Stainless steel has been widely used because of its high decorative advantages, especially in medical appliances, tableware and other aspects of the popularization and promotion of stainless steel polishing materials needed are generally:? Polishing wax, sisal wheel, nylon wheel, cloth wheel, wind wheel, wire cloth wheel? and so on. Next we will introduce you to the stainless steel grinding and polishing methods and stainless steel polishing notes?
First, stainless steel grinding and polishing methods
If the surface is not flat, first use the angle grinder fitted with an emery cloth polishing piece to level the surface. Then use the angle grinder loaded with felt polishing pads, first thrown on the polishing wax, so that the felt pads are covered with wax and then go to polish the surface that needs to be polished.
1, mechanical polishing
Mechanical polishing is by cutting, plastic deformation of the surface of the material to remove the convexity of the polished surface and get a smooth surface of the polishing method, the general use of oleander, wool wheel, sandpaper, etc., mainly hand-operated, special parts, such as rotating body surface, you can use the rotary table and other auxiliary tools, the surface quality of the requirements of the high surface can be used in the ultra-precision research and polishing methods
2 Chemical polishing
Chemical polishing is to let the material in the chemical medium surface microscopic convex part of the concave part of the preferential dissolution, so as to get a smooth surface. The main advantage of this method is that it does not require complex equipment, can be polished complex shape of the workpiece, can be polished at the same time a lot of workpieces, high efficiency. The core problem of chemical polishing is the preparation of polishing solution. Chemical polishing to get the surface roughness is generally a few 10?m.
3, electrolytic polishing
Electrolytic polishing and chemical polishing of the same basic principle, that is, by the selective dissolution of the material surface of the small protruding parts, so that the surface is smooth. Compared with chemical polishing, can eliminate the influence of cathodic reaction, the effect is better. Electrochemical polishing process is divided into two steps:
(1) Macro leveling dissolution products to the electrolyte diffusion, the material surface geometric roughness down, Ra>1?m.
4, microlight leveling anodic polarization, surface brightness increased, Ra <1?m.
Second, stainless steel polishing notes
Grinding operation top with sandpaper or sanding paper, or with the surface of the material.
There have been problems with the use of aluminum oxide as an abrasive, some of which are due to pressure difficulties. Any abrasive parts of the equipment, such as: abrasive belts and grinding wheels, etc., should never be used for other non-stainless steel materials before use. Because this will contaminate the stainless steel appearance. Can be used in conjunction with the Dongzhan Xinbo polishing wax.
In order to ensure the consistency of the appearance of the process, the new grinding wheel or abrasive belts should first be tried on the same composition of the waste material, so that the same products for comparison.
The above is today to introduce you to the stainless steel grinding and polishing methods as well as stainless steel polishing considerations of the full knowledge is introduced to you here, I hope to bring you help.
