The Lexair Prodyne® Servo Collet Chuck is a fixed-length model designed for use with programmable bar feeder applications where accurate positioning of the stock is required. The line features a patented "pull-to-close" design that maintains the position of the bar stock against the bar feeder pusher as the chuck closes, eliminating the need to have a turret stop for positioning.

The Prodyne® series features a patented wedge design that provides and maintains high grip force regardless of spindle RPM. Our units feature a concentricity adjustment that aids to further increase the accuracy of the part being machined. The tapered nose assures that tool clearance issues are minimized and the convenient external lubrication points assure ease of maintenance and longer life. All units are supplied with a master collet that utilizes "S" style pads. Installation is effortless and employs the machine's standard drawtube plus one of our unique adapter nuts. These nuts are custom designed for your application via information supplied on a Datasheet which must be filled out prior to ordering. Click here for an inside view and to see how it works.

Lexair can supply precision machined standard collets, master collets and pads, emergency collets, serrated collets plus uniquely shaped collets by special order. In addition, bar stops and parts ejectors are available providing us the ability to be your one stop source for all your machining needs.
