1、What are the characteristics of thin glass materials? What fields are mainly applicated in?

Glass is a very fragile material, but because it looks crystal clear and beautiful, it makes more and more modern products adopt it as a processing material to make glass. Due to the fact that  glass materials are very difficult to process and the impact of external forces, mechanical stress and thermal influence can make the glass break, so the processing of glass materials require a very high degree of precision, especially some thin glass will even be tested for stress before it is used. Glass products are widely used in applications such as architecture, automobiles, photovoltaic energy and containers, and have the characteristics of transparency and high strength. In the actual use, it is inevitable that glass drilling is required.

2、How can laser technology improve the efficiency of glass drilling?

To drill on the glass, especially thin glass, the traditional mechanical drilling method can cause a significant drop in glass yield, so glass manufacturers are almost always looking for laser drilling solutions. The high peak power and high energy density laser can instantly vaporize the glass, and then with motion control can cut the desired hole at the specified location. Glass laser hole cutting has the advantages of small taper, high precision, small chipping, no consumables, maintenance-free, etc. It is also easy to integrate for automated production. For thin glass materials, currently commonly used laser precision perforation laser processing methods: laser precision perforation is to reduce the spot diameter to the micron level, so as to obtain a high laser power density, almost any material can be implemented in the laser perforation. It is characterized by the ability to drill on glass in hard, brittle or soft materials with small apertures, fast processing speed and high efficiency.

Green Light Glass Laser Drilling Machine

Tianhong Laser recommends Green Light Glass Laser Drilling Machine（TH-G-LD-30）adopts imported lasers from Europe and the United States, with 3D dynamic focus oscilloscope scanning system, processing speed can reach up to 40mm /s, cutting chipping is less than or equal to 70um. It can be applied to a variety of glass materials cutting holes, such as ordinary household glass, photovoltaic glass, single-sided frosted glass, glass containers and other light-transmitting glass on the round hole, square hole, waist-shaped hole, shaped hole cutting, etc., and the shape of the hole design is flexible, hole wall clean.Basically there is no dust residue, no damage with high efficiency. At the same time, through the cutting test of the same aperture, the higher the power, the faster the efficiency, 200W efficiency is 2.5 times than that of 80W, and the effect is basically the same. Glass laser drilling effect and laser continuous drilling stability test are shown below.

In addition, as to the glass UV laser drilling machine, non-contact punching processing is also a good laser processing method, which can solve the problem of high scrap rate of drill hole on glass. Directly  set size and location on the computer when needing to determine how big the hole drilled on the glass. High-density laser beam instantly hit the glass without any external damage, and will not let the glass material change. UV laser can also be called cold light, because it is specifically for a variety of fragile products for perforation processing, its wavelength is 355nm, the spot can be as small as 0.001mm, so when the cold light processing glass its temperature will be lower, and the laser pulse width is narrow and beam speed can instantly penetrate to complete the perforation process. Glass UV laser drilling machine can process ultra-micro-hole, spot quality is good, the hole is very round, and each workpiece aperture size, position is consistent, the quality of the processed effect is very good.They are the reasons why laser equipment is widely used. And UV laser drilling speed is very fast, a micro hole can be completed within a few seconds and can be processed in a short time batch of glass drilling. I hope the above sharing can help you, if you have glass cutting, drilling needs welcome to consult at any time!
