由微型计算机控制的简易数控车床,价格便宜,操作方便,在改造旧设备方面获得广泛的应用。为了扩大简易数控车床的工艺范围,充分发挥其数控功能,使之能进行多刀、多工步的集中操作,在车床上都要求装置自动转位刀架。目前常用的自动转位刀架是在车床原有的四方刀架基础上改进的(《机械制造》1985.4),这种刀架可安装四把刀具,完成车外圆、切槽等工作。由于难于安装孔加工工具(钻、铰等),加之原有的刀架刚性较
Simple CNC lathes controlled by a microcomputer are cheap, easy to operate, and are widely used in retrofitting older equipment. In order to expand the range of simple CNC lathes, give full play to its numerical control functions, so that it can carry out multi-knife, multi-step operation of the step, the lathe requires automatic indexing turret. At present, the commonly used automatic indexing turret is improved on the original square turret of the lathe (“Machinery Manufacturing” 1985.4). The tool turret can be equipped with four tools to complete the car outer circle and grooving work. Because it is difficult to install hole processing tools (drilling, hinges, etc.), combined with the original rigid frame
