In addition, the cleanliness of the deep hole is poor, and burrs fall off under the impact of high-pressure oil in the working process, so that the service performance and the reliability are seriously influenced. And the abrasive flow processing is that the flowing abrasive passes through or crosses the processed surface of the zero-crossing piece under the extrusion action to grind the surface and the corners of the channel. By abrasive fluid polishing, better machining precision and surface finish can be obtained. For example, parts and accessories for automobiles are often processed by abrasive flow to achieve the purposes of optimizing product performance and prolonging product service life. However, in the existing abrasive fluid polishing and grinding equipment, only one workpiece can be stably clamped in one processing step, and particularly, the burr of the crossed deep hole with a large length-diameter ratio is cleaned, so that the batch production is difficult to realize at the early stage of meeting the quality requirement.
