在快速走丝线切割机床上,要显著改善加工表面粗糙度,主要的方法是采用多次切割。但是由于丝速产生的钼丝剧烈振动,仿照慢速走丝所用的多次切割工艺无法实现。因此,必须根据快速走丝的特点,在第二次切割时设法减少振动的影响。当钼丝张力调整合适时,采用电极丝退离电解抛光法,不用限位器和恒张力机构,也能取得令人满意的结果。一、工作液和脉冲电源根据二次切割时电极丝需要退离的具体
In the fast thread cutting machine, to significantly improve the processing of surface roughness, the main method is to use multiple cuts. However, due to the rapid vibration of molybdenum wire generated by the wire speed, modeled on the slow cutting wire used in multiple cutting process can not be achieved. Therefore, we must try to reduce the influence of vibration during the second cutting according to the characteristics of quick wire-taking. When the molybdenum wire tension adjustment is appropriate, the use of wire electrode electrolytic polishing method, without stopper and constant tension mechanism, but also to obtain satisfactory results. First, the working fluid and pulse power according to the second cut when the need for wire electrode retreat specific
