Ensure that you turn the knives in the right
direction (see page 16) when you assemble
them in the cutter. The cutting edge must be
turned towards the chip breaker. Also check
that the cutter is facing the right direction on
the spindle. All of the planer/moulder's cutters
turn the same way as with conventional milling.
Check that the non-corrosive spring plate in
front of the moveable cutter is not at risk of be-
ing bent towards the cutter by the workpiece's
unplaned edge. Pay particular attention when
cutting workpieces of different widths.
Ensure that the cutter can rotate freely and that
the plate working as a chip barrier behind the
moveable cutter is at a distance of approx. 5 mm
from the cutter's largest cutting diameter.
HEIGHT SETTING
The side cutter's height is set by adding or remo-
ving the spacers that are supplied in the component
package on delivery.
Spacer height:
Spacers 40 mm item no. 7502-001-0038
Spacers 20 mm item no. 7502-001-0042
Spacers 10 mm item no. 7502-001-0044
Spacers 5 mm item no. 7502-001-0046
Schim set (0.1 – 2.0 mm) item no. 7502-001-0230
To remove the planing knife from the side cutters,
loosen the knife's lock screws that are recessed into
the cutters. Use a 4 mm Allen Wrench (supplied).
The height settings for tongue and grooves:
When tongues and grooves need to be moulded, it is
important that these are made opposite one another,
i.e. at the same height above the planing table.
• Remove the cutter from the spindle (see above
under the Disassembling heading).
• Decide how you want the board to look. E.g. 8
mm above the groove, 6 mm groove and 7 mm
under the groove (see image to the left).
• Assemble the molding knife and screw the
socket head screws that hold the knife properly.
• Place the cutter on the spindle completely wit-
hout spacers. Measure the distance from the top
edge of the knife down to the planer table.
If the cutter is 40 mm and the groove (6 mm in this
example) is in the middle of the knife, the height
of the knife above the groove is 17 mm. When the
cutter is pre-set, the height of the knife above the
table must be 30 mm (7 + 6 + 17 = 30 mm). If, for
example, the height of the knife above the table is
measured to 15.2 mm, the cutter must be raised
14.8 mm (0.58") (15.2 + 14.8 = 30 mm).
Take the following measures:
• Remove the cutter.
• Combine spacers to the calculated thickness
(14.8 mm (0.58") in this example) and thread
them onto the spindle.
• Place the cutter on the spindle, screw on the
lock nut and tighten properly. Check that the
cutter can rotate freely.
• Carry out the points above on the cutter with
the tongue knife, so that it is placed at the same
height above the table.
• Test-plane a small board, and check that the
tongue and groove are at the right height in
relation to one another.
Alternatively, the knife can be set arbitrarily, after
which a test bit is run. Measure the test bit and cor-
rect the knife height.
Spacers must also be placed above the cutter
so that it is xed on the spindle. Add some of
the distance rings that are not used for height
setting, so that the thickest ring lies highest and
protrudes several millimeters above the lowest
threads on the threaded bar. Then screw the
nuts on the threaded bar and tighten properly.
GRINDING
To recover the sharpness of the knife, you can grind
the at side of the knife. Thus retaining the same
prole for the pair of knives. Always grind the knives
in pairs, so that they have the same weight, other-
wise vibrations could occur in the cutter. You can
order a grinder from Logosol for sharpening planing
and molding knives (Tormek Grinder, item no. 7010-
000-1000, Jig for planing knives, item no. 7010-
000-1012).
If the prole of the knife is damaged, this should be
re-ground by a professional knife sharpener. This is
a service that is normally available locally, otherwise
contact Logosol.
