Abstract: A tool radius adjusting device executes an operation for adjusting the tool radius of a boring holder in parallel with execution of a machining program for executing an operation of a spindle head and an operation of a tool changer. A carrier control unit determines whether the tool changer is executing a tool changing process. When the tool changing process is not being executed, the carrier control unit allows the carrier device to execute an operation for picking the boring holder out from the tool magazine and an operation for returning the boring holder, of which the tool radius has been adjusted, to the tool magazine.

Abstract: Sealing in the sliding gap of a rotating valve is improved to smoothly rotate the rotating valve during replacement of a roller bit. A valve housing portion is formed behind a bit housing portion having an opening at the front of a main cutter spoke. A rotating valve is rotationally disposed as a rotating body in the valve housing portion. A bit case containing the roller bit is moved into the bit housing portion so as to protrude from a removable passage of the rotating valve, and then the bit case is fixed by a cotter member to support a drilling reaction force. Thus, the sliding gap of the rotating valve is disposed in the bit housing portion and the valve housing portion and is covered with the bit case.
