In microelectrodischarge machining (micro-EDM), dielectric plays an important role during machining operation. EcoSpark 105. is a blended aliphatic hydrocarbon fluid of high purity based on mineral oils for use in EDM machines. The EDM process is mainly used for making dies, moulds, parts of aerospace, automotive industry and surgical components etc. 6. One of the most widely used non-traditional processes. Effects of EDM on Metal Surfaces […] Not only will the use of up-to-date EDM oil enhance your profits, it will also boost morale of the EDM department and not be offensive to visiting customers. Fluids not designed for use in an EDM system may be dangerous to the operator, the workplace, and could damage your EDM equipment. Irritant contact dermatitis from dielectric fluid has not been reported previously. Application. Wire EDM (AP/EXC series) Colorless and odorless Good water/oil separation and stable oxidation enables little necessity of oil changes. The machining characteristics are greatly influenced by the nature of dielectric used during micro-EDM machining. Requires dielectric fluid, which creates a path for each discharge as fluid becomes ionized in the gap. Vacmul EDM is very pure fluid designed for maximum machine productivity and operator comfort when used in electrical-discharge machining, also called spark-erosion machining. Spark Erosion Dielectric Fluid is a light viscosity hydrocarbon, of low aromatic content and odour. Use the appropriate fluid - in sinker EDM machines use dielectric fluid. Sometimes also referred to as spark machining, spark eroding, burning, die sinking, wire burning or wire erosion. EDM Oil / Dielectric Fluid Tips.

This paper reviews the research trends in EDM process by using water and powder mixed dielectric as dielectric fluid. Role of Tool Electrode and Dielectric Fluids in EDM 6. Fluids not designed for use in an EDM system may be dangerous to the operator, the workplace, and could damage your EDM equipment. The dielectric fluids generally used are transformer on silicon oil, white spirit (or kerosene) or paraffin. Recent health and safety concerns have accelerated this overdue interest. When used dielectric is sucked, a vacuum pressure is created; and hence, fresh dielectric from the surroundings in the machining chamber automatically comes within the inter-electrode gap. Sounds simple enough, but many shops use a cheap mineral oil in an effort to save money. 10.1 DIELECTRIC – OIL Di-Spark, The eDM Machining Company. It serves several purposes: It acts as a semiconductor between the energized wire and the workpiece to maintain stable and controlled conditions for ionization in the spark gap. The dielectric fluid, or coolant, used in the wire electrical discharge machining (EDM) process, is deionized water.
