PRODUCT SHOWCASE: Lexair Demonstrates Full Bore Lathe Chuck at IMTS

The Production Dynamics Full Bore collet chuck from Lexair increases the through-hole capacity of lathe spindles 25-30 percent by utilizing a self-contained mechanical-grip/air-release actuation system that allows use of a lathe’s full spindle bore capacity. The chuck’s unique design eliminates the drawtube needed for hydraulic chucks, creating the additional capacity.

Demonstrated at Lexair’s booth W-1322 at IMTS, the U.S.-made Full Bore chuck ensures high machining accuracy, with concentricity adjustable from the front of the chuck. Its mechanical clamping action eliminates drawback on the stock, giving the chuck true fixed-length capability for faster, more accurate setup. The quick-acting air-release chuck, with "open-on-the-fly" capability (under 500 rpm), helps minimize cycle time and machine wear. The chuck is available in eight sizes for stock diameters of 0.25 to 5.5 inches.

The Full Bore collet chuck is self-contained and requires no actuator, opening from the front in less than a second with shop air pressure, and clamping mechanically with internal die-spring pressure. The fail-safe system delivers constant grip force at all speeds, unaffected by centrifugal force like three-jaw chucks, ensuring safe operation at high rpm. The Full Bore chuck uses standard S-style collet pads for economy.
