Numerical Control Innovation Of CA6132 Common Lathe

Computer Numerical Control(CNC) machine tools'innovation was conducted by application sophisticated CNC technology theory, successful experience and low cost. The accuracy of the original machine can be restored or even improved, so that it can be adapted to industrial requirements of high-speed development by leaps and bounds. CNC machine tools'innovation was greatly developed as a new international and domestic economic growth industry. In this paper, CNC machine tools'innovation programs, technical route and so on was analyzed taking CA6132 common machine as research objects. All the contents are included as follows:The motion principle of CA6132 lathe was analyzed; It was briefly introduced the selection of numerical control system during CNC machine tools'innovation and emphatically introduces GSK-CTL Series CNC Sliding Units. According to the principles of Mechanics, Dynamics and Electronics, the main drive system of NC machine tool has been designed using AC motor speed control by variable frequency. The spindle drive system has been designed and checked. In accordance with the requirements of feeding system, the cutting force and the ball screw is calculated, and equipped with appropriate gear and feed motor. The electrical-control parts of the CA6132 lathe is designed by using P LC. The trapezoidal figures of the spindle and the servo-systems are given. The programs of the PLC are programmed. A reforming project of whole electric parts is given. The accuracy of the NC machine was restored. A reforming project of the typical parts of the servo-system is given. After CNC machine tools'innovation, the lathe has a good application effect, and achieved good processing quality and economic benefit.The research offer facility technicians in enterprises not only a scientific efficient way of realizing NC reform of traditional equipments, but also some references and lessons of other kinds of traditional facilities.
