    CB-NX Collet Chuck- Dead Length Design

     

    The CB-NX series is a low profile dead length design with a reduced diameter nose for maximum tool clearance. The collet is coupled directly to the chuck body and remains fixed as the tapered seat moves forward when the chuck is actuated. The collet remains fixed in the Z axis during clamping and therefore does not create a pull back effect on the bar stock or workpiece.

    CB-NX Features

    • Low Profile Dead Length design
    • Reduced diameter nose and short overall length provides increased tool clearance and maximum utilization of the machine's Z axis
    • Radial adjusting screws to true-up tapered collet seat within .0002” (0.005mm)
    • Lubricated-for-life design requires minimal maintenance
    • All components hardened and precision ground for highest accuracy and long life
    • Stop plates, stop housings, and ejectors can be mounted inside the chuck body for chucking applications

  • CB-NDR Collet Chucks - Pull to Close Dead Length Design for Servo Stop Bar Loaders

    CB-NDR Collet Chucks - Pull to Close Dead Length Design for Servo Stop Bar Loaders

     

    The CB-NDR is a patented Dead Length design for use with servo stop bar loaders. Unlike conventional dead length collet chucks, the NDR is actuated as the draw tube is drawn toward the machine spindle to prevent the bar from being pushed off the servo stop.

    CB-NDR Features
    • Pull to Close Dead Length design produces no pull back and will not push the bar off the servo stop
    • Radial adjusting screws to true-up the chuck assembly within .0002” (0.005mm)
    • Lubricated-for-life design requires minimal maintenance
    • All components hardened and precision ground for highest accuracy and long life

     

     
  • CB-NK Collet Chucks - Combination Design

    CB-NK Collet Chucks - Combination Design

     

    NK series chucks are a pull back design with the added flexibility of being able to mount end stops inside the chuck body for easy conversion from bar to chucking applications. The collet is coupled directly to the draw tube connector. As the draw tube is actuated the collet is drawn into the tapered seat efficiently translating draw tube force into maximum clamping force.

    CB-NK 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 of the machine's Z axis

    WSF Collet Chucks - Retractable Design

     

    Shafts can be machined complete between centers with MicroCentric's retractable collet chuck. A face driver mounted in the ID of the chuck drives the shaft as it is supported by the tailstock to turn the end of the shaft. When the chuck is actuated the collet moves forward to clamp the turned diameter enabling the OD of the shaft to be machined completed while the end of the shaft is securely clamped.

    WSF Features

    • Mounting for face driver in ID of chuck assembly
    • Radial adjusting screws to true-up chuck assembly within .0002” (0.005mm)
    • All components hardened and precision ground for highest accuracy and long life

 

CB-NX Collet Chuck- Dead Length Design

 

 
 
  • CB-NX picture
 

The CB-NX series is a low profile dead length design with a reduced diameter nose for maximum tool clearance. The collet is coupled directly to the chuck body and remains fixed as the tapered seat moves forward when the chuck is actuated. The collet remains fixed in the Z axis during clamping and therefore does not create a pull back effect on the bar stock or workpiece.

CB-NX Features

  • Low Profile Dead Length design
  • Reduced diameter nose and short overall length provides increased tool clearance and maximum utilization of the machine's Z axis
  • Radial adjusting screws to true-up tapered collet seat within .0002” (0.005mm)
  • Lubricated-for-life design requires minimal maintenance
  • All components hardened and precision ground for highest accuracy and long life
  • Stop plates, stop housings, and ejectors can be mounted inside the chuck body for chucking applications
