Embodiment Construction

[0027] specific implementation plan

[0028] Attached below Figure 1~2 , the outer diameter is Φ400mm, and the height is the propeller of 60mm as an example, the present invention will be further described.

[0029] A kind of chemical mechanical polishing method of propeller and the preparation concrete operation of polishing liquid are as follows:

[0030] 1. According to the size of the propeller, choose a circular plastic container 2 with an outer diameter of Φ500mm and a height of 400mm. When the propeller 1 is installed, it is close to the bottom of the container 2, so the required height of the polishing liquid 3 only needs to be greater than the height of the propeller 2 by 60mm. Submerge it completely. In this example, the height of the added polishing liquid is 80mm, so it can be calculated that the total volume of the required polishing liquid is 15.7L. For the convenience of calculation, 16L is selected.

[0031] 2. According to the total volume of the polishing ...

Abstract

The invention belongs to the technical field of mechanical manufacturing, and discloses chemical mechanical polishing solution and polishing method for a propeller. The polishing method comprises thefollowing steps of rotating the propeller in chemical mechanical polishing solution, enabling the surfaces of propeller blades to be correspondingly subjected to alternating cycles of chemical corrosion and mechanical scraping removal effects with chemical reagents and abrasive particles in the polishing solution, and realizing precise polishing of all parts of the surfaces of the propeller blades. The polishing solution comprises an oxidizing agent, a dissolving agent, a corrosion inhibitor, composite additive, abrasive particles and water. Compared with traditional numerical control polishing and manual polishing, the polishing method is simple, high in polishing precision and good in flexibility, and particularly the polishing of propeller blade roots and impeller hub parts can be realized.

Description

technical field [0001] The invention relates to a chemical mechanical polishing liquid and a polishing method for propellers, belonging to the technical field of mechanical manufacturing. Background technique [0002] The propeller is a key part of the engine used in aircraft and ships. The propeller blades rotate in the air or in the water, thereby converting the rotational power into propulsion and providing power for the equipment. The surface quality of the propeller blade directly affects the propulsion efficiency of the engine, and also affects the vibration, noise and service life of the equipment. Therefore, it is very important to improve its processing quality. [0003] In order to meet the high-quality processing requirements of the propeller, the final polishing is usually required after the blank milling of the part. For the polishing process of the integral propeller, the main methods at home and abroad are: five-axis CNC milling, robot abrasive belt grinding ...
