当今社会,先进生产技术飞速发展,产品不断更新,新材料应用也越来越广泛,随之而来的加工难度也越来越高,我在工作中就遇到了这种情况。在一次外协加工时遇到一批零件,纯钨材质,需要在上面加工四个平行小孔,孔径1.3毫米,孔深30毫米。既是稀有材料又是小孔和深孔,加工难度大。拿到零件图,看到材料为金属钨时就难住了,纯钨又硬又脆,熔点又高,无法用一般机械加工方法加工该孔,为此经过多方交流讨论和实验,最后确定采用闸流管脉冲电
Today’s society, the rapid development of advanced production technology, product updates, new material applications are also more and more widespread, followed by the processing more and more difficult, I encountered in the work of this situation. In an outsourcing process encountered a group of parts, pure tungsten material, the need to process the above four parallel holes, aperture 1.3 mm, hole depth 30 mm. Both rare materials and holes and deep holes, processing difficult. Get the parts figure, see the material is hard to live when the metal tungsten, pure tungsten and hard and brittle, high melting point, can not be machined with the general machining of the hole, for which after many parties to discuss and experiment, and finally determine the use of Thyristor pulse electricity
