Face Grind and Depth/Back Grind Adjustments
It is important to know that face grind and depth/back grind adjustments are related.
Adjusting one WILL affect the other. By design, face grind increases as tooth depth
increases. A light face grind at the tip of the tooth becomes heavier as the grinding wheel
drops to the lowest point in the grinding process. (This is more noticeable on tall tooth
profiles than on short tooth profiles.) Adjusting face grind after adjusting depth grind will
change the amount of grind on the back side of the tooth.
As you operate the sharpener, the cam will rotate causing the index arm to contact a tooth
and push it to a position under the grinding wheel. The cam will also raise and lower the
grinder for the indexing process.
CAUTION!
When indexing the blade during setup, adjust or
manually lift the Sharpener head up to prevent the CBN
wheel from dragging along the blade. Failure to do so will
result in damage to the CBN wheel surface and cause pre-
mature wheel wear.
See Figure 3-1.
The index arm can be adjusted to leave the tooth closer to or further from
the grinding wheel so the tooth face is ground lighter or heavier.
