		First Operation Collet Chucks Typically used for barfed lathes or slugged bar. Higher Spindle Speeds than standard 3-jaw chucks Holds grip force at higher speeds Compact design has less mass allows for faster ramp up/down Better repeatability than standard chucks More tool clearance Quicker size/shape changes




		Second Operation Collet Chucks Use these chucks on shaft or long parts that need a short cycle times and tight tolerances More Accurate than standard 3-Jaw Chucks Positive length control and parrallism with pullback action Air sensing and through spindle coolant capable Holds gripping force at higher speeds Less maintenance and cleaning than a standard chuck Hardened and ground components for longevity




		Swivel-Grip Chuck (5) Castings and forgings are held securely for this first operation machining chuck. Jaws swivel up to six degrees to compensate for part irregularities and tapers. Pullback feature provides maximum rigidity and length positioning. Two, three and six-jaw, self-centering or compensating models available. Can be arranged for internal and external gripping. Double sealed against chip contamination. Top jaws and workstops designed to suit.




		Drawdown Chucks (5) Primarily second operation turning to grip on machined surfaces without marring the finish Jaw/post assembly designed to compensate for out-of-round parts Pullback feature provides positive length control and parallelism More accurate than conventional chucks (.0005" T.I.R.) Top jaws designed to suit, with or without grippers Air sensing and thru spindle coolant capable Three and six-jaw styles available




		Hydraulic Expanding Chucks When High precision chucking is required for Grinding , turning, inspecting, or balancing the hydraulic membrane chuck is ideal. Repeatability within .0002" TIR as standard and up to .00005" TIR for critical applications. Completely sealed against contamination Grips multiple parts and/or multiple diameters Collets allow for size quick change Manual or power operated.




		Diaphragm Chucks Primarily used for second operations including grinding. No sliding parts to wear out No contamination Pullback action Light clamping for thin walled parts Single or double acting Counterweights available for higher RPM TIR .0002” repeatability




		Compensating Chucks Accomodates clamping diameters that are out of round or are not concentric with the locating datum Drawbar or hydraulic actuation. Sealed against contamination Pullback or dead length designs Grips thin walled parts or parts with centers




		Shaft Chucks Jaws extend and retract to enable the turning of the complete shaft in one operation. Heavy cuts can be made without slippage by extending the jaws to clamp the shaft. Jaws retract out of the way and the facedriver is used for final turning. Jaws compensate for part irregularities. Jaws are designed to meet customer's specific machining Leeds. Facedrivers can be changed for different sized shafts. Driver pins mechanically compensate for out-of-square parts while the spring-loaded center compensates for center size variations. Standard or special chuck designs available. Chuck is sealed to prevent contamination




		Gear Chucks Locate on your part's pitch diameter accurately for turning, milling, grinding and inspection applications. Whether the gear or spline is cut or formed on the inside or outside diameters - straight or helical bevel gears Collet arbors and chucks, Hydraulic expanding arbors and chucks, Rotary locking splines, bevel gear chucks, Specials that have unique advantages suited to your application.
