Spark Erosion Oils / EDM Oils.

The dielectric oil acts as a medium through which controlled electrical discharges occur. • The dielectric oil acts as a quenching medium to cool and solidify the gaseous EDM debris resulting from the discharge. • The dielectric oil acts as a medium used to carry away the solidified EDM debris from the discharge gap to the filter system. • The dielectric oil acts as a heat transfer medium to absorb and carry away the heat generated by the discharges from both the electrode and the work piece.

Having greater oxidation stability means that the dielectric fluid will resist degradation longer, retaining its clarity, initial viscosity, and give longer service life.

The three most important things in EDM are: Flushing, Flushing, and Flushing.


Electrical discharge machining, sometimes known as EDM, is a technique for cutting complex forms in hard materials. An electrode and a workpiece are both submerged in dielectric fluid during the operation. Electrical current runs between the workpiece and the electrode, forming tiny plasma zones that melt and remove the material in an instant. EDM electrodes come in a variety of shapes and sizes. Electrical discharge machining (EDM) is a non-traditional machining technique that is frequently employed on hard materials. The fact that EDM can mill any material, regardless of its hardness, has made it popular.


EDM is frequently used to shape or create modern technical materials that are used in harsh environments. However, there are certain disadvantages to this method. The machining effectiveness of this approach is often hampered by a lower material removal rate and high tool wear. EDM can be coupled with other standard or nonconventional manufacturing technologies to provide a more consistent and balanced machining setup. The inherent limitations of the EDM process can be solved via hybrid or mixed machining technologies. When other production methods are combined with traditional EDM, machining performance can be greatly improved.


Due to the overcut, the EDM creates a hollow slightly larger than the electrode.

Advantages: This method can cut any conductive material.

It is unaffected by the hardness of the workpiece, allowing it to be machined with ease.

It is possible to make complex die sections and complex forms with precision.

This method is devoid of burrs.

Without deforming the workpiece, thin sections can be easily machined.

Disadvantages: This machining procedure produces a lot of tool wear.

Tool wear reduces metal precision and surface finish.

EDM can only machine good conductors of electricity.
