Suction House, adjustable height
On
HPMU
, you can lock the
Suction House
in any
height; still, it is allowed to move upwards.
This function is useful in order to:
1.
Adapt to different material thicknesses.
2.
Allow false air input in order to reduce suction
force.
Procedure:
1.
Loosen lock screw (a).
2.
Adjust suction house to desired height.
Spindle RPM limitations
Running 8 mm bits at a high RPM rate can generate vibrations and excessive wear.
Using
Milling Bits
with extended length at high RPM can also be dangerous.
Therefore, using long
Milling Bits
is subject to an automatic RPM reduction.
If you are using short 8 mm bit, these must be limited manually to 40.000 RPM.
In general, 6 mm bits are preferable in materials up to 20–25 mm thickness.
12.10.3. Safety issues
Unattended Operation
Depending upon the material processed, milling introduces some risks.
It is a good rule to keep an eye on a milling job being executed.
Pay special attention to:
• Do not leave the machine running if the vacuum cleaner can be over-filled. This might cause
damage, or in worst case a fire if the suction house is clogged.
• Ensure the filter inside the vacuum cleaner is cleaned regulary.
• Be aware the risk of suction tube clogging.
• Be aware the risk of suction house clogging.
• Milling MDF or other fine dust materials requires extra attention in order to keep the vacuum
cleaner filter clean.
