Connect the one 25 pole and two 15 pole cables coming from the control unit. They cannot be
interchanged. The red and blue outlets are reserved for later extensions and are actually not
beeing used.
The Cinch socket takes the cable of the included vacuum cleaner switch box. This box is desi-
gned for astandard 230 Vsupply and amaximum power of 500 W. This box may also power
e. aliquid pump for cooling when routing aluminium.
2.1.1 (ATC) Compressed air connection
The machine requires compressed air of at least 5bar to open and close the spindle chuck.
compressor is not included with the machine. At the left rear of the machine there is an
valve. Connect the spiral air hose´s free end to that valve. The other end of the hose has a
standard connector for compressed air outlets.
Use the short piece of air hose coming with the spindle to connect it to the fitting on top of
Y-axis slider.
2.2 Mounting the spindle
Release the holder clamp by a90 degree left turn of the lever on its right side. Carefully drop
the spindle into the clamp and push it downwards so that the distance flange lies firmly on
holder's top. Turn the spindle in adirection that permits to fix the cable in the small black
clamp on top of the Z-axis block. The cable and the connector housing must not be bent by
must not interfere with the Z-axis' movement. Fix the plug to the connector box located to
right of the Zstepping motor and tighten the plug screw. Turn the lever to close the holder
clamp until the spindle is well tightened.
Important: The distance flange determines the spindle elevation over the table. It is mounted
to the spindle at the factory in away that adrill (with ring) is 0.5 mm over the machine table
when the Zaxis is completely down. You should not change this setting. Otherwise the Zaxis
mecanical position will be different from the one assumed by the driver software. Damag to
machine table may then result. See the "Z Axis Definition" in the Appendix.
Only tools with ring should be used. The distance from the top edge of the ring to the tool
tip is 21 mm. The spindle distance flange was factory set with respect to that 21 mm active
tool length.
(ATC): There must be the "test pin" or at least adrill bit in the chuck when the spindle is not
in use. Else, damage to the chuck may occur.
2.3 Vacuum cleaner
The machine comes with asmall bench top vacuum cleaner. After connecting it to the switch
box, put it on the table at the rear of the machine and fix the hose to the exhaust valve which
at the left front (MTC) or at the rear (ATC) of the Yaxis. Take care that the hose can freely
follow the machine´s movement.
The swarf removal may appear to be somewhat poor. This is due to the fact that the
are leaving the drill bit at high speed, but not necessarily in the direction of the valve.
2.4 (ATC) Tool receptacles
On the front end of the machine there is abar with 16 tool receptacles. They are numbered
from 0to 16. Number 0always takes the test pin. The drill and router bits go into the
15 round pieces. These can move vertically and also have asmall rubber ring inside which
keeps the bit ring in position. The positions of the receptacles are known to the software by
entries to the configuration file.
In front of the tool position No. 0there is the drill break detector. The driver software operates
the machine in away that after each drill was used it is checked in this sensor. The LED on top
of it lights up when the drill is found to be good.
2.5 (MTC) Tool change
To open the spindle chuck, press down the knob on top of the spindle and turn it left. Remove
the tool and insert anew one. Press and turn right the knob to close the chuck. To gain better
access to the tool, You may lift the spindle but it is not recommended to pull it off entirely.
