To provide space saving and facilitate additional processing work by making at least a part of the operating range of a teaching shaft and the operating range of a processing shaft common.
An X-shaft 12 having an X-shaft guide 11 is used in common for both of a Y-shaft 13 for processing and a Y-shaft 14 for teaching. The Y-shaft 13 for processing and the Y-shaft 14 for teaching move in the X- direction along the X-shaft 12. Therefore, processing operation and teaching operation are conducted in the identical range. The Y-shaft 13 for processing is provided with a torch unit where a plasma torch is supported, and the Y-shaft 14 for teaching is provided with a teaching unit where a teaching pointer is supported. The torch unit moves in the Y-direction along the Y-shaft 13 for processing. The teaching unit moves in the Y-direction along the Y-shaft 14 for teaching.
