This dielectric oil for electrical discharge machining is a mineral-based lubricant, suitable for spark erosion machining of steel workpieces or other molds using graphite electrodes or copper electrodes. The dataset includes major raw and auxiliary materials from the production process; infrastructure such as energy use, production equipment, and factory construction is not within the system boundary of the dataset. The life cycle inventory is compiled from data derived from multiple sources. The production activities of the dielectric oil involve batching, mixing, stirring, filtering, and purifying processes.
