OPERATING INSTRUCTIONS
GRINDING REEL INTO A TRUE CYLINDER BY
SPIN GRINDING (CONTINUED)
5. Move the grinding wheel to the right until the
wheel has cleared the reel by approximately ¼
inch [6 mm] (if clearance to the frame allows).
Turn the Traverse speed potentiemeter to
zero. Turn on the Traverse Motor Switch, this
will activate the proximity sensors. Move
the right Traverse Travel Limit switch in until
the light on the proximity sensor illuminates.
Move the wheel to the opposite end of
the reel until the wheel clears the end of
reel by ¼ inch [6 mm] (if clearance to the
frame allows). Set the left Traverse Travel
Limit Switch. Engage the traverse belt, if not
already, and slowly turn the Traverse Speed
up. Allow the wheel to traverse from end to
end to verify the switches stop and reverse
the direction of the grinding wheel. Verify
that the grinding wheel travels fully off the
reel at each end.
CAUTION, IF THE REEL FRAME EXTENDS
BELOW THE REEL ITSELF, MAKE SURE
THE STOP IS SET SO THAT THE GRINDING
WHEEL WILL NOT RUN INTO FRAME WHEN
GRINDING. IT IS POSSIBLE THAT IN SOME
CASES THIS WILL MEAN THE GRINDING
WHEEL WILL NOT CLEAR THE END OF THE
REEL WHEN GRINDING.
6. Move grinding carriage to the high side end of
the reel and stop the carriage. Set the Grind
Selector Switch to Variable Speed Spin.
7. CLOSE THE FRONT AND REAR DOORS.
8. Turn on the spin drive motor and check to see
if reel is spinning freely and that the spin drive
and coupler is properly aligned.
9. With the spin drive running at 200 RPM, turn
on the grinding wheel motor. Verify that the
spin rotation is the same direction as the
grinding wheel, clockwise, looking at the right
end of the reel from the operators position.
Now slowly infeed the grinding wheel until it
makes light contact with the reel.
