Description

technical field [0001] The invention relates to the technical field of ultra-precision polishing, and more specifically, to an inner cylindrical surface hydraulic cavitation enhanced abrasive flow polishing system. Background technique [0002] In some special applications in the fields of aerospace, bioengineering, electronic information, etc., a cylindrical tubular workpiece with a circular cross section is required, and the inner cylindrical surface must have a high surface roughness during use. And there can be no processing deterioration layer and subsurface damage. The fluid polishing method uses extremely flexible fluid as the abrasive driving medium, which can effectively avoid subsurface damage caused by uneven abrasive force, and is widely used in the polishing of various parts. However, due to the weak driving force of the flexible fluid, the polishing efficiency of the fluid polishing method is low, especially for metal round tube parts that have undergone surfa...
