BARBER COLMAN MODEL 16-36 "MULTICYCLE" UNIVERSAL GEAR HOBBER
MANUFACTURED
STOCK# 80143

 THIS BARBER COLMAN MODEL 16-36 GEAR HOBBER IS MADE TO PERFORM ALL
 CUTTING MOTIONS IN EITHER AUTOMATIC SQUARE-CUT OR PLUNGE-CUT CYCLES.
 IT CAN PRODUCE WORM GEARS AS WELL AS SPUR AND HELICAL GEARS AND SPLINE
 SHAFTS WITH FULLY AUTOMATIC OPERATIONAL EFFICIENCY, WITHOUT THE
 OPERATOR'S ATTENTION.  ALL THAT IS REQUIRED OF THE OPERATOR IS THE
 LOADING OF THE BLANKS, THE PRESSING OF THE START BUTTON, AND THE
 REMOVAL OF THE FINISHED PARTS.
 THIS MACHINE IS OF THE MORE MODERN DESIGN, WITH AN EXTENDED OVERARM
 TO ALLOW HOLDING OF LONGER PARTS BETWEEN CENTERS, A 4-1/8" WORK SPINDLE
 BORE, AN AUTOMATIC HOBSHIFT FOR EXTENDED TOOL LIFE, AND ANTI-FRICTION
 BEARINGS IN BOTH THE WORK SPINDLE AND HOB SPINDLE.
 THE MACHINE IS IN EXCELLENT CONDITION, HAVING BEEN USED IN THE SHOP
 OF A HIGH QUALITY GEAR MANUFACTURER, WHERE IT HAS BEEN REGULARLY AND
 PROFESSIONALLY MAINTAINED.  IT WAS AN INTEGRAL PART OF THE REGULAR
 PRODUCTION OPERATIONS, UNTIL THE ENTIRE GEAR DEPARTMENT WAS CLOSED,
 MAKING THIS FULLY FUNCTIONAL MACHINE AND OTHERS AVAILABLE.
