A collet can provide certain advantages over a jaw chuck, vise and other clamping methods.
* The advantages of using Collet Blocks when compared with standard vices or three-jaw chucks - Hardinge informed Manufacturingtalk that a collet automatically centres the workpiece for reduced set-up time.
Centres remain fixed when the fixture is removed from the machine table.
A collet provides equal gripping pressure around the circumference of the part unlike a standard vice or a three-point contact jaw chuck.
Thin-wall parts or delicate materials may crush or distort in a standard vise or jaw chuck.
Collets ordered with serrations can add additional gripping power to prevent push-back and radial slipping.
Extended-nose collets can provide additional tool clearance.
Some collet blocks accept expanding collets to grip a part at the internal diameter.
Director of Sales and Marketing, Hardinge Workholding, Cal Macomber, told Manufacturingtalk: "We see collet block applications in the standard job shop including milling, drilling and grinding - but also in the crimping, inspection, testing and assembly environments.".
