Frequently Asked Questions About Oils for Electric and Electronic Equipment

What Is EEO Oil Used For?

EDM oil is used as a dielectric fluid in electrical discharge machining, die-sinking, and spark erosion processes. It helps insulate the discharge gap, dissipate heat, flush away erosion debris, and maintain stable machining conditions.

What models of EDM oils are available?

Available models: LP-180, LP-200, and LP-340. LP-180 is designed for discharge currents up to 25 A, LP-200 for currents approximately from 30 to 95 A, and LP-340 for discharge currents above 95 A.

What are the key performance characteristics of dielectric oil for electrical discharge machining?

The product provides electrical insulation, low-viscosity flow, cooling, flushing, lubrication, and rust protection. These functions help remove metal particles and carbon deposits, supporting controlled spark-erosion machining.

Do you offer wholesale, bulk supply, and OEM production for EDM oil?

Yes. Ningbo MOS Chemical Co., Ltd. supports international buyers in B2B wholesale procurement, bulk supply, distributor cooperation, export services, and OEM or private label coordination through the MOSINTER GROUP industrial investment and production network.
