Lathe equipment introduction "CNC lathe is one of the more widely used CNC machine tools at present. It is mainly used for cutting and processing internal and external cylindrical surface of shaft parts or disk parts, internal and external conical surface of any taper angle, complex rotary internal and external surfaces and cylindrical and conical threads, etc. It can also carry out grooving, drilling, reaming, reaming and boring, etc. CNC machine tools are in accordance with the pre-programmed processing program, automatic processing of the parts to be processed. We put the parts of the processing process route, process parameters, tool trajectory, displacement, cutting parameters and auxiliary functions, in accordance with the CNC machine tool provisions of the command code and program format written into a processing program list, and then the contents of this program list recorded on the control medium, and then input to the CNC machine tool CNC device, so as to command the machine tool to process the parts."
