Laser cutting is an advanced manufacturing technique that involves the use of a high-energy laser beam to cut materials, including metals, plastics, and glass. In recent years, glass laser cutting has gained significant popularity due to its precision and efficiency, making it a preferred choice for a wide range of applications. Among various glass laser cutting technologies, Han’s Laser stands out for its unique capabilities and advantages.

The Han’s Laser glass cutting is based on the use of a high-power laser beam to heat and melt the glass material, followed by a cooling process that results in a clean and precise cut. The principle is based on the absorption of laser energy by the glass material, which leads to the generation of thermal stress and thermal shock. The thermal stress and shock cause the glass to fracture along a pre-determined cutting line, resulting in a smooth and precise cut.

The Han’s glass laser cutting offers several advantages over traditional glass cutting methods.

Firstly, it provides a higher degree of precision, allowing for the cutting of complex shapes and designs with high accuracy. This makes it suitable for applications such as electronics, automotive, and aerospace, where precision is crucial.

Secondly, the process is highly efficient, enabling faster production rates and reduced labor costs. This is particularly beneficial for mass production applications, where high volumes of glass components need to be produced within a short time.

Lastly, the laser glass cutting minimizes the heat input into the glass material, reducing the risk of thermal damage or distortion. This ensures that the cut edges are clean, smooth, and free from any thermal defects.

The laser glass cutting is suitable for cutting a wide range of glass materials, including tempered glass, laminated glass, and low-E glass. The process is highly customizable, allowing for the cutting of various thicknesses and shapes. Additionally, the glass laser cutting Principle can be combined with other laser technologies, such as laser engraving and marking, to provide a comprehensive glass processing solution.

To implement the laser glass cutting, a high-power laser system is required. The laser system consists of several components, including a laser source, optics, and a cutting head. The laser source generates a high-energy laser beam, which is directed towards the glass material using optics. The cutting head, which is equipped with a nozzle, controls the delivery of the laser beam to the glass surface, ensuring precise cutting and minimal heat input.

The cutting process involves several steps.

Firstly, the glass material is positioned on a cutting bed, which can be either static or moving. The cutting bed provides a stable platform for the glass material during the cutting process.

Secondly, the cutting parameters, such as laser power, cutting speed, and focus, are set based on the thickness and type of glass material. This ensures that the laser energy is optimized for maximum efficiency and precision.

Thirdly, the laser beam is directed towards the glass surface, creating a localized heating and melting of the glass material. The thermal stress and shock generated cause the glass to fracture along a pre-determined cutting line, resulting in a smooth and precise cut. Lastly, the cut edges are cooled using a jet of compressed air, ensuring that they are clean and free from any thermal defects.
