Lexair Full Bore Collet Chuck
 

The Lexair Full Bore Chuck line features a fully self contained collet chuck that does not require an external actuator. Therefore, the use of a drawtube is eliminated allowing the full spindle inner diameter to be utilized with larger bar stock than can be used with typical hydraulic 3 jaw chucks.

Air pressure is used to open the chuck and release the collet. Our chuck features strong, dependable die springs (mounted in the axial, not the radial plane) to provide the mechanical grip force. Clamping force is adjustable by simply tightening or loosening the collet via spanner wrench holes in the front. When machining softer materials, the clamp force can be further reduced by easily removing pairs of springs from inside the chuck. Full Bore chucks allow higher spindle speeds as they do not have heavy jaws that can loose their grip due to centrifugal force at higher speeds.

The product line features concentricity adjustment capability for increased setup accuracy as well as visual force indicators to monitor force adjustments. The chuck body is shorter then an equal diameter 3 jaw chuck which improves tool clearance. The use of spring force to clamp the workpiece means the chuck has a true "fixed-length" grip with no drawback giving the machine operator more precise locating ability. This feature combined with the aforementioned adjustable concentricity feature allows hex, round, or square bar feeding plus fast collet or pad changes. This leads to decreases in loss of manufacturing time, increases in production time and lowers overall process/part costs. With an operation time of less then one second, our Full Bore chucks offer you the opportunity to dramatically increase machining throughput in your facility.
