Laser Cutting and Drilling of Glass/Materials

Laser Processing and Automation for Micro Materials

Corning Laser Technologies is on the forefront of laser innovation, offering laser systems that have a distinct advantage over conventional glass cutting processes. Corning offers laser glass processing systems with the ability to cut Corning® Gorilla® Glass, chemically strengthened glass as well as un-strengthened glass and other brittle materials.

The flexible machine platforms serve a wide range of emerging applications, which require precise and flexible glass processing technologies. Designed for substrate sizes up to an edge length of 2.5m, combined with the best beam delivery technology from fixed optics via scanner systems to flying optics, enables flexible adaption to individual customer requirements.

In-house process development and tailored solutions for full automation, round out the product portfolio, providing a one-stop-shopping at Corning.

Corning’s laser processing systems are designed for continuous operation and combine +20 years of experience in laser precision machining with Corning’s unique material science knowledge.

Advanced Laser Process

Conventional laser cutting is based on rapid heating processes, leading to vaporization and material removal. This method tends to create micro-cracks, chip-outs and a rough surface finish, which makes time consuming and costly subsequent grinding and polishing steps necessary, leading to low production yields.

Using specially tuned lasers to cut glass by disassociation rather than ablation, the Corning laser glass cutting technology provides numerous benefits:

Smooth Edges – The ‘as-cut’ edge roughness may significantly reduce or in some cases even eliminate post-processing and thus process time and cost.
High Break Strength – The ‘as-cut’ edge demonstrates superior break strength over other laser and conventional cutting processes as measured by 4 point bend tests.
Multi-Layer Stacks – The systems enable cutting of assembled functional multi-layer stacks with and without air gaps, where cutting depths can be adjusted.
