<p>A 3-dimensional (3D) variable-axis machine is disclosed, which includes a frame (10) spaced from a base to be disposed at an upper surface of a workpiece, forward and backward pivoting frames (20) having an arch shape connected to the frame, leftward and rightward pivoting frames (30) having an arch shape and a relatively less height than the forward and backward pivoting frames (20) to be connected across the forward and backward pivoting frames (20), and a spindle (50) vertically inserted in an intersectional portion between the forward and backward and the leftward and rightward pivoting frames (20, 30) to be pivoted corresponding to movements of the both pivoting frames (20, 30). The spindle (50) is connected to a sliding member (40), and the sliding member (40) is connected to a lower surface of the forward and backward pivoting frames (20) and an upper surface of the leftward and rightward pivoting frames (30) in a sliding manner.</p> |
