Machining Workpieces

1 Position the knife on the wet grinding belt so that the knife
edge [2] points in the direction of rotation of the wet grinding
belt [3].
2 Align the cutting edge of the knife horizontally so that it is posi-
tioned roughly perpendicular [1] to the grinding belt.
3 Position the knife blade [4] on the wet grinding belt at an angle
of approx. 15° [5]. Position the blade at approx. 20° with
a cleaver.
4 Grind the sides of the blade alternately when grinding until
a burr has formed over the entire surface.
WARNING
Risk of injury
The blade may cut into the grinding belt and be torn from the
hand.
• Never grind against the cutting edge.
NOTE
Workpieces heat during the grinding process
An over-heated cutting edge can anneal (loss of hardness) and
stress cracks can form on it.
• Always wet grind cutting tools.
NOTE
If the cutting edge has become thicker as a result of frequent grin-
ding, the cutting edge thickness can be reduced again by grinding
the flat sides.
