In the era of pursuing ultimate lightweight smart wearables, watch cover glass is not only a protective layer, but also the intersection of technology and aesthetics. From circular dials to irregular "full screen" designs, complex contours pose a severe challenge to cutting techniques. Traditional CNC machining is not only limited in efficiency when facing ultra-thin and high hardness glass, but also poses hidden killers of yield, such as microcracks and edge breakage.
Customer requirements:
A certain smart wearable brand manufacturer encountered a difficult problem in developing a new full curved screen watch: traditional CNC machining not only has low efficiency when facing irregular cutting of 2mm glass, but also has edge breakage problems, resulting in a yield rate of less than 60%, seriously affecting the new product launch plan. The customer urgently needs a processing solution that can ensure edge strength and achieve efficient cutting of any irregular shape
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.
Cutting effect display:
• Processing material: 2mm watch cover glass
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%.
• 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.
