Sodick Wire EDM’s are precision machine tools and should be treated as such.
Preventative maintenance will eliminate unnecessary problems, downtime, and
aggravation and should be performed on a regular basis religiously. Sodick Wire EDM’s
had a reputation in the industry to run longer and in dirtier conditions between
maintenance intervals than their competitors. This does not mean maintenance is not as
important and should be put off until you start having problems with the machine. "Don’t
fix it if it ain’t broke" theory doesn’t apply here. Ideally, the machine should be located in
an environment where the air is clean (not right next to a grinder) and temperature
doesn’t fluctuate more than several degrees (not located in direct sunlight or by air duct,
etc.)
NOTE: To remove the EDM residue that accumulates on the machine and on the
workpieces, cleaners that contain phosphoric acid, hydrogen chloride or equivalent are
needed. Toilet bowl cleaners SNO-BOL and ALLOUT work well. AC-500 is a cleaner
that works well and is not as harsh as toilet bowl cleaners (1-800-842-3919). These
cleaners should be rinsed off within several minutes with water and will decrease the life
of the DI resin if too much of it gets into the system.

In the “DSPLY” “MENTE” screen (figure 12-1), there is a bar graph that will turn red
when the item is due for service. It can be reset after an item has been serviced, returning
the bar graph to 100% and green. The setting for “MAX TIME” is adjustable, and should
be set to a value. The value “TIME” displays the machining hours that the item has.
