精密不锈钢丝很难拉拔，拉拔时不可避免地使用高粘度润滑剂和/或加入极压添加剂。这反过来又需要强力的非环保脱脂剂，而且，当包括氯添加剂在内的润滑剂最终被焚烧时，会释放二恶英。在这项研究中，提出了一种解决问题的方法，即利用超声波拉丝，以便能够使用低粘度润滑剂，尤其是无氯润滑剂。我们可以通过对拉伸模具施加径向或弱轴向超声振动来实现这一目标。

Precision stainless steel wires are difficult to draw, when they are drawn, the use of lubricants with high viscosity and/or the inclusion of extreme-pressure additives is unavoidable. This, in turn, requires strong and non-environmentally friendly degreasing agents and moreover, emits dioxin when lubricants including chlorine additives are finally incinerated. In this study, a solution for the problems, whereby ultrasonic wire drawing is utilized, has been proposed in an effort to enable the use of low viscosity and in particular, chlorine-free lubricants. We could achieve this goal by applying either radial or weak axial ultrasonic vibration to the drawing die.
