CNC Lathe is one of the most widely used CNC machine tools at present. It is mainly used in the inner and outer cylindrical surface of shaft parts or disc parts, inner and outer cone of arbitrary cone angle, complex revolving inner and outer surface and cylindrical and conical thread, and can be cut, drilled, reaming, reaming and boring.

NC machine tool is in accordance with the preparation of a good processing procedures, automatic processing of parts processed. We put the parts of the process route, process parameters, tool movement trajectory, displacement, cutting parameters and auxiliary functions, according to the NC machine tool instruction code and program format written into a processing list, and then the contents of this program recorded in the control medium, and then input to NC machine tool CNC device, Thereby directing the machine tool to process parts.

CNC (English name: Numerical control abbreviation: NC) technology refers to the use of digital, text and symbols composed of digital instructions to achieve one or more mechanical equipment action control technology. NC is generally used or dedicated computer to achieve digital control, so NC is also known as Computer numerical control (computerized numerical controls), referred to as CNC, foreign generally referred to as CNC, very little use of the concept of NC.
