RFH 20w nanosecond high power UV laser solves the difficulty of cutting glass
The characteristics of glass are well known to be hard and brittle, so cutting glass has always been a difficult task in industrial processing.
Although it is difficult to process, because glass is basically non-conductive, it is suitable for electrodes. Taking advantage of this feature, many electrode glass tubes came into being.
In traditional glass processing, the most common is "diamond tool", or a relatively new alloy material grinding wheel, no matter which one, the principle is the same, that is to use a higher hardness than glass tip to cut.
This "hard-to-hard" cutting method is most commonly used in glass processing. The diamond tip or alloy grinding wheel is used to scratch the surface of the glass. Because of the higher hardness, a crack will be generated, and the glass can be easily cut along the crack.
This traditional method of cutting glass has been around for a long time, but in many years of processing, we have also found many fatal disadvantages, which greatly affect the processing accuracy and scope of application.
Traditional cut glass has three major disadvantages:
1. The cutting precision is not high, and the edges are prone to burrs.
2. It is easy to produce micro-cracks and reduce the overall hardness.
3. The scope of application is narrow, and the processing of glass tubes is difficult.
In addition to the above three disadvantages, traditional processing also has problems such as unstable quality control and low processing efficiency. As a result, a new processing method is urgently needed, and the laser naturally comes to the front.
Since the laser is a "non-contact" processing method, there will be no micro-cracks during processing, and the edges are smooth and sharp, which can be applied to various shapes of glass.
Among all the lasers, the most suitable one is definitely the ultraviolet laser (cold light), but it needs a high-power ultraviolet laser of more than 10W. High-power laser has the characteristics of fast processing speed and high processing accuracy, which meets the requirements of large-scale precision processing.
The RFH 20W high-power UV laser can easily cut the "electrode glass tube", and the 8mm diameter glass tube is cut by rotating, with no burr on the edge and high processing accuracy.
