Common polishing materials are polishing wax, polishing wheel, polishing cloth wheel, polishing nylon wheel, wool wheel, thousands of impeller, sand belt, sandpaper, polishing powder, polishing fluid, grinding wheel and other types.

In the use of Magnetic polishing machine polishing products will pour the right amount of polishing liquid, grinding polishing liquid is different from the consolidation of abrasive, coated with abrasive another kind of "abrasive", abrasive in the loose agent uniform, free distribution. Abrasive polishing fluid can be divided into abrasive fluid and polishing fluid. General lapping liquid for coarse grinding, polishing liquid for fine grinding. Polishing liquid is usually used for the next process of abrasive liquid, the enterprise also called polishing liquid or abrasive liquid called polishing liquid.

Grinding liquid according to its effect mechanism: mechanical effect grinding liquid, chemical mechanical effect grinding liquid. Mechanical effect of abrasive liquid: diamond, B4C and so on as abrasives, through the addition of slack agent and other ways to slack into the liquid medium, so as to form a grinding effect of the liquid, known as diamond grinding liquid, boron carbide grinding liquid. Abrasive free distribution in lax liquid, the use of abrasive hardness than the principle of large hardness to complete the workpiece grinding, thinning. According to the appearance of abrasive, particle size and grinding liquid configuration, grinding equipment stability and other conditions, after the completion of grinding, the workpiece appearance is easy to leave large or small scratches. Therefore, the mechanical effect of the grinding liquid is generally used for rough grinding, and the subsequent need for fine grinding and polishing.

Chemical mechanical effect lapping liquid: chemical mechanical effect lapping liquid takes advantage of the principle of "soft grinding hard" in wear, that is, soft materials are used for polishing to complete high-quality polishing surface. It is a combination of mechanical grinding and chemical corrosion skills, and it forms a bright and flat surface on the surface of the ground medium with the grinding effect of ultra-fine particles and chemical corrosion effect. Therefore, Polishing fluid with Chemical Mechanical effects is also known as Chemical Mechanical Polishing fluid (CMP for short). In the presence of a certain pressure and polishing slurry, the polished workpiece moves relative to the polishing pad. By means of the organic combination between the abrasive effect of nanoparticles and the corrosion effect of oxidants, the polished workpiece is formed on the surface of the polished surface.
