Vibration or rumble in the side
cutter.
1. The moulding knives are incor-
rectly mounted.
2. The moulding knives are incor-
rectly ground.
3. Defect bearing.
4. The spindle shaft has been bent
due to overloading.
5. The belt transmission is defect.
1. Demount the cutter head, and clean
and mount the knives and the chip
breakers correctly. Identical knives
should be mounted on opposite sides of
the cutter.
2. Grind the knives in pairs so that they
are identical on the opposite sides of the
cutter.
3. Replace the bearing.
4. Replace the spindle shaft.
5. Clean the belt pulleys and replace the
Poly V belt.
Rumbling or vibration in the
upper or the lower cutter.
1. The moulding knives are incor-
rectly
mounted.
2. The moulding knives or the plan-
ing
knives are incorrectly ground.
3. The bearing is defect. This can
be due to wood debris that has
accumulated on the back of the
bearing housing, which leads to
overheating.
4. The belt transmission is defect.
1. Clean the cutter and mount the knives
and the chip breakers correctly. Identical
knives should be mounted on opposite
sides of the cutter without any, or with
only slightly horizontal deviation.
2. Grind the knives in pairs so that they
are identical on opposite sides of the
cutter.
3. Clean the bearing housing and
replace the ball bearing.
4. Clean the belt pulleys and replace the
Poly V belt.
It is difficult to adjust the height
of the machine table.
1. The trapezoidal thread bars, on
which the table is suspended, are
dirty and not lubricated.
2. Faulty chain transmission.
3. The machine has been subject to
impact which has spoiled the setting
of the table.
1. Clean and lubricate the trapezoidal
thread bars with oil.
2. Make sure that the chain runs cor-
rectly on the sprockets. Clean and lubri-
cate the chain.
3. Adjust the table. (See
