Sharpening of Reel Cutter (Cutting
Cylinder)
The sharpening of the reel cutter (cutting
cylinder) consists in maintaining its roundness
and creating a relief (second edge face).
This work should be performed if the
sharpness cannot be restored, even after back
lapping, or if the relief (second edge face) has
worn away.
Sharpen the reel cutter (cutting cylinder) when
the sharpness cannot be restored, even after
back lapping, or when the relief (second edge
face) has worn away, there is full contact or
back lapping takes too much time.

unless you have a grinding machine.
Caution
Both the reel cutter (cutting cylinder) and the
bed knife (bottom blade) are edged tools.
