摘要
随着航空航天、医药、汽车及电子工业的迅速发展,精密设备及微结构的制造需求逐年增加,微小孔(d≤1mm)作为微结构中的常见难加工特征,其制造技术是限制相关领域装备发展的关键所在,因此,微小孔制造一直是机械加工行业的研究热点和难点,诸多学者从多种维度进行了相关研究,形成了丰硕的研究成果。由于微小孔钻削技术现阶段仍然是微小孔制造的核心工艺,而刀具性能则是保证微小孔钻削的核心要素,因此总结了近年来微钻刀具制造领域的重要技术进展,并从微钻刀具的材料选择、几何角度设计、制造工艺方法等角度展开叙述,介绍了最新的微钻刀具材料研究进展、解释了微钻刀具几何角度的设计方法,总结对比了国内外最新的微钻刀具制造技术,包括磨削、电火花磨削、高频激光加工技术等。由于PCD微钻具有优异的切削性能和极大的技术潜力,还重点介绍了PCD微钻制造技术及最新研究成果,并针对不同材料、工况下的微小孔钻削加工工艺参数进行了总结。
With the fast-paced development of aerospace,medicine,automobile and electronic industry,the demand of precision equipment and microstructure increases steeply.The common difficult to cut feature of micro holes(d≤1mm)in microstructure is the key to promote the development of related fields.Therefore,the micro holes manufacturing had always been a hotspot and challenge in the machining industry.Many researchers have conducted relevant research from multiple perspectives and generated fruitful research results.As micro holes drilling technology and tool performance is still the core of micro holes manufacturing at this stage,,this paper summarizes the important technical progress in the field of micro drilling tool manufacturing in recent years.This article focus on the selection of micro drilling tool materials,geometric angle design of micro drilling tools,manufacturing process methods of micro drilling tools,etc.This paper also summarizes the processing parameters of microporous drilling under different materials and working conditions,which can be used as the basis for the selection of processing parameters.
