In the machinery manufacturing industry, the quality of lathe parts directly affects the performance and service life of the whole equipment. And polishing as an important process to improve the surface quality of lathe parts, more and more attention by enterprises. In this paper, we will discuss the importance of polishing lathe parts and its methods, aiming to improve the overall level of China’s machinery manufacturing industry-The method of lathe parts polishing.

First, the importance of lathe parts polishing

  1. improve surface quality: polishing can remove burrs, scratches and other defects on the surface of the lathe parts, so that the surface of the parts to achieve a high degree of flatness, smoothness, and improve its appearance. 2. improve machining accuracy: the polishing process is a very important process to improve the machining accuracy.
  2. improve machining accuracy: polishing process, you can through the parts surface grinding, extrusion and other effects, eliminate the stress generated during processing, reduce the deformation of the parts, so as to improve machining accuracy.
  3. Enhance wear resistance: Polishing can make the surface of the parts to form a layer of dense oxide film, improve the wear resistance of the parts, extend the service life.
  4. Improve product competitiveness: high-quality lathe parts can enhance the overall performance of the product, enhance the competitiveness of the product in the market.

Second, the method of polishing

  1. manual polishing: manual polishing mainly relies on the operator’s skillful techniques and experience, the use of sandpaper, polishing paste, etc. on the surface of the parts for grinding, polishing. This method is suitable for small quantities, complex shapes of parts.
  2. mechanical polishing: mechanical polishing utilizes polishing machines, grinding wheels and other equipment to polish parts. According to the type of polishing machine, it can be divided into three stages: rough polishing, medium polishing and fine polishing. Mechanical polishing is suitable for large quantities, regular shape parts.
  3. chemical polishing: chemical polishing is through a chemical reaction to generate a layer of oxide film on the surface of the parts, so as to achieve the purpose of polishing. This method is applicable to the surface requires a high degree of flatness, smooth parts.
  4. Electrochemical polishing: Electrochemical polishing utilizes an electrochemical reaction in an electrolyte solution to polish the surface of the part. This method is applicable to a variety of materials, shape of the parts, and polishing effect is better.

Third, the polishing notes

  1. before polishing should ensure that the surface of the parts clean, no oil, moisture and other debris.
  2. Select the appropriate polishing method and polishing agent, according to the parts material, shape and other factors.
  3. Polishing process should control the polishing strength, to avoid excessive polishing parts surface damage.
  4. after polishing should be timely cleaning parts, remove the surface of the polishing paste and other residues.

In short, lathe parts polishing is important in improving the quality of parts and extending their service life. Mastering the appropriate polishing method, and polishing in strict accordance with the operating procedures, is the key to improve the level of China’s machinery manufacturing.
