3.5 Cutting straight shouldered tenons
Also with this type of tenon, it is important
to check that the pointer (no. 13 - Fig. 9)
points to the value "0" at the indicator scale
(no. 14) at the segment for tilting.
Never tilt the milling unit with the
protection curtain closed!
To set the tenon dimensions and for subse-
quent machining, proceed as follows:
1. Perform the steps 1 to 5 described in
section 3.4.
2. By turning the hand wheel (no. 11 - Fig.
8) at the edge of dimension "X1" (see
Fig. 6) pursuant to the scale (no. 12) at
the 6).
3. By turning the hand wheel (no. 21 - Fig.
12), set the horizontal path of the mil-
ling unit in such a way that the position
indicator shows the width of the tenon +
the shoulder dimension "X1".
Example: For a desired tenon width of
10 cm and a shoulder dimension of 3
cm, set the pointer to a dimension of 13
cm.
4. Perform the steps 8 to 10 described in
section 3.4.
3.6 Cutting angled tenons
Important: Before machining,
the workpiece must be cut
diagonally in accordance with
the desired angle!
To set the tenon dimensions and for subse-
quent machining, proceed as follows:
1. Loosen the handle lever (no. 15 - Fig. 9)
and tilt the milling unit until the pointer
(no. 13) points to the finished angle on
the scale (no. 14). Then, re-tighten the
handle lever.
Never tilt the milling unit with the
protection curtain closed!
2. Set the operating mode selection switch
(no. 7 - Fig. 5) to position "1" and fold
open the lid of the machine housing.
3. To set the tenon dimensions "t" and
"Z2" and the distance "Z1" (see Fig. 6)
between lower edge of tenon and lower
edge of workpiece, follow the steps de-
scribed in paragraph 2 to 6 of section
3.4.
4. Set the horizontal travel path of the mil-
ling unit by means of the hand wheels
(no. 11 - Fig. 8) and (no. milling unit 12).
First, use the hand wheel (no. 11 - Fig.
8) to set the face-grinding dimension "0"
or the shoulder dimension "X1" as de-
scribed under 3.5.2. Now, using the
handwheel (no. 21 - Fig. 12) set the ho-
rizontal path as described in 3.5.3
5. Press the pushbutton "Z-" to return the
milling unit to the lower end position.
Then, set the operating mode selection
switch (no. 7 - Fig. 5) to position "3" and
close the lid of the machine housing.
6. Lay the marked workpiece against the
contact edge of the workpiece support
und insert it into the slide-in opening un-
til the mark is aligned with the 0 position
(Fig. 14), which correspond to the line
projection of the laser. Then, fix the
workpiece with the screw clamp (no. 26
- Fig. 14).
7. Press the Start pushbutton (no. 8 - Fig.
5). The protection curtain closes. The
milling head automatically follows the
preset tenon contour, including face-
grinding and producing a shoulder. Si-
multaneously, the tenon is chamfered.
After completion of the cycle, the milling
motor returns to home position and is
switched off. The protection curtain
opens automatically.
3.7 Cutting vertical tenons
The machine design also allows for cutting
vertical tenons (see Fig. 17). Note that this
type of machining is only suitable for maxi-
