Cutting
- Choose a suitable lubricating fluid and fill the coolant tank.
The cooling system is an integral part of the machine and should always be used.
Warning: The cooling system works gravitationally, therefore it can be used
only when in vertical position of the drilling machine. In other positions, a
cutting paste should be used
- Check workings of cooling system. Open the coolant tank’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 the groove in pilot pin. 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.
Bring the cutter gently into contact with the work piece and slowly start to
apply pressure on the cutter.
Making a hole with an annular cutter should ideally be done in one pass.
Do not peck drill.
WARNING : When the annular 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 retracted 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.
- Select a suitable rpm speed for the machine to run at, using the table below as a guide.
Once a suitable speed has been decided upon, select that speed using the gear switch on the
side of the gearbox.
