The invention provides a microporous grain flow polishing liquid and a preparation method thereof. The polishing liquid is prepared from the following raw materials in parts by weight: 10-15 parts of grains, 42-60 parts of silicon oil, 42-60 parts of triethanolamine and 6-10 parts of silica gel. The preparation method comprises the step of evenly stirring the grains, silicon oil, triethanolamine and silica gel which are taken in the formula at a vacuum state so as to obtain the grain flow polishing liquid product, namely, adding the grains with different particle sizes in a soft grinding material medium for mixing and blending. The prepared grinding material has no precipitation phenomenon, good flowability and stability, high surface material removing rate and extremely low scratching and particle residue, and the larger the concentration is, the better the viscoelasticity is, thus the microporous grain flow polishing liquid is widely applied to the technical field of precision machining on the surface of a microporous runner of a work piece.
Description
technical field [0001] The invention relates to an abrasive flow polishing liquid, in particular to a microporous abrasive flow polishing liquid and a preparation method thereof. The polishing liquid can be used to polish specific parts to obtain nanometer-level surface precision. Background technique [0002] Abrasive flow processing technology achieves smoothing by reciprocating a soft abrasive medium loaded with abrasive viscoelastic body under pressure through the processed surface of the part. The abrasive particles in the abrasive flow are used as countless cutting tools, and the surface of the workpiece is repeatedly cut with its hard and sharp edges, so as to achieve a certain purpose of finishing. Any part where the abrasive flow passes will be smoothed, and the superiority of the abrasive flow processing technology is particularly prominent for the inner cavities of parts that are difficult for ordinary tools to touch. When the abrasive particles uniformly and gra...
