PROBLEM TO BE SOLVED: To provide a multiaxis boring machine which can apply at the same time the boring machinings having many kinds of diameters to one work of a printed wiring board material from its front and rear surfaces. SOLUTION: The boring machine of the printed wiring board performs a boring machining in a printed wiring board material in order to form through-holes in the printed wiring board. An orthogonal three axes comprising horizontal axes X, Y and a vertical axis Z is set; and the boring machine has horizontal tables subjected to reciprocative driving in the X-axis direction, sliders subjected to reciprocative driving in the Y-axis direction, and a plurality of drill spindles mounted on the sliders. The plurality of sliders are provided in the up and down directions of the printed wiring board, each drill spindle is mounted on each slider, and further, the boring machinings having many kinds of diameters can be applied at the same time to one work of the printed wiring board material from its front and rear surfaces. Moreover, in order to perform the boring machinings in the area of upper and lower subtables making any boring impossible, there are provided such subtables as to slide the upper subtable thereof in the horizontal X-direction, for pressing down the printed wiring board material of the multiaxis boring machine of the printed wiring board from its front and rear surfaces to perform a presser role in the case of its boring.
