Why choose a laser to cut diamonds? What are its advantages?
Laser cutting diamonds have great advantages and development prospects, using laser cutting diamonds can get smaller cuts and better results, choosing the right laser is crucial to the quality and efficiency of diamond cutting.
Advantages of laser cut diamonds
- Fine focusing
The laser beam can be focused to a very small point, resulting in a very fine kerf. This is more precise than traditional mechanical cutting methods and reduces material waste.
- High energy density
The high energy density of the laser is capable of rapidly melting or vaporizing the diamond, resulting in a very fine and smooth cut. The concentration of this high energy in a small area ensures that the cut line is very precise.
- Contactless Processing
Laser cutting is a non-contact process that reduces the physical and thermal stresses on the diamond, thereby reducing the risk of breakage and cracking. In contrast, mechanical cutting can put pressure on the diamond, leading to potential damage.
- Computerized control
Laser cutting is often used in conjunction with a computerized control system to achieve very intricate and detailed cutting patterns, and CAD software allows precise control of the laser path to ensure a consistent and high-quality cut.
- Automation and efficiency
Laser cutting can be integrated into automated systems to greatly increase productivity. Multi-axis laser cutting systems can quickly cut multiple faces or complex shapes, increasing processing speed and flexibility.
Advantages of different lasers
- UV lasers
– High absorption: UV wavelengths are highly absorbed in diamonds, enabling fine cutting.
– Small heat-affected zone: short wavelengths and short pulse widths reduce the heat-affected zone and minimize thermal damage to diamonds.
– High precision: suitable for microfabrication and high-precision cutting.
- Green light laser
– Higher absorption rate: green light has a higher absorption rate in diamonds than infrared light, better cutting effect.
– Moderate cost: Compared with UV and femtosecond lasers, green lasers have a lower cost.
- Infrared Lasers
– High power: suitable for fast cutting and large-area processing.
– Lower cost: Infrared lasers are less expensive than other types of lasers.
Recommendations for selection
– High accuracy and low thermal impact: UV lasers are preferred.
– Balancing cost and performance: Green lasers are a compromise, offering better cutting results and lower cost.
– Efficient large-area processing: infrared lasers are suitable for applications requiring high power and fast cutting.
Laser-cut diamonds enable smaller cuts and better results through high precision, high energy density, and contactless processing. Laser cutting offers an efficient and precise method of processing diamonds. The choice of laser needs to be based on the specific cutting needs, budget, and processing environment to ensure that the most suitable laser is selected to achieve the best cutting results.
