模具作为制造行业的基础性装备,对于实现产品的大规模、批量化、流水线生产有着不可替代的作用。随着社会发展的需要以及科学技术的发展,模具制造引入了新型设备,实现了模具的精准化、规范化制造。其中电火花加工技术作为一种先进的加工工艺,以其独有的精密细微、仿形逼真等众多优点成为了目前模具制造的主流方法。文章简单介绍了几种目前较为常见的电火花加工技术,并对其工作流程进行了分析说明。 Mold as the basic equipment manufacturing industry, for the realization of large-scale products, batch, assembly line has an irreplaceable role. With the needs of social development and the development of science and technology, mold manufacturing has introduced new equipment and realized the precision mold and standard manufacturing. EDM which as an advanced processing technology, with its unique precision subtle, realistic and so many advantages of copying has become the mainstream of the current mold manufacturing methods. The article briefly introduces several of the more common EDM technology, and its work flow analysis.
