2.3 Cutting
- Select the right speed for the tool you intend to use (see the speeds chart in this
manual
– paragraph IV no.1).
Cooling and lubricant fluid commercially available in concentrated are recommended using
for cooling twist drill and annular cutter.
It’s allowed to use of emulsions formed from a mixture of water and drilling oil.
Do not use clean water as the liquid cooling and lubricant.
The cooling system is an integral part of the machine and should always be used. (see point
2.7)
Warning: The cooling system can only be used when drilling machine is in
vertical position. In other positions additional external source of cooling should be
used, for example: a coolant bottle with a long nozzle.
-
Check working of cooling system. Open coolant reservoir’s tap and apply pressure on
the pilot by turning spokes counter clockwise. As the pilot starts to sink into the cutter cooling
liquid should start to run down cutters inner wall. If there is no liquid flowing down check if the
tap is fully opened. It may take a few seconds for cooling liquid to fill the whole system.
-
Turn the motor on.
Making a hole with a milling cutter should ideally be done in one pass. It makes the
cutter work better and easier to eject the slug after the hole is completed. If you experience
slugs getting stuck inside a cutter after hole is complete try to reduce pressure on the cutter
or use different coolant. Do not allow excessive swarf build up around the cutter and arbor.
WARNING: when the milling cutter goes through the material the
slug can be pushed out often with considerable strength.
Pay attention to avoid injury.
-
After a hole is made the cutter should be withdrawn back and both the motor and the
electromagnet should be switched OFF.
-
When work with the machine is finished the power cord should be disconnected from
the power source, the machine should be cleaned up from swarf, coolant, etc and the cutter
should be removed and cleaned.
Please keep all recommendation.
