OPERATION
TRAVERSE SWITCH
REVERSE BUTTON
GRINDING WHEEL
MOTOR
1. Before spin grinding, lock the TRAVERSE CLAMP and check that all LOCK HANDLES are tightened.
2. Close the doors. The grinding wheel motor and spin drive will not operate with the doors open.
3. Depress the GRINDING WHEEL MOTOR SWITCH and the SPIN DRIVE MOTOR SWITCHES to ON.
NOTE: The reel should rotate in the same direction as the grinding wheel, like tandem wheels on a truck.
The actual point of contact where they meet is in opposite directions. See FIG. 30.
4. Depress the TRAVERSE SWITCH to ON and use the TRAVERSE SPEED KNOB to traverse the GRINDING
CARRIAGE until the GRINDING WHEEL is positioned below the reel.
5. Press the INFEED SWITCH to INFEED the GRINDING WHEEL until there is some light sparking on the reel.
6. Use the TRAVERSE SWITCH and TRAVERSE SPEED KNOB to traverse across the reel to find any high areas
on the reel. NOTE: If the grind starts getting too heavy, use the INFEED/DOWNFEED SWITCH to jog the
GRINDING CARRIAGE down until you can travel the full length of the reel without heavy grinding. You can
change the back-and-forth direction of the GRINDING CARRIAGE at any time by pressing the REVERSE
BUTTON. This can help speed up the time required to grind a reel that is cone-shaped (the reel is larger
on one end compared to the other). When you are able to travel the full distance of the reel without any
problems proceed with grinding the reel.
7. Infeed the GRINDING WHEEL approximately .005" at a time, allowing the grinding wheel to travel back
and forth across the reel 2 to 3 times before infeeding again.
TRAVERSE DRIVE RPM
The TRAVERSE SPEED KNOB is adjustable from approximately 5 feet
per minute [1.5 meters per minute] to 20 feet per minute [6 meters
per minute]. It is recommended to grind around 15 feet per minute
[4 meters per minute]. Grinding at a slower traverse speed, 10 feet
per minute [3 meters per minute] as an example, will give a better
finish but will extend the grind cycle time. Grind finish versus grind
cycle time is controlled by the operator.
