PROBLEM TO BE SOLVED: To provide an additional processing head achieving a mechanism for supplying material powder to an infinitely-rotational nozzle part with a simple structure: and to provide a processing machinery with such an additional processing head.SOLUTION: An additional processing head includes: a nozzle part discharging material powder; a rotational member 76 on which a material powder passage 91 connected to a nozzle part and guiding the material powder to the nozzle part, and which rotates so that the nozzle part moves in a circumferential direction around laser beam radiated to a work; and a fixation member 71 on which a material powder passage 92 where the material powder is introduced is formed, and which is continuously set to the rotational member 76 in a rotary axis direction of the rotational member 76. The material powder passage 91 and the material powder passage 92 are communicated with each other between the fixation member 71 and the rotational member 76, and a material powder passage 93 annularly extends around the rotary axis of the rotational member 76 is formed.SELECTED DRAWING: Figure 10 |
