9.1.7 Grinding cutter knives
Grinding, polishing and deburring releases abrasive particles that can
enter the eyes.
Wear protective glasses.
CAUTION
Switch on the grinding machine (9-15/1) and cool-
ant unit (9-15/2).
Move the grinding unit from adjustment position
to grinding position “1”.
To do so, press the locking lever (9-16/1) with your
thumb and turn the hand wheel (9-16/2) coun-
terclockwise towards the grinding belt with your
remaining four fingers until grinding position “1”
is reached (9-16/3).
Release the locking lever (9-16/1).
With sickle-shaped cutter knives, each cutting
segment is ground separately (1 segment =
corner to corner).
Using the grinding lever (9-17/1), press the knife
against the grinding belt (9-17/2) with moderate
force and move it evenly over the grinding belt.
Grind until a small burr forms on the cutting edge.
