What is the laser cutting machine?
Laser cutting machine is a device that uses high energy to generate heat to cut materials. This article will focus on the specific discussion of glass laser cutting machine. I hope everyone can have a general understanding of the working principle, application scope, advantages and disadvantages of glass laser cutting machine.
Glass laser cutting machine equipment is mainly composed of laser, optical system, workbench, cooling device, fire head, clamp and control panel. The working principle is that the laser emits high-energy laser, which is focused by the optical system and irradiated to the surface of the glass product to be cut. The high temperature causes a certain depth of scratches on the glass surface. Then the glass is automatically and neatly cut after high temperature heating and cooling.
When working, first put the glass tube or glass pot on the fixture and fix it to keep it stable; set parameters according to the needs of the finished glass, including the speed of the fixture and workbench, laser power, the distance between the laser emitter and the product (that is, the focusing distance of the laser, to ensure that the laser beam accurately cuts the glass at high temperature and avoids the generation of debris at the edge of the glass), the amount of oxygen and natural gas, and the speed of the receiving tray, etc., to ensure that each parameter is accurate; start the machine, the glass product is automatically brought to the cutting area, first cut a scratch by the laser, and then moved to the heating area for heating until it is completely disconnected, and the clamp automatically clamps off the excess part to complete the cutting; then turn off the machine and check the cutting effect. The whole process can be completed manually through the control panel or the automatic system can be set to complete it in one go.
It can be seen that the glass cutting machine has higher cutting accuracy (can reach micron accuracy); the shapes that can be cut are diverse, breaking the traditional straight cutting process; the cut is smooth, and the glass after laser cutting has basically no burrs and cracks; the cutting efficiency is high, and the laser irradiation time is only a few seconds to complete the scratch positioning; but at the same time, there are some difficulties for users, such as high cost. Compared with ordinary fire-melting cutting process machinery and equipment, the high-end cost of laser cutting technology is several thousand yuan higher; the temperature is not easy to control, and the glass irradiated by the laser beam is easy to explode. The temperature control is more stringent than other cutting methods; but with the development of technology, these problems are gradually weakened. More and more glass laser cutting machines and equipment are used in decoration, packaging, glass sprinkler manufacturing, etc., which greatly improves production efficiency and quality.
When cutting, we should pay attention to the following points:
1. Wear protective equipment, including gloves and goggles, to avoid high temperature burns and glass fragments flying and stabbing the skin:
2. Regularly check the machine equipment, especially the parts of such machines cannot be ignored;
3. Before shutting down, all air valves must be closed
4. After work, clean up the glass fragments on the workbench to avoid accidental injuries
In short, as a precision tool of modern industry, laser cutting machine plays an increasingly important role in various industries with its high precision, high speed, non-contact cutting and wide applicability.
