The Working Environment and Factors Influencing Surface Polishing Performance of Hardware Accessories Polishing

The polishing process can be divided into rough polishing and fine polishing, and rough polishing and fine polishing are completed separately in two working locations. Hardware accessory polishing, that is, the rough grinding processing location and fine polishing processing location are separated, and attention should be paid to cleaning the remaining sand particles on the surface of the workpiece in the previous process.

Generally, after rough polishing with oilstone and 1200 # sandpaper, the workpiece needs to be transferred to a dust-free room for polishing to ensure that there are no dust particles sticking to the surface of the mold in the air. Accuracy requirement is at 1 μ Above m (including 1 μ m) The polishing process can be carried out in a clean polishing room. If more precise polishing is carried out, it is necessary to clean the space in Jue, as dust, smoke, dandruff, and saliva may scrap high-precision polished surfaces.

Stainless steel will form a layer of black or gray oxide skin on its surface after hot processing, mechanical processing, or storage for a certain period of time. It is polished by Kunshan, and its main components are cr2O3, nio, and very insoluble feo, cr2O3. Their presence not only affects the appearance quality, but also affects the product's performance. Therefore, appropriate measures should be taken to remove them. There have been many reports on surface treatments such as oxide skin removal and polishing of stainless steel. Stainless steel polishing, as a mature surface treatment method, has been widely used. Hardware accessory polishing can further improve the corrosion resistance and brightness effect of stainless steel.
