A tube bending machine in which a tube detecting sensor detects an amount of bending a tube during the bending process and a controlling unit performs control so that the amount of bending detected by the sensor becomes a value corresponding to the program stored in a memory beforehand; thus, the second and subsequent tubes are bent accurately and efficiently by a drive command from the memory.
