    摘要: In order to form a mirror-finish surface on a workpiece (3), a machining fluid (921) obtained by blending a titanium carbide powder into an oil-based dielectric fluid which is supplied to a machining gap formed between the workpiece and a tool electrode (1, 2). The fine powder has an average particle size of about 0.5-1 .mu.m, and is supplied to the dielectric fluid in a range of about 8-50 g/l. Alternatively, the electric discharge machining fluid includes a mixture of an oil-based dielectric with a silicide powder such as TiSi.sub.2, VSi.sub.2, CrSi.sub.2, ZrSi.sub.2, TaSi.sub.2, NbSi.sub.2, MnSi.sub.2, MoSi.sub.2, FeSi.sub.2, CoSi.sub.2, WSi.sub.2, or NiSi.sub.2. The silicide powder has an average particle size of about 0.5-15 .mu.m, and is present in the dielectric fluid in a range of about 3-50 g/l.
