OPERATION
RELIEF GRIND
1. Close and latch the doors.
2. Turn the SPIN DRIVE MOTOR SWITCH to ON. NOTE: The spin drive will apply a torque load against the
FINGERS.
3. Set the RELIEF TORQUE KNOB at approximately 15. NOTE: Free turning reels may need a lower value
than 15. Stiff reels or reels with a drive train may need a higher torque than 15. Do not exceed 45 on the
RELIEF TORQUE KNOB SETTING.
4. Traverse the grinding head all the way to the left watching for proper clearance between the grinding
wheel and the reel blade. Check for proper clearance between the INDEX FINGER (after releasing from
blade at far left position) and the front side of the blade on the return trip to the HOME position. Also
verify clearance to the reel blade support spiders.
5. Stop the traverse in HOME position and check for a proper blade index (the machine will wait here until
the blade indexes). THE FINGER PROXIMITY SENSOR will send a signal when the blade has indexed to
start moving to the left. If the machine does not traverse to the left, check that the FINGER PROXIMITY
SENSOR is activated when the INDEXING FINGER is behind the reel blade.
6. Turn the GRINDING WHEEL MOTOR SWITCH to ON.
7. Turn the TRAVERSE SPEED KNOB to a proper grinding speed. Slowly infeed the grinding wheel until you
are able to grind the full length of reel evenly. You can infeed between .005" to .012" at a time. Be sure
you have ground all the blades before infeeding further.
NOTE: Traverse speed should be approximately 15 fpm. If you are removing a small amount of stock on
initial infeeds, faster traverse speeds are suggested. If you are removing a large amount of stock on later
infeeds, slower traverse speed may be required.
At this point your reel has been sharpened and shaped by the SPIN GRIND and RELIEF GRIND processes.
Simply remove the reel and SPIN GRIND the next reel.
