PROBLEM TO BE SOLVED: To enhance productivity while preventing increase in the device area due to large diameter of a workpiece.SOLUTION: A cutting device (1) includes first and second cutting means (8a, 8b) provided on one outside surface (52a) of guide-rail means (52) and movable on a first Y axis guide-rail (61a), and third and fourth cutting means (8c, 8d) provided on the other outside surface (52b) and movable on a second Y axis guide-rail. A first spindle (81a) of the first cutting means and a second spindle (81b) of the second cutting means are disposed in suspension state while facing the cutting blades (82a, 82b) each other, and a third spindle (81c) of the third cutting means and a fourth spindle (81d) of the fourth cutting means are disposed in suspension state while facing the cutting blades (82c, 82d) each other. The first and third spindles, and the second and fourth spindles are constituted movably in parallel in the X axis direction. |
