What is the purpose of surface polishing?

Surface polishing is a key technology widely used in the manufacturing industry. Its purpose is not only to make the product more beautiful but also to improve product performance, extend service life, and other goals. For many customers, the quality of surface polishing directly determines the market value and user experience of the product. Whether it is electronic products, automotive parts, aviation equipment, or medical equipment, polishing technology plays an important role. From the smoothness of the surface to the precise fit between parts, surface polishing not only improves the appearance of the product but also has significant optimization in terms of functionality and safety. This article will focus on the multiple purposes of polishing, starting from the actual needs of customers, deeply explore why surface polishing is crucial to products in various industries, and specifically explain its application examples in multiple industries.

How does polishing eliminate surface defects?

During the product manufacturing process, tiny burrs, scratches, or other surface defects are inevitable, and these subtle defects may cause problems during the use of the product. Polishing is one of the best ways to eliminate these surface defects. For example, the surface of metal parts in the machining industry is prone to burrs during production. These burrs not only affect the assembly of parts, but also generate additional friction during operation, and even cause component failure. Through polishing, surface defects can be completely removed and product quality can be significantly improved.

Polishing not only plays a role in metal products but also in the manufacturing process of plastic parts and composite materials. Polishing can also remove tiny defects remaining on the surface and make the surface smoother and flatter. For example, in the manufacturing process of medical devices, surface polishing can ensure that the surface of the product is free of any burrs, reduce friction and irritation that may be caused when in contact with patients, and improve product safety.

Extension:

• Aircraft engine turbine parts are polished to remove tiny manufacturing defects on the surface to ensure stable operation under high pressure.
• Plastic injection molding products are polished to eliminate minor defects left by the mold to ensure a smooth surface and improve appearance and performance.

How does polishing improve the protectiveness of the surface?

Surface polishing can also effectively improve the corrosion resistance and oxidation resistance of the product. Especially for equipment exposed to harsh environments for a long time, polishing is an essential process. In the oil and gas industry, pipelines, valves, and other equipment need to have strong corrosion resistance on their surfaces because they work in high temperature, high pressure, and chemical corrosion environments all year round. Through polishing, the metal surface is denser and it is difficult for corrosive substances to enter the material, thereby extending the service life of the equipment and reducing downtime and maintenance costs.

The shipbuilding industry is also highly dependent on polishing technology, especially the polishing of the hull shell, which can effectively improve its ability to resist seawater corrosion and reduce wear and damage during long-term operation in seawater. In addition, surface polishing can also improve the hygiene standards of food processing equipment and medical devices to ensure that the surface will not breed bacteria and pollutants due to long-term use.

Extension:

• After polishing, chemical equipment can better resist the erosion of various chemicals, extend the service life of equipment, and reduce enterprise maintenance costs.
• After polishing, the hull of the ship significantly enhances its corrosion resistance, ensuring safe operation in harsh marine environments for a long time.

How does polishing ensure precision fit?

In the precision manufacturing industry, especially in the fields of electronics, optics, aerospace, etc., surface polishing not only affects the smoothness of the product surface but also directly determines the precision fit between parts. Customers want the fit between parts to be accurate and correct, reducing the risk of loosening or jamming during use. Polishing ensures that the fit between parts reaches micron-level precision by accurately removing the excess part of the material surface.

For example, in the production of medical devices, artificial joints can perfectly match human tissues after fine polishing, reducing friction and wear, thereby improving patient comfort and the life of artificial joints. In the field of optical instruments, the surface polishing of lenses can improve their transparency and optical performance, making them play a more stable role in high-precision measurements.

Extension:

• After polishing, the movement parts of precision watches ensure the precise fit between gears, improving the durability and accuracy of the product.
• Polishing reduces light scattering and improves image quality and observation accuracy.

How does polishing improve cleanliness and hygiene requirements?

In the pharmaceutical equipment and food processing industries, surface polishing is not only for aesthetics but also for improving hygiene standards – this is crucial for many industries, especially the pharmaceutical and food processing industries! Because surface polishing can significantly improve cleanliness and hygiene levels. Equipment with smooth and non-porous surfaces can prevent the accumulation of bacteria, dirt, and chemical residues, ensuring qualified hygiene conditions. Food processing equipment is polished to avoid the adhesion of food residues, thereby reducing the possibility of bacterial growth and meeting strict hygiene standards.

Polishing also plays an important role in medical device manufacturing. For equipment such as surgical instruments, implants, and catheters, the smoothness of the surface determines whether it can safely and effectively contact human tissue. Polished surgical tools reduce the chance of bacterial adhesion and reduce the risk of infection.

Extension:

• After polishing, the surface of pharmaceutical production equipment is smoother and flatter, reducing the risk of contamination in drug production and meeting the hygiene requirements of drug production.
• After polishing, dairy processing equipment prevents the adhesion of fat and residues in dairy products, making it easier to clean and disinfect.

In summary, the benefits of polishing are as follows:

1. Improve product appearance
2. Improve surface performance
3. Extend equipment life
4. Reduce energy consumption and friction
5. Meet strict hygiene standards
6. Improve safety and reliability
