Logosol PH260 - Height Adjustment

17
- Carry out the points described above on the cutter head that
holds the tongue knives, so that it comes at the same height
above the machine table.
- Run a short test board through the machine, and make sure
that the tongue and groove appear at the correct height in
relation to each other.
Alternatively, the knives can be set haphazardly, after which a
short test board is run through the machine. Measure the test
board and adjust the height of the knives.
Spacers must also be placed over the cutter head so that
the cutter head can be xed on the spindle. Use some of
the spacers that are not utilized for the height adjustment,
placing the thickest spacer on top so that it extends a couple
of millimetres over the lowest threads on the threaded bar.
Then, screw on the nut on the threaded bar and tighten it
rmly.
Grinding
To get the knives sharp again, you can regrind the at side of the
knives. This way the knife pair keeps the same prole. Always
regrind the knives in pairs, so that they keep the same weight,
otherwise vibrations can appear in the cutter head. You can
order a grinding machine from Logosol for regrinding planing
and moulding knives (Tormek grinder ref. no. 7010-000-1000,
jig for moulding knives ref. no. 7010-001-1012).
If the knives’ prole is damaged, the regrinding should be carried
out by a professional.
Height adjustment
The height of the side cutters is set by adding or removing
the spacers you nd in the parts box that comes with the
machine.
Spacer sizes:
Spacer, 40 mm ref. nr. 7502-001-0038
Spacer, 20 mm ref. nr. 7502-001-0042
Spacer, 10 mm ref. nr. 7502-001-0044
Spacer, 5 mm ref. nr. 7502-001-0046
Set of spacers (0.1 – 2.0 mm) ref. nr. 7502-001-0230
When straight planing, you just have to ensure that the knives
are processing the full side of the work piece.
To remove the planing knives from the side cutters, you loosen
the knives’ lock screws, which are recessed in the cutter heads.
Use a 4 mm Allen key (supplied).
Height adjustment for tongue and groove: When you are going
to produce tongue and groove it is important that the tongue and
groove are facing each other, i.e. they are at the same height
measured from the machine table.
- Remove the cutter head from the spindle (see above under
the heading Removing the side cutters).
- Decide on the size and location of tongue and groove, e.g. a
6 mm wide groove, 8 mm from the upper side of the board,
and 7 mm from the lower side of the board (see picture to
the left).
- Mount the moulding knives and rmly tighten the Allen screws
holding the knives.
- Ret the cutter head on the spindle without using spacers.
- Measure the distance between the upper edge of the knife
and the machine table.
If the knife is 40 mm and the groove (6 mm in this example) is
centred on the knife edge, the knife’s height above the groove
is 17 mm. When the cutter is set up the knife’s height above
the machine table should be 30 mm (7 + 6 + 17 = 30 mm). If
the knife’s height above the table is 15.2 mm, for instance,
the cutter should be raised 14.8 mm (15.2 + 14.8 = 30 mm).
Proceed as follows:
- Remove the cutter head.
- Take the amount of spacers needed for the calculated height
(14.8 in this example) and place them on the spindle.
- Fit the cutter head on the spindle, screw on the lock nut and
tighten it rmly. Make sure that the cutter head can rotate
freely.
