摘　　要：基于高硅铝合金无缸套发动机缸体缸孔材料的磨削特点,开发了一种数控双主轴珩磨机床。该机床采用二工位双主轴的珩磨加工布局,由以下模块组成:主轴箱、立柱、立柱下滑台、工件装夹工作台等;采用主轴珩磨双进给机构及珩磨头油石双涨机构;采用基于运动控制卡的全闭环控制系统,系统硬件平台采用工控机和通用工业运动控制卡,运用基于差压式珩磨在线气动测量系统,实现加工量的闭环控制;软件平台采用Windows系统,采用VC++开发工具编制珩磨工艺加工程序。Based on high-silicon aluminum alloy no-cylinder-liner engine block bore materials grinding characteristics,a dualspindle CNC honing machine tool was developed. In the machine tool,two-position two-spindle honing layout was used,it consisted of the following modules: spindle box,column,column glide,workpiece clamping table and so on. Spindle honing dual feed mechanism and honing oilstone double feed body were adopted. A closed loop control system based on motion control card was used. The system hardware platform was IPC and general industrial motion control card,based on the pneumatic differential pressure measuring honing online system,processing volume closed-loop control was achieved. The software platform was Windows system,VC + + development tool was used to program specialized processing procedures for the honing process.
