-
MOUNT RECESS TOOL IN THE TURRET OF THE
SCREW MACHINE.
-
SET TOOL FOR RIGHT OR LEFT HAND
OPERATION BY LOOSENING CAM SCREW (2) AND ROTATING BODY (1) UNTIL CAM
SCREW (2) AND ROTATING BODY (1) UNTIL CAM SCREW (2) IS IN THE CAM
GROOVE IN FINE ADJUSTING SLEEVE (5) THAT MOVES THE BODY (1) IN THE
DIRECTION DESIRED. IT IS IMPORTANT IN ALL CASES THAT THE
PRESSURE OF THE CUTTING ACTION IS DOWNWARD (NOT UPWARD) WHETHER THE
SPINDLE IS RUNNING FORWARD OR BACKWARD. THIS WILL PREVENT THE
CUTTING TOOL FROM SPRINGING AND DIGGING INTO THE WORK.
-
LOOSEN CLAMP SCREW (12) AND ROTATE
HEAD OF TOOL SO THAT THE CUTTING TOOL (8) IS AS CLOSE AS POSSIBLE TO
I.D. OF HOLE TO BE RECESSED. THEN TIGHTEN CLAMP SCREW (12).
-
WITH CAM FOLLOWER AT THE START OF THE
RECESSING LOBE ADJUST STOP ADJUSTING SCREW (3) AND CUTTING TOOL (8)
LENGTHWISE SO THAT WHEN STOP ADJUSTING SCREW (3) CONTACTS THE SPINDLE
CAP OF THE SCREW MACHINE (OR THE STOP RING ON THE #2 B&S MACHINE)
THE CUTTING TOOL (8) WILL BE AT THE CORRECT DISTANCE INTO THE HOLE AT
WHICH THE PART IS TO BE RECESSED. TIGHTEN LOCK NUT (4).
-
THE FORWARD MOTION OF THE TURRET WILL
NOW MOVE THE CUTTING TOOL SIDEWAYS INTO THE WORK AT A 1:1 RATIO.
THE CORRECT DEPTH OF CUT (1/8 MAX) IS SET BY COUNTER ADJUSTMENT OF THE
TWO SLEEVE ADJUSTING SCREWS (6). THIS ADJUSTMENT CAN BE SEEN BY
WATCHING THE ZERO LINE OF THE FINE ADJUSTING SLEEVE. BE SURE THE
CLAMP SCREW IS TIGHT BEFORE MAKING FINAL ADJUSTMENTS.
-
THE TOOL CAN ALSO BE USED FOR O.D.
GROOVING BY SETTING THE CUTTING TOOL CLOSE TO THE O.D. OF THE PART AND
SETTING THE TOOL SO THAT IT MOVES TOWARDS CENTER.
-
TO DISASSEMBLE THE ENTIRE TOOL REMOVE
THE ASSEMBLING SCREW (11). WHEN REASSEMBLING THE TOOL BE SURE
THAT THIS SCREW IS TIGHT SO THAT THE STROKE OF THE TOOL IS NOT
CHANGED.
-
WHEN THE R&L RECESSING TOOL IS SET
UP ON TURRET LATHES THE SHANK OF THE TOOL IS HELD IN THE TURRET, WHEN
USED ON THE MULTI-SPINDLE AUTOMATICS THE TOOL IS HELD IN A HOLDER MADE
FOR THE TOOL SLIDE. ON BOTH MACHINES PROVISIONS WILL HAVE TO BE
MADE ON THE CROSS SLIDE FOR MOUNTING A STOP AGAINST WHICH STOP
ADJUSTING SCREW WILL STRIKE. AS IN ABOVE DIAGRAM.
