In the glass deep processing industry, 10mm thick European grey glass is considered a high difficulty material due to its high hardness and stress sensitivity. Slight uneven stress during processing can easily lead to edge breakage, hidden cracks, and even scrap, and hidden cracks can affect the safety of subsequent use. At the same time, it has extremely high requirements for cutting accuracy and equipment stability, and traditional processes are difficult to balance quality and consistency.
Customer requirements:
The customer is engaged in high-end glass processing and has high requirements for 3mm high borosilicate glass irregular cutting. It requires one-time molding, no broken edges or cracks, and reduces secondary processing; However, the materials are hard and brittle, and the yield of traditional processes is unstable, requiring high-precision and high stability automation solutions to meet the needs of mass production.
Solution:
Chuangkeda's "Infrared Picosecond Laser Glass Cutting Integrated Machine" uses a high-energy density picosecond laser source, combined with intelligent visual positioning and high-precision motion platform, to achieve non-contact processing with minimal thermal impact and no edge breakage during cutting. During the processing, laser energy is applied to the interior of the glass, forming a flat cross-section through the principle of cold cracking. The cutting edge can be directly assembled without the need for secondary polishing. For complex irregular paths, the equipment can operate accurately according to CAD drawings, ensuring the restoration of curves and angle heights. The cutting accuracy of the whole machine reaches ± 0.01mm, with excellent perpendicularity of the incision, edge breakage ≤ 5 μ m, and support for one-time molding of any shape; Equipped with an automated processing platform, it can achieve synchronous cutting of multiple pieces, significantly improving efficiency and providing a stable and efficient solution for high-end glass precision processing.
