Abstract
A spindle head having a spindle is moved along a Y-axis relative to the fixed bed of a printed-circuit board drilling machine, a work table is moved along an X-axis perpendicular to the Y-axis, and a tool magazine is moved along a .beta.-axis parallel to the Y-axis relative to the work table to bring the respective axes of the spindle and desired one of a plurality of tool posts arranged in rows and columns in the tool magazine into alignment with the axis of a pressing member included in a tool pressing mechanism fixedly held on the fixed bed under a tool changing position. The tool pressing mechanism is actuated to transfer a tool from the tool post to a chuck attached to the spindle or from the chuck to the tool post. The work table is lightweight and hence can be rapidly moved. The tool changing mechanism needs only simple control for a tool changing operation.
