** PRODUCES GEOMETRICALLY CORRECT CENTER HOLES - A VITAL
   REQUIREMENT FOR PRECISION O.D. GRINDING.  IT IS IDEAL
   FOR RECENTERING DISTORTED CENTERS IN MACHINE SPINDLES,
   ARBORS, CENTER-CONTROLLED CHECKING DEVICES & FOR
   OTHER SALVAGE WORK.  IT MINIMIZES STOCK REMOVAL &
   GREATLY IMPROVES WORK QUALITY & ACCURACY.
   60 DEGREE CENTERS UP TO 2" DIAMETER CAN BE GROUND
   IN WORKPARTS UP TO 6" DIAMETER AND 2" TO 42" LONG.
   OPERATION OF THE BRYANT IS UNIQUE.  INSTEAD OF UTILIZING
   PLUNGE GRINDING, WITH IT'S INHERENT FAULTS, IT
   "GENERATES" TO PRODUCE FINE FINISHES & PRECISION
   TOLERANCES SIMILAR TO THOSE OBTAINED ON AN INTERNAL
   GRINDER.  
   HI-PRECISION 3-WAY GRINDING TO THE CONE-SHAPED GRINDING
   WHEELS USED. THESE MOTIONS ARE (1) ROTARY MOTION OF THE
   GRINDING CONE ABOUT ITS SPINDLE AXIS.  (2) PLANETARY
   MOTION OF THE GRINDING CONE ABOUT THE WORK AXIS.  
   (3) RECIPROCATING MOTION OF THE GRINDING CONE ALONG A
   LINE 30 DEGREES FROM THE VERTICAL.  THE GRINDING CONE
   MAKES A LINE CONTACT WITH THE CENTER HOLE SURFACE,
   WHICH SIMULTANEOUSLY RECIPROCATING ALONG THIS LINE.
   THE UNEVEN WHEEL WEAR, OCCURRING WITH REGULAR PLUNGE
   GRINDING DUE TO FULL-WHEEL CONTACT, IS ELIMINATED.
