2.4.6.1 Dielectric Fluid
Dielectric fluid is used in the machining process and is required at time of
installation and start up.
• The dielectric tank holds 200 liters.
There are three basic types of dielectric fluid, choose the type best suited
to your work
1. Mineral Fluid – provides a concentrated electrical discharge and a
removal rate 10 to 20% faster than synthetic fluids.
2. Synthetic Fluid – is recommended for machining with graphite and
when using high current settings. Synthetics have less odor and better
surface roughness than mineral fluids and promote longer filter life.
3. Intermediate Fluid – Provides performance characteristics between
those of mineral and synthetic fluids.
2.4.7 Machining Power Source
Table 2-13
lists the machining power source specifications .
Dielectric Fluids
1. Always use a highly refined oil with a minimum of PAH’s. Use an oil similar to EDM-
244 or EDM-250 to minimize any health risks.
2. Never use a dielectric fluid with a flash point under 70°C.
