In the field of glass deep processing, thickness and size are often the two major challenges that constrain the process. Cutting 10mm ultra white glass is already a challenge. It is almost impossible to cut a super large circular ring with a diameter of 1.1 meters on it while ensuring smooth edges and zero dimensional errors in traditional processing.
Customer requirements:
The core of the customer's cutting requirements this time is to challenge the dual limits of "ultra large size" and "ultra thick sheet": requiring the use of 10mm ultra white glass for one-time cutting and forming, obtaining a complete circular ring with a diameter of 1.1 meters and no splicing, while achieving a micrometer level contour accuracy of ± 0.01mm, edge control of ≤ 5 μ m, and a vertically smooth "optical grade" cross-section, achieving zero thermal impact and no polishing effect; In addition, it is necessary to meet the stability requirements for flexible production of irregular shapes, an increase in material utilization rate of more than 15%, and large-scale continuous production.
Solution:
Chuangkeda's "Infrared Picosecond Laser Glass Cutting Integrated Machine" achieves non-contact, low thermal impact, and edge free cutting with a high-energy density picosecond laser source, intelligent visual positioning system, and high-precision motion platform. During the cutting process, laser energy is evenly applied to the inside of the glass, forming a clean cross-section through the principle of cold cracking. The entire cutting edge can be directly assembled and used without the need for secondary polishing. For complex irregular paths, the intelligent control system of the equipment can operate accurately according to CAD drawings, ensuring that every arc and angle matches the design perfectly. The cutting accuracy of the equipment is as high as ± 0.01mm, with excellent verticality of the incision and a broken edge of ≤ 5 μ m; Supports cutting of any shape, whether circular, square, curved, or irregular contours, all can be completed in one go. At the same time, the automated processing platform equipped can achieve synchronous cutting of multiple pieces of glass, significantly improving production efficiency and providing high-quality and high-efficiency solutions for high-end glass precision processing.
Laser cutting effect display:
• Processing material: 10mm ultra white glass laser cutting 1.1m ultra large diameter circular ring
•Cutting accuracy: ± 0.01 mm
• Edge collapse control: ≤ 5 μ m
•Processing effect: The incision is smooth and flat, the curve transition is natural and smooth, and the finished product can directly enter the subsequent process without the need for secondary grinding or polishing treatment. The yield rate is ≥ 99%.
•Film integrity: Thanks to the extremely low heat affected zone, the coating layer remains intact at the cutting edge without any peeling or burn marks, preserving the original optical function of the glass.
• Processing advantages: Supports cutting of circular, square, and various shaped glass. R-angle, elliptical, and complex contours can be processed with high precision, ensuring stable mass production and strong dimensional consistency.
