Sharpening of Reel Cutter (Cutting
Cylinder)
Caution
Both the reel cutter (cutting cylinder) and the
bed knife (bottom blade) are edged tools.
Handle them carefully, since they could cut
your hands and feet.
Caution
Wear gloves when touching edged tools to
avoid cutting your hands.
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.
In addition, if the reel cutter (cutting cylinder)
becomes worn and its shape conical, perform
cylindrical grinding to return it to a cylindrical
shape.
For sharpening the reel cutter (cutting
cylinder), contact your dealer or Baroness.
If the outer diameter of the reel cutter (cutting
cylinder) after sharpening is more than the
usage limit, the reel cutter (cutting cylinder) can
be sharpened.
