7.8 Grinding hand knives on the wet-grinding belt
There is a risk that hands, hair, and clothing may be pulled in while the
grinding machine is switched on.
Never hold the cutting edge against the running direction of the
wet-grinding belt. Serious injury may result!
Polishing releases grinding particles that could enter the eyes. Wear
safety glasses.
CAUTION
Lay the hand knife flat onto the wet-grinding belt
(7-7/1).
The cutting edge should run an angle to the
grinding belt, not perpendicular. Press the knife
onto the grinding belt with your free hand. The
stronger the pressure, the more convex the grind
will be.
Pull both sides of the hand knife over the grinding
belt alternately until a small burr is created over
the entire cutting edge length.
Deburr and polish the knife on the finned brush
(7-8/1). This will help the hand knife retain its final
sharpness.
Gently remove the burr using moderate pres-
sure. To do so, the hand knife is guided approx.
6 – 10 times over the polishing wheel, alternating
between left and right (left – right – left – right –
left).
