It is difficult to process the screws of Φ508 mm casing tubes with high quality,which are caused by three aspects： tube diameter,manufacturing tube technology and screw parameter inspection.Then the paper studies the influential mechanism of tube diameter,manufacturing tube technology and screw inspection on the quality of screw processing,and systematically analyzes the reasons why it is difficult to control the screws processing quality of Φ508 mm casing tubes.Finally,one set of technologies about tube manufacturing,screw processing and inspection of Φ508 mm casing tubes are optimized according to the characteristics of present manufacturing tube techniques and screw processing technology.
