The polishing process of Daily Necessities Mould(FURNITUREMOULD) is a very important step in the manufacture of the entire mould.
Mechanical polishing: Mechanical polishing is accomplished by cutting and removing protrusions and obtaining a smooth surface. Polishing methods generally use oil stone, wool wheel, sandpaper, etc., mainly by hand. Some special parts of the rotor surface require the use of a turntable, and if other tools require high surface quality, ultra-precision polishing may be required. Ultra-precision polishing uses a special abrasive. The polishing liquid contains abrasive pressure on the surface of the workpiece to be processed and rotates at high speed. This technology can achieve a surface roughness of Ra0.008μm, which is the most accurate polishing method.
Chemical polishing: Chemical polishing refers to first dissolving a material in a chemical medium having a convex portion to obtain a smooth surface. The main advantage of this method is that this method does not require complicated equipment, the complex shape of the workpiece can be polished, and many workpieces can be polished at the same time with high efficiency. The main problem is how to formulate a suitable chemical polishing solution. The chemical polishing surface roughness is generally 10 μm.
Electropolishing: Electropolishing and chemical polishing have the same basic principle of smoothing the surface by selectively dissolving small convex portions on the surface. It eliminates the effects of the cathodic reaction compared to chemical polishing.
