In the current wave of manufacturing, glass laser cutting machines are quietly changing the production mode of traditional industries with their unique technological advantages. The widespread application of glass laser cutting machines, from architecture to automobiles, from household appliances to electronics, is driving innovation and development in the industry.

Glass cutting is a technical task that requires high precision and quality. Laser cutting technology has gradually become the mainstream choice for glass cutting due to its non-contact processing, high precision, and strong controllability. Among various laser technologies, ultraviolet laser, CO2 laser, and femtosecond laser are the three most commonly used types for glass cutting. So, which type of laser cutting glass * * *? This article will explore the performance and applicability of these three lasers in glass cutting through comparative analysis.

UV laser cutting of glass

Advantage:

·High precision processing: UV laser cutting can achieve micro - or even nano level processing accuracy, suitable for glass cutting with extremely high precision requirements.

·Small heat affected area: The heat affected area of ultraviolet laser is very small, suitable for processing heat sensitive materials, and can reduce glass deformation and cracks caused by thermal stress.

·Non contact cutting: Laser cutting is a non-contact processing method that does not cause mechanical stress on the workpiece and is suitable for manufacturing glass products that require high surface smoothness.

·High flexibility: The UV laser cutting machine can process graphics imported from software without the need for mold opening, and can flexibly meet the processing needs of various complex graphics.

Disadvantages:

·High equipment cost: The price of high-end UV laser cutting machines is relatively high, which may increase production costs.

·Maintenance cost: The laser optical path system is relatively precise and requires frequent maintenance to maintain cutting quality.

CO2 laser cutting of glass

Advantage:

·High power: CO2 laser has high power and can stably cut glass of a certain thickness.

·Smooth cutting section: CO2 laser outputs continuous laser, and its cutting section effect is relatively smooth during cutting.

Disadvantages:

·High thermal impact: The thermal impact area of CO2 laser is relatively large, which may cause glass deformation and cracking.

·Not suitable for thin glass: Due to the beam characteristics of CO2 laser, it may not be suitable for cutting extremely thin glass.

·High equipment cost: The price of CO2 laser cutting machines is relatively high, and maintenance costs are also relatively high.

Femtosecond laser cutting of glass

Advantage:

·Ultra short pulse width: The duration of femtosecond laser pulses is extremely short, usually in the femtosecond (10 ^ -15 seconds) range, which means that the interaction time between the laser and the material is very short, further limiting the range of thermal effects and improving cutting accuracy.

·High precision and high speed: Femtosecond laser cutting machines can perform high-precision and high-speed cutting operations, significantly improving work efficiency while ensuring cutting quality.

·Cold processing characteristics: The pulse width of femtosecond laser is extremely short, and the heat affected zone is very small, making it suitable for ultra-fine marking, engraving, and cutting of materials, known as laser cold processing.

Disadvantages:

·Expensive equipment: Femtosecond laser cutting machines are high-precision equipment, expensive, and require professional maintenance and operation.

·Technical complexity: Femtosecond laser cutting technology is relatively complex and requires professional technicians to operate and maintain it.

In summary, ultraviolet laser, CO2 laser, and femtosecond laser each have their unique advantages and disadvantages in the field of glass cutting. The choice of laser technology depends on specific cutting requirements, cost budget, and technical level.
