GENERATION II DESIGN CONCEPTS

The major reason for the tremendous success of the Wedge Chuck System is the patented Rocking Wedge as illustrated . Please note the angles and radii which permit them to rock free.

 

G II Wedge Chucking System

Design improvements to the patented Wedge Chuck
Assembly facilitate smother closing action and
insure the greatest holding capacity.

A simple change to the form of a radius substituted for an angle on the Inner Sleeve (NP-100-3-R)
coupled with a New Wedge design has producedthe
NOWAK GENERATION II WEDGE CHUCK ASSEMBLY
NP-100-R

The GII is the
most efficient and productive chucking sysem known.
