\nThis is achieved by applying our many years of experience in fine wire technology and metal plating skills.
\nWith its excellent tensile strength and ED characteristics, SP wire replaces conventional tungsten wire for precision ED wire cutting.<\/td>\n

\nImprovement of \u226510% over tungsten wire, thanks to SP wire’s high electrical conductivity.<\/li>\n
\nDue to its excellent ED stability and high tensile strength, SP provides a fine surface roughness as good or better than that of brass wire.<\/li>\n
\nWith its high tensile strength and stable ED characteristics, SP wire provides precise, fine ED cutting where the cutting width (clearance)is\u00a0\u226520% narrower and the corner radius is smaller than that with tungsten wire. Thus, the same machining accuracy can be obtained with one size larger SP wire, along with a much faster cutting speed.<\/li>\n
\nSince SP wire is flexible and has a soft and smooth surface, abrasion of the wire guides (electrified pins, guide rollers, etc.) of ED machines is far less than that with tungsten wire, reducing operating costs.<\/li>\n
\nSP wire has excellent free cast and straightness, allowing a high rate of automatic wire joining.<\/li>\n
\nSP wire provides a longer continuous length per reel: 5,000m\/reel, 10,000m\/reel and 20,000m\/reel, while that of tungsten wire is 3,000 – 5,000m\/reel. Thus, longer continuous operation and higher productivity can be achieved.<\/li>\n
\nUnlike tungsten wire, SP wire is invulnerable to surface oxidation. Remaining wire can therefore be used again easily.<\/li>\n
\nThe HOMO phenomenon, an unstable ED caused by the short-circuit, that occurs when cutting a tungsten-containing work piece (e.g., tungsten carbide) with a tungsten wore, does not occur with SP wire.<\/li>\n
\nIn addition to the excellent properties above, SP wire is far less expensive than tungsten wore, providing an excellent cost performance<\/li>\n
\nTo find the optimum cutting conditions for SP wire, first set the cutting conditions for a brass wire electrode having a diameter equal to SP wire. Then gradually increase the wire tension until the SP wire breaks. The optimum tension is that just before breakage.
\nYou may also be able to obtain SP wire cutting condition data from ED machine manufacturers.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
