Introduction To The Principle Of Picosecond Laser Cutting Glass

Traditional glass cutting technology uses diamond or alloy to draw microgrooves on the glass, and external force is applied on both sides of the microgrooves to extend the glass in the thickness direction, forming longitudinal cracks to achieve cutting, which can meet the processing requirements of traditional glass. In the past ten years, the information display industry has promoted the progress of new types of glass, towards the direction of lightness and thinness and excellent damage resistance. Especially with the wide application of hardened glass, the optimization space of traditional cutting technology has begun to narrow. In order to achieve high-precision cutting, it usually needs to increase the extra workload of grinding and polishing, which reduces the production efficiency. The comprehensive performance of internal damage puts forward higher requirements.

Glass laser cutting is an easy-to-control, non-contact, low-pollution technology, which brings great convenience to customers; at the same time, it can ensure the advantages of neat edges, good verticality and low internal damage under high-speed cutting. It is becoming the glass cutting industry New solutions. Especially for high-precision cutting, the picosecond ultrafast laser shows great advantages due to its extremely narrow pulse width. It uses the characteristics of low thermal energy diffusion to complete the material interruption before the heat is transferred to the surrounding materials, which is effective in the cutting of brittle materials Good results.

Laser cutting glass is an innovative technology that has entered a practical stage in the application of cutting touch display glass and mobile phone back glass. Realize the efficient and low-cost cutting of new glass. In the long run, the use of laser cutting glass has obvious advantages, making laser a viable alternative to traditional mechanical cutting for manufacturing in the field of information display.
