Most people will have this question: now many businesses are promoting their products using the polishing process, but most do not know what is the polishing process in the end?

 In fact, the polishing process is the name of the product is the use of polishing equipment and polishing materials on the surface of the product fine processing of the specific process. The polished product has a high finish and brightness.

Now polishing technology is divided into: (drum polishing machine, centrifugal polishing machine, magnetic polishing machine, vibration polishing machine) mechanical polishing, electrolytic polishing, chemical polishing,

 (Drum polishing machine, centrifugal polishing machine, magnetic polishing machine, vibration polishing machine) mechanical polishing details and principles:

  Large-scale production of bearing steel ball, often used roller polishing method. Rough cast when a large number of steel balls, grinding fluid and abrasive in the container, the machine starts, so that the ball and abrasive in the cylinder and random rolling collision in order to achieve the surface of the surface to reduce the surface roughness of the purpose,

  Can remove the margin of about 0.01 mm. When pouring in the barrel into the ball and fine polishing abrasive, gloss agent, re-grinding the corresponding time can be dazzling bright surface.

  The polishing of the precision thread is carried out by immersing the machined surface in the polishing solution. The polishing liquid is mixed with the chromium oxide powder and the emulsion liquid with the grain size W5 ~ W0.5.

  The polishing wheel is made of finely made of degreased wood or specially made fine felt. The trajectory of the polishing wheel is uniform and dense. The surface roughness after polishing is not more than Ra0.01 micron. Under the microscope, 40 times under magnification Not any surface defects.

    Mechanical polishing is polished on a special polishing machine, polishing and rolling by polishing and other grinding materials and grinding between the relative grinding and rolling to eliminate the wear marks, divided into coarse polishing and fine polishing.

  The use of flexible polishing tools and abrasive particles or other polishing media on the surface of the workpiece modified processing. Polishing can not improve the workpiece size accuracy or geometry accuracy, but to get a smooth surface or mirror gloss for the purpose,

  Adding the appropriate polishing solution may cause the metal surface to recover more quickly than the original luster, and will not leave any scars.

Electrolytic polishing principle and process:

  Stainless steel electrolytic polishing principle is recognized as the main mucosal theory. The theory is mainly: the metal ions on the workpiece and the phosphoric acid in the polishing solution to form a layer of phosphate film adsorbed on the surface of the workpiece, the mucosa in the convex at the thin,

  Concave thick, because the protrusion of high current density and dissolve fast, with the mucosal flow, bumps continue to change, the rough surface is gradually leveling process.

  Electrolytic polishing process: degreasing - washing - rust - washing - electrolytic polishing - washing - neutralization - washing - passivation - packaging

Chemical polishing:

  Chemical polishing for the polishing requirements of the situation is not high, the need for heating use, now the current technology, if it is able to use the above three kinds of polishing do not use chemical polishing method, because the chemical polishing effect is poor, the overall cost is higher.
