7.1 General principles of grinding technology

If a blade has become blunt, material must be removed from its surface to restore it to its original
sharpness.

For that, the knife in question is ground to produce its cutting edge. If, in the process, a burr
appears on the blade, then the grinding process was successful and can be concluded. Now, be­fore the final sharpness is achieved, the burr must be removed in a further step. This is done with
a flap brush.

As it is not only the sharp cutting edges but also the long service lives that define a blade, the
cutting angle is another important indicator of a blade’s performance. The smaller the cutting
edge angle, the higher is the theoretical service life. In practice, however, the cutting edge breaks
off and is therefore no longer sharp when the cutting edge angle is too small.

The cutting edge angles must therefore lie between 15° and 35°. If the cutting edge angles
are less than 15°, the blade becomes so unstable that it breaks at the slightest resistance. If the
cutting edge angle is greater than 35°, the blade is extremely stable, but service life will not be as
long.

One more criterion for judging the properties of a cutting edge is the cutting edge profile.

There are three different ground profiles:

Tapered grinding Concave grindingConvex grinding

Convex ground profiles can mostly be found on cutter blades and hand knives. Tapered and
concave ground profiles are predominantly found on circular knives and blades.

In general: Adhering to the profiles and the cutting edge angles specified by the manufacturer
is required

7. Operation

There is a risk that hands, hair, and clothing may be pulled in while the
grinding machine is switched on.

This can result in serious injury.

Turning counterclockwise = less water

Push the grinding lever forward with the right
hand and rotate the knife along the cutting edge
with the left hand until burr has been formed over
the entire length of the cutting edge.

If a burr has formed over the entire blade, the
grinding unit is moved to the next locking posi­tion with the hand wheel. The knife moves in the
direction of the belt. Carry out five strokes in this
position (a stroke = grinding from the blade edge
to blade base and back again).

Then move to the next locking position and
execute five strokes again (etc.) until the entire
curvature of the knife is ground.

Then move back to position “2”. Swivel back
the belt grinding attachment including knife. The
knife can now be removed and a new one tight­ened on.

NOTICE

The locking lever must not be pressed when
moving back to locking position 2. All the
locking positions up to locking position 2 can
