摘要:

阐述了高低双速走丝电火花线切割机的设计概念、实现方式和特点。通过一次高速走丝大能量切割、多次单向低速走丝切割并加大电极丝张力等措施,与高速走丝多次切割(中走丝)方式进行了对比试验。结果表明高低双速走丝的切割精度、腰鼓形均比中走丝切割方式有明显改善,而表面粗糙度值则略有提高。

关键词: 高低双速走丝, 多次切割, 精度, 腰鼓形, 表面粗糙度

Abstract:

The design concept, realizing way and characteristics of high-low traveling speed WEDM were expounded and the advantages of high speed WEDM and low speed WEDM were integrated.By adopting high traveling speed of wire-electrode with high energy discharge in the first cutting and one-way low traveling speed of wire-electrode while increasing tension force in the latter multi-cutting of high-low traveling speed WEDM, tests were done to compare with “multi-cutting of HSWEDM”. The results of tests show the cutting accuracy and drum type of high-low traveling speed WEDM are improved obviously, however, surface roughness is a little worse, compared with the “multi-cutting of high speed WEDM”.

Key words: high-low traveling speed WEDM(wire-cut electrical discharge machining), multi-cutting, accuracy, drum type, surface roughness
