Step 1: After clamping the blade in the head of the fixture and with the fixture set at 45º, place a 30 micron disc on the head of the machine. While holding the fixture in the full stop position set the Hira-To® speed to 1 and turn the machine on so the disc is spinning clockwise. Then lay your blade on the 30 micron disc.

Step 2: After touching the blade to the disc, rotate the head of the fixture around to see where the blade has been scratched by the pad.

Step 3: If the scratch on the blade is farther from the edge, this means your angle is too steep. Adjust your angle to 40º and test your blade again. If the scratch on the blade is riding the edge, your angle is too flat. Adjust your angle to 50º and test your blade again.
