"S" Pad Collet Chuck Overview MicroCentric introduces a new line of Collet Chucks for "S" Style Collet Pads. The MicroCentric design is based on a vulcanized master collet which allows the chuck to be shorter than designs using conventional spring type master collets. Shorter chuck length promotes increased rigidity and enables full use of a machine's Z axis. The MicroCentric master collet also produces a parallel clamping action that results in higher chucking forces. This feature together with greater rigidity permits heavier cuts and improves tool life. Low Profile Design • Short overall length...

MicroCentric "S" Pad Collet Chuck Models All components of MicroCentric Collet Chucks are made from hardened and precision ground alloy steel for high accuracy and unsurpassed long term performance. Their modular design makes it possible to adapt MicroCentric chucks to all machine spindle nose and draw tube configurations. NB/S Series - Pull Back Design In the CB-NB/S series collet chuck, the master collet is coupled directly into the draw tube connector. As the draw tube is actuated, the master collet is drawn into the tapered seat of the chuck body, efficiently translating draw tube force into...

CB-NB/S Collet Chucks - Pull Back Design In the CB-NB/S series collet chuck, the master collet is coupled directly to the draw tube connector. As the draw tube is actuated, the master collet is drawn into the tapered seat of the chuck body, efficiently translating draw tube force into maximum clamping force. CB-NB/S Features • Pull Back design maximizes the efficiency of the clamping system by concentrating all forces in the direction of the spindle for highest accuracy and greatest overall rigidity • Low profile OD and short overall length provides increased tool clearance and maximum utilization...

CB-ND/S Collet Chucks - Dead Length Design In the CB-ND/S series collet chuck, the master collet is coupled to the chuck body and remains stationary as the tapered seat moves forward during clamping. This design keeps the collet in a fixed Z axis position as the chuck is actuated, and does not create a pull back effect on the bar. CB-ND/S Features • Dead Length design produces no pull back on the workpiece • Low profile OD and short overall length provides increased tool clearance and maximum utilization of the machine's Z axis travel compared to conventional master collet chucks • Radial adjusting...

CB-NDR/S Collet Chucks - Pull to Close Dead Length Design for Servo Bar Loaders The CB-NDR/S series collet chuck is a new patented Dead Length design for use with servo stop bar loaders. The chuck is actuated as the draw tube is pulled into the machine spindle. The master collet is coupled to the chuck body and remains stationary as the tapered seat moves forward during clamping. This feature keeps the collet in a fixed Z axis position, and since the draw tube is moving into the spindle, the bar remains positioned against the servo stop. CB-NDR/S Features • Pull to Close Dead Length design produces...

CB-NS/S Collet Chucks - Sub Spindle Design The CB-NS/S series is a low profile dead length collet chuck designed especially for sub spindle applications. The master collet is coupled to the chuck body and remains stationary as the tapered seat moves forward during clamping. This design keeps the collet in a fixed Z axis position as the chuck is actuated, and does not create a pull back effect on the bar. CB-NS/S Features • Dead Length design produces no pull back on the workpiece • Reduced chuck OD for maximum clearance on sub spindles • Short overall length provides increased tool clearance...
