigh clamping forcepower-operated

Overview
High-precision universal-application power chuck. The BUCK power chucks deliver precise, repeatable gripping across a wide range of turning operations. Lightweight construction supports higher spindle speeds. Optional quick-change jaw systems reduce setup and changeover time, decreasing cycle times, energy consumption and spindle wear.

Performance & Applications
The BUCK chuck family provides increased clamping force and high precision, suitable for heavy-duty machining of disk and bar components and for finish machining of easily deformed workpieces. Available jaw options conform to industry standards in the US, Europe and Asia to simplify tooling procurement.
