PURPOSE:To enable a workpiece to be three-dimensionally moved with respect to a tool, by securing a workpiece mounting bed, which turnably supports a rotatable workpiece bed fixing a workpiece around an axial line crossing at a right angle with the rotary axial line of said workpiece bed, onto a table able to reciprocate in three axes directions. CONSTITUTION:A table 3 can move reciprocating in directions of X, Y and Z axes. A workpiece mounting bed 4 is secured onto the table 3. The workpiece mounting bed 4 has a workpiece bed 5 able to exchange a workpiece to be mounted and removed. The workpiece bed 5 is able to turn about a vertical center axial line 6. The workpiece bed 5 is turnably supported about a rotary axial line 7 crossing at a right angle with the center axial line 6 further in parallel with a short lengthwise direction of the table 3, for instance, lateral direction of the drawing. Accordingly, the workpiece on the workpiece bed 5 enables its three-dimensional shaped machining to be performed by a tool. |
