Planer-Thicknesser
A3-26 / A3-31 / A3-41
9.4 Surface planing
Note: Surface planing evens irregular workpiece surfaces.
The workpieces are guided over the cutterblock and only their undersides are machined.
The direction of cutterblock rotation is opposite to the feed direction of the workpiece.
9.4.1 Working position
Fig. 9-3: Work place/work position
Take up the position as shown in the opposite picture
when working with the machine
The following working techniques are absolutely forbid-
den with the planer unit:
• Down-cut planing (direction of cutterblock rotation is
the same as feed direction)
• Insertion cuts (the workpiece is not worked over its
entire length)
• Planing workpieces that are very warped
• Rabbet planing at the end of the cutterblock
9.4.3 Authorised and prohibited work techniques
Only the following working techniques are permitted
with the planer unit:
• Planing the wide side of a workpiece
• Jointing the narrow side of a workpiece
• Bevelling the narrow side of a workpiece
• Bevelling the edges of a workpiece
9.4.2 Workpiece dimensions
Length under 250 mm: only work with special devices (e.g.: wooden pushing stick)
over 1500 mm: only work with table extensions or with a second person
Width max. 260 mm / 310 mm / 410 mm (depending on the equipment)
Thickness min. 10 mm
Attention! Risk of injury!
If a workpiece is smaller than 10 mm, it may split if the depth of cut is too large (4 mm).
The finished planed workpiece must not be thinner than 6 mm!
