The machine is reliably driven by a high torque
motor. Type 50/E is fitted with an electronic
speed regulator.

Operation
clamping, changing tools
Attention:
• Never press the lock button while the device
is operating.
• Depending on the collet size, bits and cutters
may have a shaft diameter of max. 3.2 mm.
• Insert the tools are far as possible when
clamping. Ensure that the shaft of the tool
does not stand out more than 30 mm from the
collet. Excessively protruding shafts can
bend easily and contribute to poor concen-
tricity.
• Do not in any case use bits and cutters with
an arbour length of more than 55 mm!
• When using collets, always make sure that
the collet chuck and the utilised tool have the
same shaft diameter! The arbour of the tool
must be seated firmly and securely in the col-
let!
• Do not work with damaged, bent or worn bits
and cutters! Make sure the tools are in per-
fect condition. Damaged or worn tools can
break and cause injuries!
• When storing the bits and cutters, make sure
they are reliably protected from damage!
• A correct and consistent speed achieves a
high grinding performance, not excessive
contact pressure!
• By tendency: Bits and cutters with smaller di-
ameters require higher speeds than those
with a larger diameter.
• Attention: You absolutely must observe the
permissible maximum speed of the bits and
cutters! The tool can break when the maxi-
mum permissible speed is exceeded. Flying
parts can cause
Attention!
Disconnect mains plug before changing tools.
1. Turn the spigot nut
1
(Fig. 2) gently while
pressing the locking knob until it engages.
2. Open the clamping jaw and change the tool.
Working with the machine
1. Push the non-reversible plug into the power
unit.
2. Switch the machine on
1
or
4
(Fig. 1) and set
the correct speed with the button
1
.
Note:
Pressing hard does not achieve good results
when grinding. Use the correct speed and
maintain it.
small tools pins = high speed
big tools pins
= low speed
3. Fig. 3 shows two typical methods for holding
MICROMOT 50. When working, ensure that
the tool is held firmly in order to guide the ro-
tating application tool in a controlled manner
without thereby blocking the ventillation slots.
4. If the unit overheats, switch it off and allow it
to cool for a few minutes.
The electronic speed regulation works only with
non-stabilized power units (e. g. all PROXXON
power units). If connected to a battery, the unit
will only run at max. speed.
Disposal:
Please do not dispose of the device in domestic
waste! The device contains valuable sub-
stances that can be recycled. If you have any
questions about this, please contact your local
waste management enterprise or other corre-
sponding municipal facilities.
