中走丝电火花线切割机的新发展

New development of medium-speed wire cut electrical discharge machine

中走丝线切割机并非是它的走丝速度介于高速走丝与低速走丝之间,而是能均匀地实现无条纹切割和多次切割,其加工质量优于普通高速走丝线切割机。介绍了中走丝线切割机多次切割的工艺效果,论述了现代制造业需要清洁生产,重视产品防护包装技术。指出采用无油脂的水溶性工作液及环保过滤水箱是中走丝线切割机的最新发展;采用交流伺服机驱动和全闭环控制及分段补偿技术将是中走丝线切割机未来的发展趋势。

Instead of being characterized by wire speed, features of MS-WEDM （medium- speed wire electrical discharge machine） are cutting without stripes and multiple cutting, which leads to a better quality than HS-WEDM （high-speed wire electrical discharge machine）. Process results of MS-WEDM multiple cutting was introduced. While demands of cleaning production in modern manufacturing industry and the importance of protective package technology was discussed, the latest development of MS-WEDM were oil-free and water-soluble working fluid and environmental protection filter tank. AC servo driving, closed-loop control technology and segmented compensation technology are the development trends of MS-WEDM.
