Operators Manual for Drilling Machine
Bring the cutter gently into contact with the work piece and slowly start to
apply pressure on the cutter.
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 a 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 force.
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After a hole is made the cutter should be withdrawn back and both the motor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. Clean the swarf, coolant, etc, from the
machine. The cutter should be removed and cleaned.
5.5. How to use the special functions
There are many causes which can reduce magnet holding force. These can be:
insufficient work piece thickness, paint coating, rust or dirt, uneven and rough
surfaces, extensive wear of the magnets bottom surface etc.
If after turning the drills electromagnet ON, the motor starts, but then stops
when you remove your finger from the ‘ON’ button, this can be caused by the
machines safety system, which has detected insufficient magnet holding
power. You can make the motor run by continuing to hold the green Start “I”
button. To eliminate this situation, it is necessary to improve magnetic
properties of the work piece or recondition the magnetic base.
Electromagnets dual clamping system
.
Machines magnetic base is supplied with a half of normal voltage every time the
magnet is On but the motor is OFF.
This feature reduces power supply consumption and extends magnets durability.
Full power of machines magnet ( 9500 N.) is obtained a 1.5 second after the motor is
switched ON
