3.3. Operating
Plug the milling unit power cord into the socket
1
(Fig. 6), and connect the cord
2
to
the power source. Then, set the power switch
3
to the position
‘I’ and use the knob
4
to change the travel speed of the carriage to the least possible value. Select
“right”
direction of the travel using the switch
5
, and start the motor with the button
6
.
Fig. 6.

After
the
travel
is
started,
set
a
speed
that
will
ensure
sufficient
milling performance
and
prevent
the
overload
of
the motor and excessive wear of the cutting inserts. Good
effects are achieved with a speed at which the overload lamp
7
will not flash.
The plate must be at all times pressed by two track clamps positioned as close to
the current position of the carriage as possible. When the carriage approaches the
track clamp, relocate the track clamp to the other side of the carriage.
Establish bevels in several passes and not exceed 4
mm (0.16’’) of the milling
head penetration
d
(Fig. 1) in a single pass. When the carriage reaches the plate
end, either toggle the switch
5
to the opposite travel direction or first stop the carriage
with the button
8
and then readjust the bevel depth or angle.
In an emergency, use the emergency switch
9
to shut off the power. To
restart
the
operation in such a case,
remove
the cause of the shutdown, unlock the
emergency switch, and start the machine using the button
6
.
If the speed is too high for the bevel width and depth that are set, the machine will
stop and start cyclically. In such a case, decrease the travel speed or milling head
penetration in the workpiece.
