Laser cutting is a precision cutting method widely used in industrial manufacturing. Laser cutting allows a level of accuracy unmatched by any other cutting method. A high-powered laser is directed at the material to be cut. The material burns, melts or vaporizes, leaving a high quality finish.
Apart from the common materials such as wood, plastic and metal, laser cutting is also widely used in the processing of glass. Glass has become an important component of a large number of applications. Its use is not just restricted to windows and bottles but has expanded to telecommunications and information technology. These modern applications require a higher level of accuracy and precision that can not be matched by traditional methods.
Traditional glass cutting methods make direct contact with the surface, increasing chances of unwanted scratches and abrasions. Moreover, material losses and glass dust are other problems faced in the conventional process.
The use of lasers has revolutionized the art of glass cutting. The laser beam is used to produce highly complex and accurate shapes with a fine edge finish. The power of the laser beam ranges between 1000 to 2000 watts. Most laser cutters are integrated into an enclosed machine with state-of-the-art software. Since the laser used is a "class 4" laser, care is taken to keep the user away from direct contact. The CO2 laser is the most common device used in glass cutting.
The advantages of laser cut glass are many. Apart from the superb quality edges, flaking, chipping and micro-cracks are almost completely eliminated. Moreover, laser cut glass is up to 3 times more durable than conventional cut glass. Since cutting oil is not used in the process, the glass washing process is also minimized.
Laser glass cutters can be used to cut glass of any thickness with an equal amount of accuracy. From decorative articles and frames to quartz crystal oscillators and display glasses, the use of these devices is limitless.
