Milling of circles (e.g. to create an annular groove)
is easy with the circle attachment, and even the
milling of slots parallel to edges presents no dif-
ficulty. We have also provided a suitable stop for
this purpose!
The adjustable depth control aids determination
of the working depth, so that the same slot depth
can even be guaranteed when machining different
workpieces!
Please note that the power tool used must have
an option for clamping with the Ø 20 mm Proxxon
collar (e.g. the IBS/E industrial drill grinder illus-
trated here). Only these devices can be clamped
with adequate safety and reliability!

Using the milling device (Fig. 2):
Caution:
1. Clamp an appropriate tool 1 in the milling
device 2. Please note: Always clamp the tool
as short as possible.
2. Insert the spindle neck of the milling device
into the opening 3 as illustrated. Please ensure
that the device does not collide with the guide
columns.
3. Tighten the two knurled screws 4 evenly to
clamp the milling tool safely and firmly.
Adjusting the milling depth (Fig. 3)
The initial position should be adjusted prior to
commencing any work. This is realised after
inserting the milling device, clamping it and
securing the workpiece.
1. Following clamping, press the electric tool
downwards far enough for the milling tool to
just touch the surface of the workpiece.
2. Tighten the clamping screws 1.
3. Screw the knurled nut 2 down to the milling
motor bracket 3.

Note:
4. Release the clamping screws 1 again. The
upper tool position is now defined.
5. The working depth for the milling tool can now
be adjusted with the knurled nut 2. Caution:
One revolution is equivalent to 1 mm milling
depth!
6. If necessary work gradually in several working
steps and partial feeds until the ultimate
desired milling depth is reached!
Adjusting the drilling depth (Fig. 3)
1. Clamp the drill in the electric tool.
2. Following clamping of the electric tool in the
milling motor bracket, press the tool down-
wards far enough for the drill to just touch the
surface of the workpiece.
3. Tighten the clamping screws 1 (Fig. 3).
4. Adjust the nut 4 to suit the desired drilling
depth. The drilling depth is the dimension from
the lower edge of the threaded rod to the
upper edge of the nut.
5. Loosen the clamping screws 1. You are now
ready to drill.
Milling straight slots with the aid of the paral-
lel stop (Fig. 4)
1. Secure the workpiece firmly to the workbench
(e.g. with screw clamps).
2. Set the milling depth as previously described.
3. Set the parallel stop 1 at the desired distance.
Loosen the knurled screws 2 for this purpose
and position the guides 3 as desired in the
base of the device 4.
4. Switch on the milling motor and set the appro-
priate speed.
5. Guide the router attachment evenly and at a
suitable speed along an appropriate edge of
the workpiece.
Caution: Only half the stop is guiding towards the
end of the milling procedure. Exercise particular
care here!
Milling edges (Fig. 5)
The feed should always be contrary to the cutting
direction of the milling tool when milling contours
(i.e. counter rotation (Fig. 5).
Proceed in a similar manner to slotting where only
the edge of, for example, a plate is to be cham-
