The numerical control turning processing

Turning processing is one of the most basic processing method in machining, it is on the lathe workpiece rotation movement and the movement of the tool is used to machining, thus turning processing is the most widely used processing method in mechanical processing, lathe 40 ﹪ of the total number of cutting machine tools. 1. The classification of the numerical control lathe (1). According to the numerical control system function points: (1) full functional numerical control lathe; According to the main shaft configuration form points: (1) bedroom CNC lathe; According to the numerical control system to control the number of shaft points: (1) two axis control CNC lathe; (2) four axis control CNC lathe 2. The numerical control turning processing the main object of the numerical control lathe is mainly used for machining shaft, disk revolving body parts, such as by performing numerical control program, can automatically complete the outer cylinder, forming surface, thread and end surface machining, and the car can hold, drilling, reaming, reaming, etc. According to the characteristics of the nc machining, CNC lathe is the most suitable for cutting has the following requirements and characteristics of the revolving body parts (1). 3 of axially symmetrical parts with special thread. The numerical control turning processing technology in the analysis of the numerical control machining with CNC machine process problems as the main research object, on the basis of the principle of technology of mechanical manufacturing, combining with the machining characteristic of nc machine tools, integrated use of various knowledge to solve process problems in nc machining. Process is reasonable or not, to the programming, the machining accuracy of machine tool processing efficiency, parts have very important influence.
