2.Introdution of product

   Mechanical polishing relies on the grinding and rolling action of very small polishing powder to remove extremely thin metal on the surface of the sample. Polishing is often used to enhance the appearance of products, prevent contamination of instruments, remove oxidation, create a reflective surface, or prevent corrosion. In metallurgy, polishing is used to form flat, defect free surfaces for microscopic examination of metals. Silicon based polishing pad or diamond solution can be used in polishing process.

3.Features and principle 

    The function of polishing is to reduce the surface roughness of the workpiece so as to get bright and smooth surface. This paper mainly explains the characteristics and principles of mechanical polishing for you.

Mechanical polishing is the modification and deburring of workpiece surface by using flexible polishing tools and abrasive particles. Polishing can not improve the dimensional accuracy or geometric accuracy of workpiece, but to obtain smooth surface or mirror gloss. Mechanical polishing relies on the grinding and rolling action of very small polishing powder to remove extremely thin metal on the surface of the sample.

   During mechanical polishing, the polishing wheel on the polishing machine rotates at a high speed. The operator presses the surface of the polished piece on the polishing wheel with appropriate pressure. The high temperature is produced by the friction effect, which makes the polished surface easily deformed and form a layer of "processed metamorphic layer". Under the action of rotating friction, some of the convex parts of the surface are cut off on the one hand, and the surface of the metal parts will also produce plastic deformation. The convex parts are pressed or moved for a certain distance to fill the depression. The leveling process of the clipping and recess is carried out at a high speed and on a large scale, coupled with the brightening effect of the polishing paste, which results in a smooth and bright surface of the original coarser parts.

    Polishing can not improve the size accuracy or geometric accuracy of the workpiece, but for the purpose of getting smooth surface or mirror gloss, and sometimes to eliminate gloss (extinction). Polishing is usually used as a polishing tool for mechanical polishing. The polishing wheel is usually made of multi-layer canvas, non woven fabric, felt or leather, and the two sides are clamped with metal circular plates, and the flange is applied to the polishing agent, which is made of fine powder and grease. During polishing, the high speed rotating polishing wheel (round speed above 20 m / sec) presses the workpiece to the workpiece, making the abrasive rolling and micro cutting on the workpiece surface, thus obtaining a bright surface with a surface roughness of Ra0.63 to 0.01 microns; when the non fat polishing agent is used, the light surface can be reduced to light. Improve the appearance.

    A large number of steel balls, lime and abrasives are placed in the tilted tank drum during rough throwing. When the roller is rotated, the ball and the abrasive are rolled into the cylinder randomly to achieve the purpose of removing the surface convex front and reducing the surface roughness, and the allowance of about 0.01 millimeters can be removed.
