PROBLEM TO BE SOLVED: To reciprocate a pair of sliders in the mutually opposite directions, improve durability by canceling reaction forces occurring in respective sliders, and improve a machining accuracy by suppressing occurrence of noise and vibration, in a double-row working machine. SOLUTION: This double-row working machine comprises track rails 17 on a base 16, a pair of sliders 18 and 19 reciprocating on the track rails 17, respectively, turning tools 27 and 28 disposed in the sliders 18 and 19, and a driving device for reciprocating the sliders 18 and 19 in the mutually opposite directions. The driving device comprises a linear motor magnet plate 20 extending along the track rails 17, linear scales 23 and 24 disposed along the linear motor magnet plate 20, and linear motor coils 21 and 22 disposed in the sliders 18 and 19 facing to the linear motor magnet plate 20.
