Milling Depth Adjustment; Quick Mill-Depth Adjustment; Milling; Milling With Limit Stops - Proxxon MOF Manual

when working with certain types of wood or other materials, harmful
or explosive dusts can arise. In the interest of your own health, work
only with the suction device connected and always wear a dust pro-
tection mask in addition. Make sure you use a vacuum cleaner that
is suitable for the accruing dust.
1. Plug flexible suction hose 1 onto connection 2
2. Connect flexible suction hose 1 using rubber adapter 3 to the
vacuum cleaner hose.
When working with the vacuum cleaner, it is recommended you use
the PROXXON AS/E suction controller device

6.4. Milling depth adjustment:

Before milling, the desired milling depth must be set. The MOF
surface mill has two features for this purpose: A milling depth-
adjustment and a quick mill-depth adjustment. This is how they work:
6.4.1. Quick mill-depth adjustment (Fig. 4):
The quick mill-depth adjustment is used for preadjusting: to quickly
approach milling depths without special requirements on
precision. One uses it to move the milling height quickly into
the proximity of the desired value.
1. Clamp in the desired cutter (see chapter 6.2., „Inserting and
replacing the mill" )
2. Pull out lock-on lever 1; the spring preload presses the foot
into its lowest position.
3. Press milling-cutter head 2 into the guides against the spring
force to a position corresponding to the desired milling height
or put the cutter with foot 3 on the edge of a slab (4) (or
similar) and place milling-cutter head 2 with pulled lock lever
1 into both columns to the desired height.
4. The height is fixated when locking lever 1 is folded back.
6.4.2. Milling depth adjustment (Fig. 5):
The milling depth adjustment is used for final, precise adjustment of
the milling height. Using setscrew 1, the desired height change can
be made exact by turning it back and forth.
1. Clamp in the desired cutter (see chapter 6.2., „Inserting and
replacing the mill" )
2. Pull out locking lever 3 and place the mill cutter with foot 6 on a
stable support.
3. Carefully press the cutter against the spring force so long until
the nip of the cutter lightly touches the surface of the supporting
surface (see 1. photo, left).
4. Now turn setscrew 1 toward the bottom so long until it „sits" on
limit-stop post 4 in the milling cutter.
5. The knurl and mill cutting position is now „zeroed", so to say.
Now just let go of the mill cutter and turn the setscrew on its
thread toward the top up to the desired depth (see 2nd photo,
center). Please use scale 5 for orientation: One entire rotation of
the setscrew is equivalent to one millimeter height difference.
6. Now push foot 6 against the spring force so far in until the limit
stop on setscrew 1 „sits" (see 3rd photo, right). The mill cutter
is now set deeper than the bottom of foot 6 by the amount of the
value set in step 5. I.e., this value is also the depth of the groo-
ve that you can now mill out.
7. Fold locking lever 3 back.
The milling height has now been adjusted.

7. Milling:

General information on milling:
• When working with the surface miller, use both hands to guide
the switched-on device over the workpiece. Always work in the
counter direction during edge milling (see figure 6): The rotating
mill cutter must always run with its cutting edge against the
milling movement.
• Otherwise, there is a risk that you will end up with poor milling
work, cannot cleanly guide the device, or even that it leaps out
of your hand.
• Pay attention that the milling depth is not set too deep! Always
set the milling depth to match the type of mill cutter and the
material to be milled.
• Too deep a mill setting and too great a feed rate lead to poor
milling results and unnecessarily stresses the machine's me-
chanics! It is better to carry out several milling passes. Also,
readjust the limit stop or the cutter height often.
• Always constrain or tightly clamp the workpiece!
• For practical purposes, one should use one limit stop for each
type of milling work. There are different possibilities for this, so
only the most practical are explained here:

7.1. Milling with limit stops:

7.1.1. Milling with parallel limit stops (included in
the scope of delivery, see fig. 7a, b):
As suggested by its name, you can use the parallel limit stop to fa-
bricate grooves that are parallel to the workpiece edge, as illustrated
in fig. 7a. To do so, the supplied parallel limit stop must be mounted
and adjusted (see fig. 7b regarding this):
1. As in the illustration, push both guide bars (2) into bores 3 in
limit stop 1 and firmly tighten both headless screws (4) with
the aid of a hollow hexagon wrench.
2. Press the limit stop with both guide bars in the form as shown
in the illustration into both bores in foot 5 and push it up to the
desired distance (6).
3. Tightly clamp the limit stop with both thumbscrews (7)
You can now mill as shown in illustration 7a. Pay attention to the feed
direction: The cutter must always be able to work in the opposing
direction! (Fig. 6). If this is not the case, the limit stop must be
mounted on the opposite side.
7.1.2. Milling with the circular limit stop. (included
in the scope of delivery, see fig. 8a, b):
With the circular limit stop, you can mill out in circles or circle
segments, as shown in illustration 8a. First, the limit stop needs to
be mounted using the pin. To do so, proceed as described in the
previous point 7.1.1. „Milling with limit stops" about mounting the
parallel limit stop, but of course use the circular limit stop instead of
the parallel one:
1. As in illustration 8a, push both guide bars (2) into bores 3 in
limit stop 1 using the pin, and firmly tighten both headless
screws (4) with the aid of a hollow hexagon wrench.
2. Press limit stop 1 with both guide bars (2) in the form as
shown in the illustration into both bores in foot 5 and push it
