The flagship medium wire cutting machine is a landmark product of medium wire cutting machine. The machine tool is equipped with Japanese THK high-precision linear guide, high-precision ball screw, WinXP OR WES7 operating system, imported AC servo drive system, two-way reciprocating constant tension wire tensioning mechanism, and four link mechanism for taper. The guide wheel, screw barrel and bearing have passed the vibration and dynamic balance tests. The machining effect can reach 0.8 stably μ m. The stable value of machining accuracy is ≤ 0.008mm, the stable machining efficiency is 120-150mm2/min, the maximum machining efficiency is 300mm2/min, and the maximum machining taper is 30 °. It is mainly used in motor, instrument, light industry, automobile, light industry, household appliances, mold and other industries. It is applicable to the processing and cutting of precision parts with small volume and complex shapes, as well as the processing and cutting of complex surfaces such as equal cone, variable cone and up and down abnormity.
