Revolutionizing Laser Glass Drilling: How the Green Laser Technology is Changing the Game
The glass drilling technology has been revolutionized by the development of the green laser. This has enabled the production of laser machines which can quickly and precisely drill holes and shapes into glass. Customers who are considering investing in this technology need to calculate the takt time of their produced goods. The speed of drilling depends on several factors such as glass thickness, the shape of the area to be drilled, and whether the shape fits into the scanner field of 50×50 mm. Additionally, factors such as glass color and coating can also affect the speed of drilling. By understanding these factors, customers can determine the feasibility of investing in this technology. In this article, we will delve into the world of the green laser technology and explore how it can revolutionize the glass drilling process.
The Basic Fundamentals of the Drilling Process
Understanding the basics of the drilling process is crucial for predicting what is technically possible and for troubleshooting issues. So here is a short explanation.
The process involves focusing a laser beam onto the surface of the glass, which then penetrates through to the bottom where the ablation process begins. When drilling a hole, the laser beam follows a spiraling upward path, gradually ablating the glass until the center piece falls out and a hole is formed. This process is highly controlled and precise, ensuring accuracy in the final product. The area which is being ablated consists of 0.2 – 0.3 mm.
The Drilling Speed
To assess the viability of a new investment, companies need to determine the takt time for their manufactured product. Discussions around our laser technology typically focus on creating holes or shapes in glass. Refer to the schedule below to grasp the process of calculating the takt time:
Our scanner operates within a 50×50 mm field, where the laser demonstrates competitive drilling times. As an example, let’s consider the white goods industry, where we may need to drill an 11 mm hole in 4 mm thick glass.
To calculate the takt time, we divide the circumference of the hole by the drilling speed. Referring to the table above, we find that the drilling speed for a circle in 4 mm thick glass is 9 seconds.
Using this information, the equation becomes:
(11 mm x 3.14(pi))/9 = 3.837 seconds.
This drilling speed is generally considered acceptable in the white goods industry.
Our machines can perform shape cutting on any geometry within the scan field, with only a slight reduction in speed. However, if the shape extends beyond the scan field, our cutting speed decreases significantly due to the need for a stitching method.
With this method, the laser must resume cutting at the exact spot where it stopped at the 50 mm edge of the scan field, resulting in a loss of cutting speed.
We hope that we could give you a good impression of the drilling speed of our green laser technology. With this fundamental information you should be able to create an opinion regarding your existing setup and if our technology could be a viable application for your next investment.
