CNC lathe, turning center, is a high-precision, high-efficiency automation machine. Equipped with multi-station turret or power turret, machine tools have a wide range of processing technology performance, machinable linear cylindrical, slash cylinder, arc and a variety of thread, groove, worm and other complex workpiece, with linear interpolation, circular interpolation compensation functions, and in the production of complex parts to play a good economic effect.
"CNC" is an abbreviation for the English computerized numerical control (computer digital controls). NC machine tool is in accordance with the preparation of a good process program, automatic processing of parts processed. We put the parts of the processing process, process parameters, tool movement trajectory, displacement, cutting parameters (spindle number, feed, back to eat knives, etc.) as well as auxiliary functions (change knives, spindle forward, reversal, cutting fluid open, etc.), according to the NC machine tools prescribed instruction code and program format to write into the processing program form, The contents of this program are recorded on the control medium (such as punched tape, tape, disk, magnetic bubble memory), then input into the NC device of the NC machine tool to direct the machining parts.
The whole process from the analysis of the part diagram to the control medium is called the programming of NC program. The difference between NC machine tool and ordinary machine tool is that NC machine tool is to process parts automatically according to the procedure, and the ordinary machine tool should be operated by people, so we can achieve the purpose of processing different parts by changing the procedure of controlling machine action. Therefore, the numerical Control machine tool is specially suitable for processing small batch and the shape complex request high precision parts.
As the NC machine tools to process parts according to the program, programmers to prepare the program, input into the NC device to direct the work of the machine. The input of the program is controlled by the media.
