4JET's PEARLs - Laser Filamentation for Various Application Areas
4JET'S PEARLS
LASER FILAMENTATION FOR MANY APPLICATION AREAS
We call the laser-based glass filamentation PearlCut, because the filaments in the glass look like pearls strung on a string. What could be more obvious than to call our laser systems PEARLs. Our PEARLs combine filament based glass cutting and CO2 laser cutting in one processing head. Filaments are used to weaken the glass, which is then separated by heating, expansion and the generation of tensile stress. Where cycle times require it, the two processes can be divided into 2 PEARLs arranged one behind the other. It is also conceivable to subsequently apply a mechanical breaking process to a PEARL filament process. Our PEARLs can be used for glass cutting in a wide range of applications and industries, e.g.:
cover glasses for a wide range of electronic applications
cutting transportation glass for trains or cars, i.e. interior or exterior glass (mirrors, side windows, windscreens, etc.)
specific architectural glass like smart windows
or technical glass for e.g. optical substrates
SCALABLE IN SIZE AND WITH OPTIONS ACCORDING TO YOUR REQUIREMENTS
The PEARLs are based on granite, which offers inherent accuracy and long-term stability. The coefficient of thermal expansion of granite is 4 times lower than that of steel. This guarantees a sustainable production of high precision and high quality products. The specific tuning of the axis controllers not only results in a high cutting speed, but also in excellent path accuracy to achieve high-precision outer contours in the end product. An optional autofocus offers further advantages with regard to the robustness of the process window without having to accept a loss of process speed.
Our PEARLS are currently available in three versions with three standard working ranges. The length of the L and XL systems is scalable. Other sizes on request!
1.5 m width and length 0.85 m as PEARL M
1.5 m wide and scalable in length as PEARL L
2.2 m wide and scalable in length as PEAR XL
PEARL M
The PEARL M substrate table has been developed as a reliable and cost-effective base for the precise cutting of small to medium-sized glass substrates into individual products. The PEARL M substrate table can be configured to process ultra-thin glass with a thickness of approximately 30 µm up to a glass thickness of 8 mm. Various laser and optical packages can be integrated to optimize performance depending on glass thickness and coating.
An optional carrier allows filamenting and separation in one machine, saving space and additional costs for a second machine. A full automation option including a glass carrier rotation and glass waste disposal is available to minimize operating costs.
