Comparison of the advantages and disadvantages of the three polishing processes-3Issuing time:2020-12-21 15:42Author:Allen AI Chemical polishing Chemical polishing is similar to electrolytic polishing. It is a method of removing wear scars and leveling by the selective dissolution of the uneven areas of the sample surface by the chemical etching of chemical reagents. The chemical polishing equipment is simple, capable of processing thin tubes, parts with deep holes and complex shapes, and high production efficiency. Chemical polishing can be used as a pretreatment process for electroplating, and can also be used directly after polishing with the necessary protective measures. The advantage is that the chemical polishing equipment is simple and can handle parts with more complex shapes; The disadvantage is that the polishing quality is not as good as that of electrolytic polishing. The polishing solution used has a short service life and is difficult to adjust and regenerate. During the chemical polishing operation, nitric acid emits a large amount of yellow-brown harmful gas, which causes serious environmental pollution. Precision casting is also called precision casting, lost wax casting,and its materials include stainless steel, various alloy steels, and carbonsteel. As a professional precision casting manufacturer, we also have strongmachining capabilities, with various Japanese imported and domesticallyproduced processing equipment to ensure that the product processingrequirements are qualified. |
