Conventionally, in order to process the hole, a hole having a shape suitable for the shape of the three-dimensional pipe is provided in the drill machine.

Particularly, in the drilling operation described above, since the holes to be formed in the three-dimensional pipe are not formed in only one direction, the three-dimensional pipe must be rotated. When the shape of the part to be processed is different from the previous shape, If the hole size and type of the part to be machined are different from the previous ones, there is a problem in that the machining must be performed several times because different tools must be applied.

Such a problem is not only delayed in the hole machining speed of the three-dimensional pipe, but also increases in the number of processing apparatuses, occupies a large amount of work space, and requires a lot of manpower.

Accordingly, in the past, a device capable of completing all the machining operations in one apparatus during the machining of the three-dimensional pipe as described above is desperately needed.
