利用T612镗床加工大型工件上的螺纹孔,技术难度较大,涉及到T612镗床本身的机械传动系统、电气控制系统及操作系统,并要配备特殊的刀具、工具等。利用T612镗床加工螺纹时,其主轴的回转与主轴的纵向进给量的选择,需要按一定的比例关系联系起来。其工作台纵向及横向进给量的选择与动作,不干涉主轴的回转与主轴纵向进给系统;并按一定的操作规程加工,否则会产生乱扣现象。为了保证加工螺纹的质量,必须对T612镗床进行改装。一、T612镗床机械进给系统
The use of T612 boring machine for processing large threaded holes on the workpiece, the technical difficulty is greater, involving T612 boring machine itself mechanical transmission system, electrical control system and operating system, and to be equipped with special tools, tools and so on. The use of T612 boring machine thread, the spindle rotation and the longitudinal feed of the spindle of choice, the need to be linked by a certain percentage. Its table longitudinal and horizontal feed selection and action, do not interfere with the spindle and the spindle longitudinal feed system; and according to certain operating procedures, otherwise it will produce chaos buckle phenomenon. In order to ensure the quality of the processing thread, T612 boring machine must be modified. First, T612 boring machine mechanical feeding system
