RELIEF GRINDING CONTINUED
Close and latch doors.
Turn the Spin Drive motor on.
NOTE:
The spin drive will apply torque load against
the fingers.
Set the Relief Torque Potentiometer 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 potentiometer setting.
Traverse all the way to the left watching for proper
clearance between the grinding wheel and the 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.
Stop the traverse in home position and check for a
proper blade index. The traverse drive control is
factory set with a two second dwell time before it
reverses the carriage travel. This is to allow time for
the reel to rotate and the index finger to catch the
next blade. If necessary the dwell time can be
adjusted (refer to Control Board Potentiometer
Adjustments section on Page 24 in the Assembly and
Service Manual).
Turn on the Spin Drive Motor (should already be on)
and the Grinding Wheel Motor.
Turn on the traverse speed pot to proper grinding
speed. Slowly infeed grinding wheel until you are able
to grind the full length of reel evenly. You can infeed
between .010" to .020" [.25-.50 mm] 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.
