Diagram & Description

The patented Wedge Chuck Assembly is a direct replacement and upgrade for the Acme-Gridley finger holder assembly. All Nowak Wedge Chuck Assemblies are unparalleled in performance and longevity in addition to being competitively priced.

Features and Benefits:

  • Patented wedge design insures full circle contact and equal drawing pressure on the collet tube and collet resulting in improved concentricity.
     
  • Angles and radii of matched set of wedges ride on the radius of the removable wear ring. Matching radius to radius allows the wedges to rock free when the collet tension is released.
     
  • Centrifugal force of the spindle engages the holding pins that prevents the outer housing from moving forward and wearing spool cam and guard.
     
  • Pressure collar design permits more precise collet tension adjustment due to increased number of adjustment holes on pressure collar face.
     
  • Removal of the plug screw from the outer housing permits periodic lubrication of the unit without having to remove the entire assembly from the spindle.
     
  • Field testing and use has proven minimal component wear and replacement required after years of service.
     
  • All size ranges are shipped completely assembled and prelubricated for immediate installation.
