Belt grinder SM-140 27
Machining workpieces
8
1 Position the knife at the belt grinder so that the knife
blade [1] points in the direction of rotation of the grinding
belt [2] or the polishing wheel [2].
2 Align the knife blade horizontally so that it is positioned
roughly perpendicular [3] to the grinding belt.
3 Position the knife blade [4] on the grinding belt at an angle
of approx. 15 degrees [5].
4 When grinding, grind the sides of the blade alternately,
until a burr has formed over the entire area.
WARNING
Risk of injuries
The blade can cut into the grinding belt and be torn out of
your hand.
• Never grind against the cutting edge.
NOTE
Workpieces heat during grinding
An over-heated blade can anneal (loss of hardness) and stress
cracks can form in it.
• Always wet grind cutting tools.
NOTE
If the blade has become thicker as a result of frequent grinding,
the blade thickness can be reduced again by grinding the
flat sides.
