ABSTRACT:
A powder beam working system for working a surface to be worked of an object to be worked by dispersing fine particles in high-pressure gas and projecting a solid-gas two-phase flow thus produced to the surface of the object to be worked which comprises means which temporarily stores the fine particles, a dispersing chamber which forms a portion of a flow path for the high-pressure gas and sending means which sends out the fine particles stored in the storing means into the dispersing chamber at a predetermined rate as the fine particles are in a solid phase state, thereby being capable of adjusting a flow rate of the produced solid-gas two-phase flow and an amount of the fine particles contained in the solid-gas two-phase flow easily and individually.
