Zusammenfassung:PROBLEM TO BE SOLVED: To provide a multi-spindle machining device achieving versatility while ensuring the minimum interval of boring positions. SOLUTION: Each main spindle unit 3 is structured to be divided into a main spindle portion 4 and a motor portion 5, and each motor portion 5 is structured by a brushless motor (a direct-current motor). As each main spindle unit 3 is thereby independent, and a boring interval is easily changed, and versatility is high as compared with a multi-spindle head using a gear train. Compared with a conventional multi-spindle machining device 1 using an alternating current motor, the main shaft unit 3 is greatly downsized, and the minimum boring interval is ensured.
