The Lexair Full Bore Chuck is a self-contained, mechanical grip, air release front actuated collet chuck. The chuck does not require an external actuator. Air is used only to open the chuck. Spring force holds the workpiece while it is being machined. Thus, the part remains clamped, even if air pressure is lost. Higher spindle speeds are available since a collet chuck does not have heavy jaws that lose grip force as the spindle speed of the machine increases. Clamping force is adjustable by tightening or loosening the collet using the spanner holes in the front of the collet. The clamp force can also be reduced by removing pairs of springs inside the chuck. The chuck does not require a draw tube, allowing the full inner diameter of the spindle to be utilized.

The gland and gland housing are used to transmit the air to the chuck. When the spindle is stopped and the chuck is opened, a valve admits air into the gland housing, pushing the gland forward against the back of the chuck. The face of the gland seals against the chuck body and allows air pressure to build inside the chuck, forcing the piston forward. The rollers drop back, allowing the pusher to move back and release the collet. When the chuck is closed, the air in the gland housing is vented to the atmosphere. The gland then retracts from the chuck body, and the springs and wedging action of the piston, ramp, rollers, and pusher close the collet on the part.

dIrECT MOUNT Pull Back Collet Chucks The Lexair Direct Mount Collet Chucks offer a simple and economical way of holding material for turning when using “C” or “J” style collets.
Our small body helps to increase tool clearance and lower the weight of rotating mass. This feature both relieves stress on the spindle bearings and lowers the time needed for acceleration or deceleration which means more time for production of parts. The rigid 360° clamping action allows for increases in spindle RPM’s without loss of clamping force. These units are an excellent choice for clamping small diameter parts, for bar feed applications, and when better accuracy is desired. The “5C” chucks feature a standard threaded nose providing step chuck capability.

dISCONNECT HANdLEThe patented Lexair disconnect handle quickly and conveniently allows for connection/disconnection of hydraulic lines to/from machine tool pallets or other hydraulic applications. Designed for use in double acting applications, the unit automatically latches when pressure is present on either hose preventing accidental disconnects. Our ergonomic design helps minimize operator hand fatigue. Pallet disconnects can be integrated with all Lexair hydraulic collet closers and must be used with a momentary hydraulic pump or a 3-position, 4-way valve in conjunction with a pilot operated check valve.
Please contact Lexair to get the correct plumbing arrangement for your application.
