Sapphire glass is widely used in high-end consumer electronics window panels, precision instrument protective covers, optical windows, and smart wearable devices due to its high hardness (Mohs hardness level 9), high wear resistance, high temperature resistance, and excellent optical properties. However, materials with high hardness and brittleness are prone to edge breakage, cracks, and hidden cracks in traditional mechanical processing methods, especially in 1mm thin sheet processing, which requires extremely high equipment accuracy and process control.
Customer requirements:
For this project, the customer requires high-precision circular cutting of sapphire glass with a thickness of 1mm. The processed product must have strict dimensional tolerances, smooth edges without obvious chipping, and no hidden cracks inside. At the same time, the entire process needs to have stable and reliable mass production capacity to meet the standards of large-scale delivery.
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.
