摘　　要：随着对电器产品的小型、轻量、高集成、高可靠性要求的提高,在印刷电路板上进行微细孔加工越来越广泛。为了加工出直径小于1mm的微细孔,我们开发出了一种能稳定运转的超高速电主轴,其最高转速可达150000r/min。本文重点介绍这种超高速微细孔钻削电主轴设计的关键技术,包括气体静压轴承的设计、内装电机的冷却与散热等。Micro-hole machining becomes more and more widely used with the demand of small size, light weight, high density and good reliability of electrical equipment. For the purpose of micro-drilling the hole less than 1 millimeter, an ultra high-speed motorized spindle is developed. It can run at the speed of 150,000 r/m. In this paper, the key technologies of the high-speed motorized spindle design and the air bearings for this spindle are introduced.
