PROBLEM TO BE SOLVED: To prevent the generation of any adverse influence on working quality due to vibration transmission between working parts at the time of carrying out precise working or vibration working by one working part, and to shorten a waiting time between the working parts. SOLUTION: This machine tool is provided with two working parts 1 and 2 such as two-axial lathe, and at the time of carrying precise working or vibration working, the other working part is allowed to wait when a specific point comes. The specific point is decided according to a working limit code 23. The working part 1 for limiting working and the working part 2 whose working is limited are decided. The working side whose working is limited continues its working as long as any limit request is not issued. The working to be limited is not limited to one. Also, the points for allowing the working part to wait is not limited to one.
