High borosilicate glass is widely used in experimental equipment, kitchenware, industrial equipment, and other fields due to its high temperature resistance, thermal shock resistance, and strong chemical stability. However, in the processing, especially for glass with a thickness exceeding 3mm, achieving precise R-angle cutting has always been a challenge in the industry. Traditional mechanical cutting is prone to cracking, chipping, or rough edges, requiring secondary polishing. This not only reduces efficiency but also increases material loss.
Customer requirements:
The customer has clear requirements for the processing of thick glass R-corners: firstly, high cutting accuracy, and each R-corner size must be consistent to ensure product assembly accuracy; Secondly, the edges should be smooth and free of cracks to avoid chipping and secondary polishing; Thirdly, it has high processing efficiency and is suitable for mass production, reducing time and cost; The fourth is stable quality of finished products, ensuring consistency and aesthetic appeal of bulk products.
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.
