The method is characterized in that a workpiece, an abrasive and an additive in a certain proportion are placed in a container of a finishing machine, the workpiece and the abrasive move and grind each other by means of periodic vibration of the container, and the purpose of precisely grinding and processing the workpiece such as deburring, chamfering and deburring, polishing, cleaning and the like is achieved.
A certain amount of finishing waste liquid is generated in the finishing process of the workpiece. The polishing waste liquid is different from common grinding waste liquid, has large solid content and properties between muddy water and suspension liquid, and has certain stability. The particles in the polishing waste liquid can precipitate automatically under the condition of standing for a long time, but some particles are suspended in the supernatant. Because the processed workpiece is a steel product, the waste liquid contains a certain amount of iron ions and other heavy metal ions, such as manganese, chromium and the like. If the polishing waste liquid is directly discharged into the environment, solid particles deposit to cause the blockage of a drainage pipeline and deposit on a riverbed to influence an ecological system, particularly heavy metal ions in the polishing waste liquid have great harm, so that the direct discharge not only pollutes the environment, but also wastes water resources.
