The technology of gas-particle two-phase compulsive circumfluence finishing is another kind of finishing method, which is proposed on the basis of spiral gas flow finishing and liquid-particle two-phase compulsive circumfluence finishing. The process of this method is the gas with a certain pressure was pushed through the circulation occurs device, compulsive circulation is formed by the gas. It stimulates particles to make circulation movement. The particles can collide, scratch and rolling the hole surfac...
