Machine knives with a bevelled contoured cutting
edge
Regrind the contour specified by the manufacturer with a machine
knife. First regrind the cutting edge. Use the universal angle of 27°
if no information is available from the manufacturer.
The contoured cutting edge is produced after grinding the cutting
angle. Grind three bevels for basic sharpening. The following bevel
stages are tried and tested: 17°, 13° and 9°. These grinding stages
are marked in red on the scale of the grinding device.
The grinding of bevels is similar to the V-shaped edge. However,
a burr is only formed on the cutting edge when grinding the angle
of the cutting edge.
Round the bevels in the next step on the grinding stone or on the
wet grinding belt.
Grinding the angle of the cutting edge:
1
Set the grinding angle on the grinding device to 27°.
2
Lift the workpiece off the grinding wheel with the double grind-
ing lever.
3
On/Off switch for the abrasives to position
I
(ON).
4
Set the On/Off switch for the cooling water to position
I
(ON).
5
Lower the workpiece with the double grinding lever. Move the
area to be ground back and forth over the grinding wheel with
light pressure.
NOTE
Do not stop the movement of the workpiece on the grinding
wheel.
• There is a risk that the knife will overheat and the contour will
be damaged if the workpiece remains stationary on the grin-
ding wheel.
