In a metal powder processing equipment where metal powder is sequentially laminated on a table inside a chamber and laser beam melting or electron beam melting, and shaping by a cutting tool (3) subsequently to the melting are performed, unmolded powder (6) remaining at the time of the melting and cut powder (6) generated by the cutting can be scattered by generating an air flow (5) with respect to the cutting tool (3) from either side of a main shaft (1) or a tool holder (2). As a result, the life of the cutting tool (3) is prolonged and the quality of a cut surface can be improved. |
