geometry with precise repeatability.
Set up the Motor tower facing inward to grind using a 1A1 wheel. The motor is set level at 0° and the
Motor tower is rotated to 1.5° to 2° to create a dish shape in the end of the tool.
Set the Tool spindle collars as shown in Figure 9 so that there is enough stroke to pull the tool out of
the way of the wheel whey your indexing to the next flute but are still able engage the indexing pin.
Feed with the main table x axis feed. To grind the primary clearance angle set the wheel height to
about 0.5” below the center of the tool (~7°). Adjust to suit.
Plunge the tool unitl the index collar bottoms out then index to the next flute and repeat.
To grind the secondary clearance angle set the wheel height to about 1.25” below the center of the
tool (~20°). Adjust to suit.
primary and secondary angles are determined by the wheel height.
