摘要
随着产品高度集成小型化,切削尺寸逐渐减小,微切削技术受到了国内外越来越多的关注。本文从印制电路板、钛合金、铝合金、镍基合金、淬硬钢等难加工材料出发,综述了各种难加工材料微细钻铣加工存在的难题。从切削力、刀具磨损、表面粗糙度、微细毛刺、表面加工硬化等方面进行讨论,介绍了针对难加工材料微细钻铣削常用的涂层种类,归纳了影响涂层微钻铣刀切削质量的相关因素,包括材料粘附性、切削力波动、磨粒磨损等。总结了各种难加工材料适用的微细钻铣刀具涂层,并提出一些改善涂层微钻铣刀具切削质量的方法及建议。综合经济性、材料加工适应性原则,开发出最佳涂层微细钻铣刀具,不断地提高微切削的质量,对微小零部件、微电子产品的发展具有重要意义。
With the high integration and miniaturization of products,the cutting size is gradually reduced and the micro-machining technology has aroused more and more attention of scholars both at home and abroad.Based on the difficult-to-machine materials such as printed circuit boards,titanium alloys,aluminum alloys,nickel-based alloys and hardened steels,the problems of micro-drilling and micro-milling are reviewed.From the aspects of cutting force,tool wear,surface roughness,fine burr,surface work hardening,etc.,the types of coatings commonly used for micro-drilling and micromilling are introduced.The factors affecting the cutting quality of coated micro-tools are summarized including material adhesion,cutting force fluctuation,abrasive wear,etc.The coatings of micro-drills and micro-milling cutters suitable for various difficult-to-machine materials are suggested.Some methods for improving the micro-machining quality of coated micro-drills and micro-milling cutters are proposed.Based on the principles of economy and material processing adaptability,developing suitable coated micro-tools and improving the micro-machining quality are of great significance for micro-components and micro-electronic products.
