Vacuum cleaner
On the rear of all machines, there is one socket for a 3.5 mm audio plug, to be used with the va-
cuum cleaner switch box (pict.6). This adaptor will turn the vacuum cleaner on and off together
with the spindle. It comes in a black plastic housing with AC inlet and outlet for European mains
sockets and should be used with the vacuum cleaner that we supply, or i. e. with a liquid cooling
pump for aluminium routing. If you connect other devices, power rating must not exceed 1500
Watt.
The machine comes with a small 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 suction nozzle which is at the rear of
the Y axis (grey tube on top end of pict. 5). Take care that the hose can freely follow the machine
´s movement.
The chip removal may appear to be somewhat poor. This is due to the fact that the shavings are
leaving the drill bit at high speed, but not necessarily in the direction of the nozzle. Anyhow, further
encapsulation of the tool is not possible.
Mounting the spindle
Referring to picture 7, release the black lever by a 90
degree left turn so that the spindle holder clamp
opens. Carefully drop the spindle into the clamp and
push it downwards so that the distance flange (alu-
minium collar) lies firmly on the holder's top. Turn the
spindle in a direction so that the cable and the con-
nector housing do not interfere with the Z-axis' move-
ment. Fix the plug to the connector box located to the
right of the Z stepping motor (see picture 8) and
tighten the plug screw. Turn the lever to close the
holder clamp until the spindle is well tightened.
ATC: Use the short piece of air hose coming with the
spindle to connect it to the quick mount fitting on top of
the Y-axis slider, as on the left part of picture 8. There
must be the "test pin" or at least a drill bit in the chuck
when the spindle is not in use. Else, damage to the
chuck may occur.
Important: The distance flange determines the spindle
elevation over the table. It is mounted to the spindle at
the factory in a way that a drill (with ring) is 0.5 mm
over the machine table when the Z axis is completely
down. You should not change this setting. Otherwise
the mechanical position of the Z axis will be different
from the one assumed by the driver software.
Damage to the machine table may then result.
Only tools with ring (collar) 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.
