[0002] As one of the most widely used processing equipment, CNC lathes have excellent performance in precision processing of shaft parts and disc parts. They can not only efficiently cut internal and external cylindrical surfaces, internal and external conical surfaces with arbitrary taper angles, but also process complex internal and external rotating curved surfaces, as well as cylindrical and conical threads.
