In the production of precision optical components and high-end decorative panels, single-sided coated glass is highly favored due to its unique optical properties and aesthetic appeal. However, when the thickness is as low as 1mm and it needs to be cut into elliptical or other irregular contours, traditional mechanical processing is often inadequate: the film layer is prone to damage, the edge breakage is difficult to control, and crack propagation leads to a sudden drop in yield.
Customer requirements:
The glass thickness required by the customer is only 1mm, and the surface has a precision functional coating layer. The processing requirements are extremely strict: the elliptical contour after cutting must be round and consistent in size, the incision must be smooth and delicate, and the coating layer must be complete without peeling or burning. In traditional CNC machining, the mechanical stress generated by tool contact can easily lead to the breakage of thin glass or the collapse of the coating layer, and the subsequent polishing process is even more time-consuming and laborious.
Solution:
With its high-energy density picosecond laser source, intelligent visual positioning system, and high-precision motion platform, Chuangkeda's "Infrared Picosecond Laser Glass Cutting Integrated Machine" achieves non-contact, low thermal impact, and edge free cutting. 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.
Cutting effect display:
• Processing material: "1mm coated glass" laser cutting ellipse
• 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.
