7.1.7 Grinding linear cutter knives (convex cutting edge)
Grinding, polishing and deburring releases abrasive particles that can
enter the eyes.
Wear protective glasses.
CAUTION
Switch on the grinding machine (7-22/1) and
coolant unit (7-22/2).
With linear cutter knives, each segment is ground
separately (1 segment = corner to corner).
Using the grinding lever (7-23/1), move the knife
evenly over the grinding wheel with moderate
force.
Grind until a small burr forms on the cutting edge.
Now reduce the grinding angle on the hand wheel
(7-24/1) by 5° and grind until the first chamfer is
only approx. 3 mm wide.
Reduce the grinding angle by 5° again and grind
until the second chamfer is approx. 3 mm wide.
Repeat the process until approx. 5° is reached.
