Turn on the traverse drive motor switch and turn the speed
dial up to approximately 15- 20.
IMPORTANT: If the grind starts getting heavier, adjust the
grinding head down until you can travel the full length of the
reel without heavy grinding.
When grinding, infeed the wheel approximately .005” [.13 mm]
at a time. Allow the grinding wheel to travel back and forth
across the reel 2 to 3 times before infeeding. The spin
grinding is completed when full contact is made across the
entire length of the reel, the entire width of all blades and the
reel is sharp. The last passes should be a normal .005 [.13
mm] infeed grind at a slow traverse speed (approx. 8 feet per
minute [2.5 meters per minute] or slower). After the last pass
turn the grinder off.
(Note: Due to the positioning of the reel to the 1 o’clock position,
infeeding the wheel .015 inches [.38 mm] will remove .010
inches of material. )
SPIN GRINDING
After the reel has been aligned and the taper has been
adjusted for, you are now ready to spin grind the reel. Close
the front and rear guard doors. (The grinding wheel and spin
motors will not work unless the doors are closed.) Position
the spin/relief selector switch to the spin position. Turn on
the Grinding Motor and the Spin Drive Motor switch. Set the
spin speed at approximately 200 rpm (Refer to Spin Drive
RPM on pervious page). Make sure spin rotation is the same
as the grinding wheel – clockwise (CW) looking from right
end. See FIG 22.
IMPORTANT: When the reel turns in the same rotation as
the grinding wheel, the point of contact where they meet is
in opposite directions.
