The Duro-NCSE Flex power chuck from Röhm Products of America provides a quick, simple way to change out jaws and clamping tools. The chuck system enables switching between mandrels, collet chucks, face drives and centers without needing to remove the power chuck from the machine tool.
The Duro-NCSE Flex works like a standard three-jaw chuck but features a bayonet-style connection so that only an attachment system is changed to switch clamping devices. A case-hardened steel chuck features individual unlocking jaws that can be easily moved, changed and turned. According to the company, the chuck provides accurate holding, precise gripping and dependable performance, especially in high-speed applications.
The chuck is well-suited for short-bar-feeding applications (4 ft.) because it provides increased support at the machine tool spindle, the company says. The chuck reduces the amount of preparation cutting needed, as well as material waste. An added dead-length collet chuck generates more support for longer sections of barstock. Variations within the series include the Duro-NCSE Flex KZZT/KZZT-A collet chuck and Duro-NCSE Flex ABSIS mandrel models, both of which provide part-deformation-sensitive workholding to accommodate thin-walled parts.
