PURPOSE: A five-axis cutting machine is provided to cut a workpiece at various positions and angles and to improve position accuracy by independently operating a B-axis rotating mechanism. CONSTITUTION: A five-axis cutting machine(1) comprises a spindle unit(10) and a rotating unit(50). The spindle unit is moved in X, Y, Z-axis directions and rotates a cutting tool. The rotating unit supports a workpiece cut by the cutting tool and rotates the workpiece in A and B-axis directions. And the rotating unit comprises an A-axis servo motor, a B-axis servo motor, and a rotary bracket. The rotary bracket is rotated in the B-axis direction and connects the A-axis servo motor and the B-axis servo motor.
