One Closer, Four Work Holding Systems

Versatile and efficient Flex Grip closers from Lexair Inc. (Lexington, KY) can boost productivity in a variety of machining operations – including 4-axis, 5-axis, rotary indexer and stationary applications – by reducing set up times with 10 second collet change capability and .0002 in part accuracy. These manual/hydraulic closers are clamped through a screw pump with a spring return opening. A parts stop disk is inserted and removed from the top to eliminate the need to remove the closer from the mounting base. The closers can also be equipped to operate under M-code command for fully automated applications. With the addition of a Hardinge 5C and 16C tooling adapters, Flex Grip closers can be used with Hardinge FlexC™ collets and Sure Grip ID mandrels, 5C and 16C collets, as well as 5C and 16C step chucks, providing four working holding options in one collet.

Flex Grip closers are available in sizes of 65 mm and 80 mm and grip force up to 21,600 lb at 65 lb/ft. The collets can be custom-fitted to nearly any application and, according to Lexair, testing has yielded .0002 in part accuracy with ±.020 in range on part diameter and a 10 second collet change.
