Ring Fence TAPOA 1639 and KOALA 1637
The optionally available ring fences are used for accident-free milling of curved workpieces by means of a clamp-
ing template. It is suitable for spindle diameters of 30, 35, 40 and 45 mm and for tool diameters up to 160 mm.
The ring fence can be quickly attached to the milling table and is easy to adjust. The transparent protective cover
always allows an optimal view to the cutter head.
A clamping template must always be used for shaping the workpiece during curve milling.
Only work with the ring fence when the extraction system is connected.

Adjust the thrust ring (
1
) so that the diameter printed
on the inlet side corresponds closest to the diameter
of the tool. To do this, the thrust ring may need to be
rotated.
Example:
With a tool diameter of 140 mm,
the thrust ring must be installed as shown
in
•
The height of the thrust ring (
1
) can be adjusted
using the two clamping levers (
9
) at the rear of
the fence parallel to the table top. It can be
mounted either above or below the tool.
•
The height of the workpiece hold-down and the contact guard (
2
) are adjusted to the required level with
the two clamping levers (
10
) on the rear side of the fence.
•
The feed strip (
3
) can be swivelled away by loosening the clamping lever (
4
) if necessary. Further, it can
also be mounted on the other side (with a different spindle rotation direction).
•
The tangential point (
T
) is marked on the thrust ring. This mark is used to measure the maximum cutting
depth. The adjustment is made by loosening the two clamping levers (
5
) and turning the adjusting wheel (
7
).
•
The two brushes ensure that milling chips are wiped off and optimally extracted during work.
•
After the adjustment work, always make sure that all screws and levers are tightened again.
•
Before milling, check that the milling tool does not touch the fence.
•
If the workpiece hold-down is worn, it must be replaced.
Avoid climb milling, as this considerably increases the risk of accidents! When switching to the
direction of rotation "climb milling" the signal light (R) lights up (see section
Remark:
In contrast to the
“
TAPOA 1639
”
(SI-TEC Art. No. 2246) with only 1 thrust ring, the type
“
KOALA 1637
”
(SI-TEC Art. No. 2245) has 2 thrust rings but is almost identical in design and operation.
