A cutting machine (1) prevents the size of a machine from increasing according to an increase in workpiece diameter, and at the same time improves productivity. The cutting machine (1) comprises: first and second cutting means (8a, 8b) which are installed on an external surface (52a) on one side of a guide rail means (52) and are movable on a first Y-axis guide rail (61a); and third and fourth cutting means (8c, 8d) which are installed on the other side (52b) and are 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 are disposed to face cutting blades (82a, 82b) in a suspended state. A third spindle (81c) of the third cutting means and a fourth spindle (81d) of the fourth cutting means are disposed to face cutting blades (82c, 82d) in a suspended state. The first and third spindles and the second and fourth spindles are configured to be separately movable in the X-axis direction in parallel. |
