In the fields of precision electronics, optical components, and high-end experimental equipment, borosilicate glass with high aluminum content is widely used in functional structural components and precision window parts due to its excellent high-temperature resistance, chemical corrosion resistance, and high mechanical strength. However, this type of glass material has high hardness and brittleness, making it particularly prone to edge chipping, microcracks, and dimensional deviations during circular cutting under 1mm thickness conditions, which imposes extremely high requirements on machining equipment and process stability.
Customer requirements:
The customer requires mass cutting of multiple high-consistency circular structures on 1mm high-alumina borosilicate glass for subsequent precision assembly. The customer explicitly specifies: the cutting edges must be smooth and flat, free from obvious chipping and hidden cracks, with high dimensional consistency of the circular structures. Additionally, the cutting process must avoid creating a heat-affected zone on the glass to ensure the long-term reliability of the finished product.
Solution:
The "Infrared Picosecond Laser Glass Cutting Machine" from ChongkeDa utilizes a high-energy-density picosecond laser source, an intelligent visual positioning system, and a high-precision motion platform to achieve non-contact, low-thermal-impact, edge-free cutting. During the cutting process, the laser energy is uniformly applied to the glass interior, forming clean sections through the cold cracking principle, allowing direct assembly without secondary grinding. For complex irregular paths, the machine's intelligent control system can precisely operate according to CAD drawings, ensuring every arc and angle perfectly matches the design. With a cutting precision of up to ±0.01mm, excellent verticality, and edge chipping ≤5μm, the machine supports arbitrary shape cutting, enabling one-time completion for circular, square, curved, or irregular contours. Additionally, the integrated automated processing platform enables synchronous cutting of multiple glass pieces, significantly enhancing production efficiency and providing a high-quality, high-efficiency solution for precision glass processing.
