1.2.2 Insert the power cord into power socket (10), then connect
AC220V/110V power supply. Make sure the machine is grounded.
1.2.3 As for outputs of the high-frequency power, connect the red
alligator clip (positive pole) to the work piece, the other line
(negative pole) to the spindle by electrode chuck.
1.3 Connection of water pipe
Connect the water outlet of external water pump with universal joint
and set the universal joint at the machining parts, then align the
processing point. Put the water inlet with filter into the tank, ensure
that the water pump submerged in the liquid to avoid the pump
damaging.
2. Processing Steps:
2.1 Adjust position and height of the spindle, make sure the electrode
and broken items are coaxial to avoid damaging the work piece.
2.2 After adjusting the position, turn on the power switch (8), press the
water pump button (3) press high-frequency button (2) after water
flowing. Press servo switch (4) to the bottom position. Turn Servo
Control (5) clockwise to the right of central line until Down
Indicators light up, the spindle begins to decline. When electrode
approaches the work piece, up and down indicators flash alternately,
the processing begins. At this moment, you can adjust the discharge
gap by turning the servo adjusting knob (5) or adjust the current by
pressing the stepper current buttons(6).
3. Usage of Reset Key
When work head reaches the default depth, spindle would start the
trip switch and fallback automatically. At the same time, power box
would alarm. Then you can press the reset button(15) to stop the
alarm and get the work head back to work.
4. Usage of Vibration Button
During processing, turn the servo switch (4) to the upper position to
start vibration motor in the work head. The vibration motor would
oscillate the electrode which would double the processing efficiency.
When processing high precision holes, the vibration should be closed
as oscillation may reduce accuracy.
5. Shutdown Procedures
When the processing is unstable or processing speed is too fast or the
spark is visible from the bottom , it is proved that the drill or tap has
been smashed. Shutdown procedures.
5.1 Press the high-frequency button (2)
5.2 Turn Servo Control (5) counterclockwise until up indicator lights on
and spindle begins to rise , leaving the electrode away from the
work piece. Turning off the spindle servo and water pump.
5.3 Turn off main power switch(8)
V. Attentions
1. The external water pump is a precision part, please be careful when using.
1.1 The working liquid must be clean water or special cutting liquid. The
inlet pipe should install the filter.
1.2 At the first time, you should wait for about 3-5 seconds, after there is
no air in the pipe, the water will flow out.
1.3 When the temperature is below zero, if you do not use the machine,
please guarantee no water in pump to avoid damaging.
2. In case the working liquid is kerosene (the flashing point is above 70℃),
PLEASE DO NOT USE THE PUMP (the pump will be broken when it
meets kerosene). The level of working liquid should be more than 20mm
higher than the work piece. Otherwise, fires will occur when the oil level
is too low.
