Experimental equipment for surface finishing precise hole through gas-particle two-phase swirling flow

Based on the basic principle of the gas-particle two-phase swirling flow finishing, the paper designs and develops the experimental equipment for the bi-directional gas-particle two-phase swirling flow finishing with the adjustable machining parameters. With the novel processing method machining parameters have preferably been determined after the careful study of the characteristics and parameters of the spherical particle, the machining time and the adjustable machining parameters of equipment under the definite condition of a machined part and its requirement. It is evidence that the ideal technique can improve the quality of the surface of precise hole and the parts operational performance after its application to the machining of cross hole and blind hole.
