异形化学纤维及其产品是发展化纤工业的主要品种。而异形孔喷丝板是纺制异形纤维的一项关键部件,异形孔喷丝板的研制成功与否和质量情况直接影响异形纤维及其产品的试制。同时这项工作对于发展我国精密电火花加工技术也会有很大的促进作用。本文主要是总结一年多来采用电火花线切割工艺来制造异形孔喷丝板方面的技术和经验。 Profiled chemical fiber and its products are the main varieties of chemical fiber industry. The special-shaped hole spinneret spinning fiber is a key component of the special-shaped hole spinneret, the success or failure of the quality and shape of a direct impact on the production of shaped fiber and its products trial. At the same time this work for the development of China’s precision EDM technology will also have a significant role in promoting. This article summarizes the technology and experience in using wire-cut electrical discharge (EDM) to manufacture spinnerets that have been shaped for more than a year.
