Abstract

The invention relates to special polishing fluid for plastic soft metallic materials and a method for preparing the polishing fluid and belongs to the technical field of the polishing fluid. The polishing fluid is prepared from a ground material, a solvent and additives which are in a certain volume ratio, namely 2% of brightener, 3% of diamond micro powder, 15% of additives and 80% of kerosene. The method comprises the steps of: adding the diamond micro powder into melted lard or vaseline, and stirring uniformly; then, adding the kerosene, and cooling down to room temperature for standby; and adding stearic acid particles (C17H35COOH), vegetable oil and spindle oil into a clean vessel, stirring uniformly, adding the brightener, and uniformly mixing and stirring the solution, thereby obtaining the polishing fluid. The surface of a niobium alloy workpiece processed by the polishing fluid is uniform in mass, is free from polishing lines and can reach a mirror polishing effect. Meanwhile, the polishing fluid can play a role in cooling, lubrication, adsorption and washing during processing and can also be applied to the mirror polishing processing of similar plastic soft metallic materials, the operation is simple, the efficiency is high, the cost is low, and no pollution is caused.

Description

technical field [0001] The invention belongs to the technical field of polishing fluid, and is mainly used for ultra-precision polishing of plastic soft metal materials niobium and its alloys, and is also suitable for ultra-precision polishing of other similar plastic soft metal materials. The advantage of the polishing fluid is that it can effectively improve the quality of processed surfaces and Processing efficiency, at the same time, it can also play the role of cooling, lubrication, adsorption and cleaning in the processing process, suitable for aerospace manufacturing engineering and machinery manufacturing and other industries. Background technique [0002] Niobium and niobium alloys have become a new type of metal after steel, magnesium, and aluminum due to their excellent characteristics such as high strength, good plasticity, and corrosion resistance. They are widely used in aerospace, petrochemical, and medical fields. Its processing methods and Machining accuracy...
