Abstract： China is a large manufacturing country， and CNC machine tools， as important equipment for industrial production， can effectively improve the automation level of industrial production. This paper mainly discusses the fault diagnosis and maintenance strategy of the automatic tool-changing system in magazine-type machining cen‐ters， introduces the compositions of the automatic tool-changing system in detail， including the automatic toolchanging device and automatic tool-changing control system， and analyzes various common problems such as tool magazine failures， tool-changing manipulator failures and spindle tool release failures. In the terms of the failure of the automatic tool-changing control system， this paper focuses on the analysis of problems such as tool-changing point drift， tool magazine chaos and tool-changing timeout， and puts forward corresponding diagnosis and mainte‐nance strategies. It is hoped that the research in this paper can provide reference and models for related technical personnel.
