    • PROBLEM TO BE SOLVED: To provide a deep hole processing device capable of processing a highly accurate large diameter deep hole, by using a general purpose machine tool, without requiring processing of a pilot hole. SOLUTION: The deep hole processing device forms a hole by rotatably moving a main spindle 17 attached with a tool 8 in a portal machine toward a workpiece, and includes a bush 9 having a hole for guiding the rotational movement of the tool 8 and a bush holding part 11 arranged on a cross rail movable on a column in the portal finishing machine and holding the bush 9 at a predetermined distance to a main spindle head 1 attached with the main spindle 17, and is characterized in that a position to the workpiece of the bush 9 and pressure of pushing the bush 9 against the workpiece, can be controlled by the movement of the cross rail.

    • PROBLEM TO BE SOLVED: To provide a method for drilling a printed board, which can improve the machined quality (the positional accuracy, roundness, etc. of drilled holes) and the working efficiency by suppressing the run-out of the tip end of a drill, and further to provide a machine for machining the printed board. SOLUTION: The overhung length of a drill 3 protruded from a spindle 6 when the drill 3 has been held by the spindle 6 is preliminarily determined according to the kinds or the using conditions of the drill 3. When one drill 3 is selected from a plurality of drills so as to correspond to the shape of the hole to be drilled of the printed board, and is held by the spindle 6, the drill 3 is held such that the selected drill 3 protrudes from the spindle 6 by the overhung length corresponding to the selected drill 3. After that, the printed board is drilled by controlling the spindle 6 so as to move with respect to the printed board, and also by rotationally driving the selected drill 3 by the spindle 6.
