Abstract: PURPOSE:To provide a machining head where its structure is simple and its nozzle position can be easily adjusted by providing a pressure chamber between a nozzle and a housing, and adjusting the pressure of the compressed air to be supplied to the pressure chamber, and thereby adjusting the nozzle holding position. CONSTITUTION:A control device 15 elevates/lowers a housing 5 by means of an elevating mechanism based on the prelisminarily stored data, and locates a converging lens 4 at the position where the focal position is optimum. At the same time, the control device 15 transmits the selected pressure of the compressed air to a pressure adjusting mechanism 8 based on the data on the preliminarily stored pressure values of the compressed air and the height of a nozzle 6 so as to cope with the position of the covnerging lens 4.
