Cutting (continued)
- 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. Move magnet switch to “DEMAG” position
for one or two seconds to reduce residual magnetism.
- 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.
