Problems solved by technology
[0009] 1. In the existing polishing process, multiple parts are generally put together into an inclined canned drum when the parts are roughly polished, and the drum rotates, so that the parts and abrasives roll and collide randomly in the drum to remove surface bumps However, the shape of the parts is generally irregular, and once the parts collide, the surface of the parts will be damaged. Therefore, the rough throwing stage of the existing polishing process is not suitable for relatively precision parts;
[0010] 2. The existing polishing process method has a poor working environment, and the sand, iron filings, dust, etc. generated during the polishing process are not easy to clean or recycle, and will pollute the environment;
[0011] 3. In the existing polishing process, after the parts are polished, the parts are generally stored directly without subsequent treatment, and the surface of the parts is easily oxidized due to moisture;
[0012] 4. The existing polishing process method, if only by mechanical polishing, will cause certain damage to the surface of the part, and only by chemical polishing, it will easily cause the disadvantages of slow polishing speed, poor surface smoothness and poor polishing consistency

Embodiment Construction
[0053] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0054] like figure 1 As shown, a process method for polishing high-precision mechanical parts, it includes the following steps: S1, the first surface treatment: put the parts to be processed on the workbench, and treat the sand and dust attached to the surface of the parts ;S2, Rough polishing: Put the parts and abrasives after the first surface treatment into the rough polishing mechanism 1 for rough polishing; S3, Dust removal: While rough polishing, use the dust removal mechanism 2 to remove dust from the parts being polished Treatment; S4, fine polishing: after the rough polishing of the parts, use a fine polishing device to carry out fine polishing on the parts; S5, running water washing: in the process of fine polishing, it is necessary to use running water to wash the ...

The invention relates to the technical field of machining, in particular to a process method for polishing high-precision machine matching parts. The method comprises the following steps of S1, first-time surface treatment, wherein the parts to be machined are placed on a workbench, and sand grains, dust and the like attached to the surfaces of the parts are treated; and S2, rough polishing, wherein the parts obtained after to first-time surface treatment and a polishing material are placed in a rough polishing mechanism for rough polishing treatment. The method has the advantages that the parts cannot collide with one another in the rough polishing process, and it is avoided that the parts are damaged due to collision; the method is suitable for precise parts, and the applicability is improved; scrap iron can be conveniently recycled, the working environment becomes clean and tidy, and pollution to the environment is avoided; when the parts are stored, it is avoided that the surfaces of the parts are oxidized due to damp; and mechanical rough polishing increases the polishing speed and improves the surface flatness, and chemical fine polishing reduces damage to the outer surfaces of the parts caused by mechanical polishing.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a polishing process for high-precision mechanical supporting parts. Background technique [0002] Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. It is a modification process on the surface of the workpiece by using polishing tools and abrasive particles or other polishing media. [0003] Polishing is currently the main method to increase the surface finish of parts and reduce roughness. At present, the commonly used polishing methods for metal parts generally include: [0004] (1) Mechanical polishing: more important parts are manually polished with abrasive materials and electric tools; [0005] (2) Chemical polishing: chemical polishing is to achieve a bright and smooth metal surface through regular dissolution. During the chemical polishing pr...
