摘　　要：The central region model (CRM) cyclotron is the experimental platform for the key technology study of a high intensity beam cyclotron.In this paper we introduce the spiral inflector and central region designed for the CRM cyclotron,including the physical design,the numerical control machining and the installation precision control techniques.The shape of electrodes is complex,and machining with a strict tolerance must be done by a numerical control machine tool with the number of its axles no less than 4.The electrodes of central region were finished by using 3-axle machine tools.The size of gaps between the ground and Dee tip is very important,a special device was made to guarantee the installation precision,and the error of gaps was controlled within±0.05mm.中心区模型试验装置是进行强流回旋加速器关键技术研究的实验平台.本文介绍了为该试验装置所设计的偏转板和中心区,包括物理设计的考虑、数控加工技术及安装精度的控制技术.由于电磁场的相互作用粒子在偏转板中的的轨迹为螺旋线,其电极形状复杂,加工采用四轴联动以上的数控机床完成.为满足束流动力学的需要,中心区的电极结构比较复杂而且不规则,表面光洁度要求高,另外尺寸和安装位置精度要求严格.中心区曲面电极结构由三轴联动加工中心加工完成,中心区地电极与高频D板头部的电极间隙非常重要,在安装过程中,制作了专用的"电极间隙通止规"控制电极间隙精度在±0.05mm.
