SHIMADA CN660 CNC LATHES

Technical Description

The CNC lathe chuck is a precision workholding device engineered for high-performance turning operations on modern CNC lathes. With a 2.36-inch (approximately 60mm) chuck size, this compact unit accommodates workpieces ranging from small diameter stock to specialized shapes including round, hexagonal, and square materials. The chuck delivers 7.37 horsepower of clamping force, ensuring secure workholding across diverse machining applications while maintaining minimal vibration and runout. Rated for a maximum operational speed of 3,000 RPM, this power-operated chuck is precision-balanced to minimize dynamic effects and vibration during high-speed turning operations. The CNC control integration enables automated jaw actuation, facilitating rapid workpiece loading and unloading while optimizing production cycle times. The chuck features power-operated three-jaw configuration with automatic centering capability, providing large clamping range and fast clamping speed suitable for both finished and unfinished workpiece surfaces. Key technical characteristics include hardened jaw surfaces for enhanced wear resistance and rigidity, with standard options for both external and internal clamping applications. The through-bore design, common in modern CNC chucks, allows bar stock feeding for continuous production runs. Construction prioritizes low inertia and compact design to positively influence CNC machine spindle dynamics. This chuck class represents industry-standard precision workholding, delivering concentricity within tight tolerances for applications demanding superior accuracy and repeatability in turning operations.
