There are many types of surface processing processes for metal jewelry, including gold engraving, hammering, wire drawing, sandblasting, batching, laser engraving, electroplating, etc.
These processes can not only increase the layering and beauty of metal jewelry but also significantly enhance the value of jewelry. Today, we will introduce a new method of metal jewelry processing - using ultrasonic technology to assist metal surface processing.
Principles and applications of ultrasonic technology
The ultrasonic processing system converts high-frequency electrical energy into mechanical vibrations during the processing process.
When using MCD diamond single crystal tools for processing, the ultrasonic processing system generates 16k-60kHz vibrations per second, causing the tool and the workpiece to separate periodically, and leaving nano ironing knife marks on the surface of the workpiece.
These Tools marks form a grating structure, which presents rainbow-like bright colors under the refraction of light by dynamically adjusting the spacing and angle of the grating, creating a unique visual effect.
Processing advantages of using ultrasonic technology
1. Reduce cutting force and cutting temperature: Ultrasonic-assisted processing technology effectively reduces the main cutting force and cutting temperature.
2. Reduce material damage and stress: This technology can reduce damage to the subsurface layer of hard and brittle materials and processing stress.
3. Improve surface quality: Ultrasonic-assisted processing reduces surface roughness and improves the surface integrity of the workpiece.
4. Extend tool life: Ultrasonic-assisted processing can extend tool life due to low friction resistance and small deformation during processing.
Characteristics of MCD diamond single crystal tools
- High finish: Suitable for non-ferrous metal processing, can achieve the mirror effect.
- Long life: MCD diamond has high hardness and wear resistance.
- Low friction resistance: Sharp cutting edge and low friction resistance make deformation small during processing, reduce cutting force, and not easily cause built-up edge.
- High thermal conductivity: It has a low thermal expansion coefficient, which is conducive to the processing of precision parts.
Use MCD diamond tools and ultrasonic technology to assist in processing effect
Compared with traditional processing methods, the use of ultrasonic-assisted processing can significantly improve the surface quality of the workpiece.
The surface roughness after processing reaches Ra＜0.8μm, and the surface brightness, reflection effect, and colorful effect are improved. In addition to gold, this unique processing technology can also be applied to the surface processing of different metal materials such as silver and aluminum alloy.
The application of ultrasonic technology in metal jewelry processing not only enriches the processing technology but also enhances the visual effect and market value of jewelry. Through this innovative technology, future metal jewelry will be more colorful and full of artistic charm.
