REEL SPIRAL (CONTINUED)
5. Loosen the two (2) vertical adjustment lock
handles on the carriage base. Use the vertical
adjustment handwheel to raise the grinding head up
approximately seven (7) turns so the reel blade can
rest on the reel guide finger. It will be necessary to
infeed the grinding wheel to accomplish this. See FIG.
72.
6. Adjust the position of the grind wheel to achieve the
desired relief angle. (The average recommended
manufacturer's angle is 20 to 40 degrees. Check
with the cutting unit manual as to the exact angle
required.) By looking down the reel from the
operator's position you can see the reel blade and
its relative position to the grinding wheel. By raising
the grinding wheel you will decrease the relief angle
and conversely by lowering the grinding wheel you
will increase the relief angle. When the relief angle
is correct, traverse the grinding wheel assembly to
the right side of the reel. Retighten the two vertical
adjustment (2) lock handles.
7. Adjust the index finger positioning by rotating the
back stop knob on the bottom forward of the grinding
head. This position must allow approximately 1/16"
(1.5 mm) free play of the index finger when the blade
is resting on the high point of the relief finger.
See FIG. 71-73. The Index Finger position must be set
to stop the reel blade and allow traversing to the left
without the blade hitting the side of the relief finger.
8. Turn the traverse speed potentiometer to zero, then
turn the traverse drive motor on. Using the speed
potentiometer to slowly move and stop the grinding
wheel left until the reel blade is on the fixed relief
finger.
9. Adjust the grinding head forward until there is
minimal clearance between the reel blade and the
grinding wheel.
OPERATING INSTRUCTIONS
THE WHEEL TRAVELS OFF THE BLADE, BUT
THE BLADE STILL RESTS ON THE FIXED FINGER
THE MOVEABLE INDEXING FINGER SPRINGS
FORWARD TO BE IN FRONT OF THE BLADE.
THE MOVEABLE INDEXING FINGER WILL BE IN FRONT
OF THE BLADE WHEN TRAVELING LEFT TO RIGHT.
THE MOVEABLE INDEXING FINGER WILL CATCH
THE NEXT BLADE AS THE CURRENT BLACE COMES
OFF THE FIXED FINGER ON THE RIGHT SIDE.
