In the fields of optical devices, display modules, and precision decoration, single-sided coated glass is widely used in filtering, reflection, anti glare, and decorative panels due to its combination of functionality and aesthetics. However, due to the extreme sensitivity of the coating layer to heat and stress, traditional mechanical processing often leads to problems such as film damage, edge breakage, and crack propagation when cutting circles, making it difficult to guarantee the yield of finished products.
Customer requirements:
The customer requests that the cut circular glass have a round contour, high dimensional consistency, smooth and delicate cuts, complete coating layer without peeling or ablation, and edge chipping controlled within a very small range, meeting the dual requirements of appearance and accuracy for optical grade applications.
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.
