In today's manufacturing industry, with the continuous improvement of consumer requirements for product quality, finishing technology has gradually become an indispensable part of the manufacturing process. By adopting advanced finishing methods and technologies, enterprises can not only significantly improve the appearance quality, accuracy and performance of products, but also effectively reduce production costs and enhance market competitiveness. This paper will discuss the basic concepts, main types and application fields of finishing, and analyze its importance for the future development of manufacturing industry.
First. What is finishing?
Finishing refers to a more refined and complex processing process after rough machining, with the purpose of further improving the quality and dimensional accuracy of the surface of the part or component to meet the design requirements. It involves removing small amounts of material to correct shape errors, smoothing surfaces, or adding specific textures.
Two. The main types of finishing
1. Grinding: The process of using grinding wheels or other grinding tools to remove extremely thin layers of materials on the surface of the workpiece, suitable for metal and non-metal materials.
2. Polishing: Through physical or chemical means to make the surface of the object become smooth and bright technology, widely used in jewelry, optical lenses and other fields.
3. Electroplating/electroless plating: Using the principle of electrolysis or chemical reaction to deposit a layer of metal film on the base material to increase the functional characteristics of aesthetics, corrosion resistance and so on.
4. Laser processing: The use of high energy density laser beam for material cutting, welding, marking and other processing, with the advantages of fast speed and high precision.
5 Ultrasonic cleaning: The use of ultrasonic cavitation effect to remove dirt impurities on the workpiece, especially suitable for complex structural parts cleaning operations.
Third, the application field of finishing
- Automotive industry: Key components such as engine blocks and piston rods need to undergo strict finishing processes to ensure their working stability and service life.
- Electronic communication: Small precision components such as mobile phone shells and circuit board connectors rely on finishing technology to achieve miniaturization and high performance.
- Medical instruments: Surgical instruments, implants and other medical supplies must have extremely high precision and biocompatibility, which cannot be separated from advanced finishing technology.
- Aerospace: Special purpose products such as aircraft engine blades and satellite mirrors need to meet the requirements of use in extreme conditions, where finishing plays a crucial role.
Iv. Future Outlook
With the continuous emergence of new materials and new processes, as well as the development of intelligent manufacturing technology, the future of finishing will move towards a more efficient and environmentally friendly direction. For example, the intelligent control system optimized based on big data analysis and artificial intelligence algorithm can realize adaptive adjustment of parameter Settings, greatly reducing the debugging time; The new coating technology under the guidance of green manufacturing concept can reduce environmental pollution while extending product life.
