In industries where precision, cleanliness, and material integrity are non-negotiable, the demand for advanced ceramic processing is growing rapidly. Silicon oxide (SiO₂) ceramics—known for their excellent thermal stability, electrical insulation, and mechanical strength—are widely used in microelectronics, aerospace, energy, and medical devices. However, their high hardness and brittleness make them notoriously difficult to machine using conventional tools.
To meet this challenge, Han’s Laser offers advanced ceramic laser cutting solutions specifically designed for high-performance materials like silicon oxide. In this article, we explore the application of laser cutting machines for 5mm-thick SiO₂ ceramic processing, highlighting the technological advantages and real-world capabilities of the equipment.
Why Laser Cutting for Silicon Oxide Ceramics?
Silicon oxide ceramics are resistant to heat and chemical corrosion, but these same properties make them hard to cut or drill without microcracking or chipping. Laser cutting—especially with short-pulse, high-energy lasers—offers a non-contact, low-stress alternative to mechanical processing.
The benefits of laser cutting for SiO₂ ceramics include:
- Minimal thermal damage
- Clean, burr-free edges
- No tool wear
- High precision and repeatability
- Complex contour capability
