CNC lathe is one of the more widely used CNC machine tools. It is mainly used for the cutting of the inner and outer cylindrical surfaces of shaft parts or disc parts, the inner and outer conical surfaces of arbitrary taper angles, the internal and external curved surfaces of complex rotation, cylindrical and conical threads, and can be grooving, drilling, reaming, reaming and boring.
CNC machine tools are automatically processed on the processed parts according to the pre-programmed processing program. We compile the processing process route, process parameters, motion trajectory, displacement, cutting parameters and auxiliary functions of the parts into a processing program list in accordance with the instruction code and program format specified by the CNC machine tool, and then record the content in the program sheet on the control medium, and then input it into the CNC device of the CNC machine tool, so as to direct the machine tool to process the parts. In July 2023, the 25th Institute of the Second Academy of Aerospace Science and Industry successfully developed a high-precision optical automatic centering CNC lathe integrating optical detection, fine-tuning and processing, and passed the engineering pilot application verification, and the technical level reached the leading position in China.
