ROLLER BURNISHING TOOLS FOR DAVENPORT, CNC AND OTHER SCREW MACHINES

IMPORTANT:

FOR BURNISHING TOOL TO FUNCTION AS DESIGNED THE FOLLOWING RULES MUST BE OBSERVED:

INSERT SLIDE BODY (PT. 2) MUST BE ADJUSTED FOR ALIGNMENT WITH MACHINE SPINDLE AND LOCKED IN PLACE WITH HEX SCREWS (PT. 14).

WHEN MAKING DIAMETER ADJUSTMENTS, LOCKING RING (PT. 7) MUST BE SNUG, BUT NOT SO TIGHT THAT ROLL SLIDES CAN NOT BE ADJUSTED FOR DIAMETER.

DIAMETER ADJUSTMENTS OF THE MICROMETER SCREW (PT. 8) MUST BE MADE IN THE CLOCKWISE DIRECTION (CLOSING DOWN) SO AS TO ELIMINATE BACKLASH.

WHEN CORRECT DIAMETER IS ATTAINED LOCKING RING MUST BE FULLY TIGHTENED USING THE SPANNER WRENCH (PT. 18) PROVIDED.

--------------------------------------------------------------------------------------

TO INTERCHANGE ROLL SLIDES:

REMOVE STOCK STOP PLATE BY REMOVING TWO SCREWS IF APPLICABLE.

LOOSEN LOCKING RING (PT. 7) WITH SPANNER WRENCH (PT. 18) PROVIDED.

UNTHREAD LOCKING RING (PT. 7) COMPLETELY AND REMOVE.

REMOVE 3 SLIDE CLAMPS (PT. 4) AND 3 ROLL SLIDES (PT. 5 OR 5A).

REPLACE WITH DESIRED SIZE ROLL SLIDE (SLIDES ARE MARKED WITH DIAMETER RANGE) BEING CERTAIN THAT SLIDE PIN IS IN THE SCROLL GROOVE AND SIDE IS PROPERLY SEATED IN DOVETAIL.

REPLACE 3 SLIDE CLAMPS.  REINSTALL LOCKING RING AND TIGHTEN UNTIL IT IS SNUG, BUT NOT SO TIGHT THAT ROLL SLIDES CAN NOT BE ADJUSTED FOR DIAMETER.

ADJUST SLIDES TO .001" TO .002" LARGER THAN DESIRED DIAMETER BY ROTATING MICROMETER SCREW (PT. 8) AND CLOSING ROLL SLIDES DOWN SO THAT ROLLS ROTATE FREELY ON A ROD OR GAGE OF THAT DIAMETER.

BE SURE THAT LOCKING RING IS VERY SNUG AND TAKE A TRIAL PASS.  CHECK BURNISHED DIAMETER AND MAKE FURTHER ADJUSTMENTS AS NECESSARY UNTIL DESIRED FINISH IS ATTAINED.  THEN FULLY TIGHTEN LOCKING RING USING THE SPANNER WRENCH PROVIDED.

NOTE THAT EACH LINE ON MICROMETER SCREW = .001" ON DIAMETER (.0005" ON THE SIDE), AND THAT ALL THREE SLIDES ARE ADJUSTED SIMULTANEOUSLY.

WARNING: LOCKING RING (PT. 7) MUST BE FULLY TIGHTENED WHEN MACHINE IS IN OPERATION.
