Instruction Manual
Section Five
wheel periphery, lightly advance the machine Crossfeed while holding the
cutter against the toothrest with the handwheel (C). When the first
sparks appear, stop the machine Crossfeed and slowly rotate the fixture
and the Spindle Assembly to follow one spiral flute through its arc swing
to the left until the fixture stop is contacted.
3. Use the fixture tilting lever (F) to move the cutter away from the tooth­
rest for examination of the grind. If the tooth land has been contacted
uniformly, rotate the Spindle Assembly until the flute 180 degrees oppo­
site the one just ground is available, and after returning the fixture to
the center starting position, slowly release the lever until the new flute
land contacts the wheel. At this point, immediately begin to rotate the
fixture through its arc swing again, always holding the flute face firmly
against the toothrest. After the first acceptable contact of the first flute
with the wheel, the machine Crossfeed must not be moved as doing so
will destroy the true radius now established between the Pivot Point Ver­
tical Axis and the periphery of the wheel
4. After the first acceptable contact with the two flutes 180 degrees oppo­
site each other on the cutter, all additional teeth should be contacted.
At this point, infeed the fixture handwheel (A) .001 inch, sharpening all
teeth prior to the next infeed on the fixture.
5. All flutes should be round ground, finishing with a final light cut on the
primary land. If a secondary clearance appears necessary, it is produced
by further adjustment of the micrometer toothrest above the wheel center
and a consequent lowering of the Wheelhead to put the blade on center
with that of the cutter. At the end of the flutes, it will be necessary to
finish gashing by a hand operation.
V. OTHER USES OF THE RADIAL GRINDING FIXTURE
A. Forming Radii on the Grinding Wheel:
1. The diamond nib can be installed on either the Diamond Holder (B985AE),
which is in turn installed on the Stud (J) of the BA985 Fixture, or it can
be put into the B985AD Diamond Holding Arbor, which is in turn seated
into the taper of the B985H Spindle Assembly.
2. Mount the Center Gauge into the fixture Pivot Stud (49).
3. Using the fixture Upper Slide and Lower Slide, bring the diamond point
to the exact Pivot Point Vertical Axis of the fixture. Remove the Gauge
and replace the Cap.
4. Raise or lower the Wheelhead of the grinder until the diamond point is
at the wheel spindle center. The diamond point should also be centered
in the middle of the wheel width if the radius is to be centered on the
wheel periphery.
5. Using EITHER the fixture Upper Slide OR its Lower Slide, position the
diamond point beyond the Pivot Point of the fixture if a concave radius
is desired in the wheel, or position the diamond point back of the Pivot
Point to create a convex radius. Do not attempt to use both of the fixture
handwheels to reposition the diamond point relative to the Pivot Point.
6. Using fixture stops (E), set the required arc swing of the fixture.
