Q: I’m ready to perform some maintenance on my
lower head. Are there help screens available on the
machine to guide me through disassembly and then
reassembling the lower head?

touch “Regular Services,” then touch the help icon (ques-

to highlight—see Figure 1.
Once highlighted, touch the box “Lower Guide Roller,”
and the help screen will appear. From the help screen,

dielectric tank, improved eco-friendliness, and higher-quality precision at corners.

iGroove+ technology uses less wire to machine your parts in
your EDM, which can lead to signifi cant cost savings in the long
haul. In a 100mm cut, you can save nearly 30% of total wire sav-
ings. As Figure 1 shows, the wire will rotate and use a different
section of the wire when traveling from the top to the bottom.
For 0.010” wire, the standard rotation will be ±190°. There is a
clockwise and counterclockwise rotation depending on your
G42/G41 wire offset, and the rotation will move accordingly so
it climbs cuts.

Inverter pumps are incorporated in the new iGroove+ machines
to limit unnecessary electricity consumption in the fl ushing,
sending, and circulation pumps. These pumps actually con-
sume over 70% of the electricity, which is why optimizing the
pumps will have a great effect on the whole machine.
These are just a few
examples of how Sodick
iGroove+ can help your
