Please bear in mind that the vibration and noise emission
can deviate from the values given in these instructions,
depending on the conditions of use of the tool. Poorly main-
tained tools, inappropriate working methods, different work
pieces, too high a feed or unsuitable work pieces or materials
or unsuitable bits and cutters (here: saw blade) can signifi-
cantly increase the vibration load and noise emission across
the entire work period.
To more accurately estimate the actual vibration and noise
load, also take the times into consideration where the device
is switched off, or is running but is not actually in use. This
can clearly reduce the vibration and noise load across the
entire work period.
Warning:
• Ensure regular and proper maintenance of your tool
• Stop operation of the tool immediately if excessive vibra-
tion occurs!
• Unsuitable bits and cutters can cause excessive vibration
and noises. Only use suitable bits and cutters!
• Take breaks if necessary when working with the device!
Assembly of the milling machine
- Attach the compound-type table 1 (Fig. 2) to the base 2
with the 4 x M4 Allen screws supplied.
- The milling machine must now be fastened to a stable
work surface with 4 screws 3.
Operation
Installation of the collet chucks
Disconnect the mains plug before changing tools. Tighten-
ing the union nut without a suitable shank inserted, dam-
ages the collet chuck.
1. Block the spindle with a spanner and release union
nut 1 (Fig. 3).
2. Insert the required collet chuck 2 using suitable inserting
tool 3.
3. Block milling spindle and re-tighten union nut.
All inserting tools must be tightened with as little protrusion
as possible. Excessively protruding shanks vibrate and
cause poor milling results.
Setting the spindle speed
The spindle speed can be adjusted continuously by means
of the electronic control.
In general:
Large milling tool diameter = low speed
Small milling tool diameter = high speed
The correct spindle speeds are indicated on the table on the
front of the milling machine.

Note:
Milling
Always wear protective goggles when milling. Always
observe the enclosed safety regulations.
1. Fasten the work piece with the clamps supplied or in a
vice.
2. Switch on milling machine at switch 1 (Fig. 4).
3. Adjust the required milling depth using handwheel 2.
1 turn = 1 mm feed
4. Tighten clamp screw 3.
5. Work with a suitable feed and with a suitable milling
depth. The feed must always be against the cutting direc-
tion of the milling tool (Fig. 5).
6. Release clamp screw 3 before readjusting the cutting
depth (Fig. 4).
The MF 70 MICRO Milling Machine is designed for precise,
fine machining. Therefore, adopt suitable milling depth and
feed rate. Otherwise, poor quality milling results are to be
expected. Furthermore, thermal damage may be caused to
the electric motor due to continuous overloading.
Adjustment of scale on compound-type
table:
The scale rings on the handwheels are moveable and can
thus be set to zero without traversing the table. In addition to
the scale rings, the KT 70 micro-compound-type table is
equipped with a moveable scale for adjustment in the
X direction 19 (Fig. 1).
Adjustment of guide play
Disconnect the mains plug before making any adjustments.
All 3 axes of the milling machine are equipped with an
adjustable dovetail guide. If, after a time, a guide is found to
have too much or too little play, the play can be reset via the
adjusting screws (Fig. 6). In order to adjust the play in the X
direction, first release the nut 1 (Fig. 6). Then set the play
using the set screws 2. Lock by re-tightening the
nut 1. Adjustment of play for the other two axes is performed
analogously.
Do not over-tighten the set screws as, otherwise, the guide
may be damaged. Evenly tighten all the set screws.
Maintenance, cleaning and care
Disconnect the mains plug prior to every adjustment, mainte-
nance measure or repair!
