CNC lathes and turning centers are high-precision and high-efficiency automatic machine tools. The machine tool is equipped with multi-station turret or power turret, which has a wide range of machining performance, and can process linear cylinders, oblique cylinders, arcs, threads, grooves, worms and other complex workpieces. It has a variety of compensation functions of linear interpolation and circular interpolation, and has played a good economic effect in the mass production of complex parts.
"CNC" is the abbreviation of English Computerized Numerical Control. The NC machine tool automatically processes the machined parts according to the pre-programmed processing program. We write down the processing route, process parameters, tool path, displacement, cutting parameters (spindle revolutions, feed rate, back-feed rate, etc. ) and auxiliary functions (tool change, spindle forward and reverse rotation, cutting fluid switch, etc.). ) according to the instruction code and program format specified by CNC machine tools, a processing program sheet is compiled, and then the contents of this program sheet are recorded on control media (such as punched paper tape and magnetic tape).
