Many customers in the first choice of laser cutting machine equipment, will encounter many problems, do not know how to choose, now let sunshanlaser cutting machine manufacturers to explain to you.
What is CO2 laser cutting machine
Non-metal laser marking field common solid laser marking machine and gas laser marking machine (CO2 laser cutting machine) non-metal laser cutting machine generally rely on laser power driven laser tube light, through the refraction of several reflectors, so that the light transmission to the laser head, and then the laser head installed by the focusing mirror will converge the light into a point.
This point can reach a very high temperature, so the material is instantly sublimated into gas. This point can reach a very high temperature, which will instantly sublimate the material into gas, which is sucked away by the extractor fan, to achieve the purpose of cutting; generally, a laser cutting machine using the laser tube filled with the main gas is CO2, so this laser tube becomes a CO2 laser tube and the use of this laser tube laser cutting machine called CO2 laser cutting machine.
What is laser cutting system
Laser cutting system is a class of large and medium-sized manufacturing enterprises; these enterprises produce many products that need to feed and cut material and have strong economic and technical strength.
Another type of unit is the processing station (foreign called Job Shop); processing station is dedicated to external laser processing business, no leading products of their own. Its existence, on the one hand, to meet the needs of some small and medium-sized processing; on the one hand, at the initial stage of the promotion of the application of laser cutting technology to play a role in the promotion of demonstration
Who invented laser cutting machine
Fiber laser cutting of metals has become an extremely common process in many fields, widely used in manufacturing plants, and the subtleties of laser surgery can even be called art. However, despite its widespread use, laser cutting is still a relatively new technology compared to all cutting processes. Let’s take a short look at the history of using laser cutting.
The first lasers
The first actual working lasers date back to 1960 but were not very versatile then and therefore described as “solutions in search of a use.”
However, the laser beam’s capabilities were obvious. Its ability to emit only a single, strong, narrow wavelength beam meant that it had potential uses in dozens of industries.
The discovery of the laser beam has caused a stir in the scientific community and even the public. People were unsure just how far this technology could go. Discussions of the laser beam’s “death ray” were regularly featured on the front pages of national newspapers.
When was the laser invented
The laser beam has long been a fantasy, immortalized like a death ray by the popular Star Wars franchise. Still, the scientific and manufacturing communities began to see practical uses for the laser beam soon after its discovery in 1960.
One of the first processes discovered was the cutting process, which uses a laser beam to cut through the material. Scientists invented several types of lasers – the gas laser cutting process using a carbon dioxide mixture was first invented by electrical engineer Kumar Patel in 1964 at Bell Labs in New Jersey. This was also the same year that the crystal laser process was developed, which was also invented at Bell Labs in 1964 by another engineer named J. E. Geusic.
What is the use of laser cutting machine
1、Laser vapor cutting.
The temperature rises rapidly using a high energy density laser beam to heat the workpiece. It reaches the boiling point of the material in a very short period, and the material begins to vaporize, forming vapors. These vapors are ejected at a large rate, and while the vapors are ejected, a cut is formed in the material. The heat of vaporization of the material is generally very large, so a high power and power density are required for laser vapor cutting. Laser vaporization cutting is mostly used for the cutting of very thin metal materials and non-metallic materials.
2, laser melting cutting.
Laser melting cutting, with laser heating to melt the metal material, and then through the nozzle coaxial with the beam spray non-oxidizing gas, relying on the strong pressure of the gas to make the liquid metal discharge, forming a kerf. Laser melting cutting does not require complete vaporization of the metal and requires only one-tenth of the energy required for vapor cutting. Laser melting is mainly used to cut some materials or reactive metals that are not easily oxidized, such as stainless steel, titanium, aluminum, and its alloys.
3, laser oxygen cutting.
The laser oxygen cutting principle is similar to oxyacetylene cutting. It uses the laser as a preheating heat source, with oxygen and other reactive gases as the cutting gas. The gas is blown out on the one hand with the cutting metal, and the oxidation reaction occurs, releasing a large amount of oxidation heat; on the other hand, the molten oxide and molten material are blown out of the reaction area, forming a kerf in the metal.
Since the oxidation reaction generates a large amount of heat during the cutting process, the energy required for laser oxygen cutting is only half of that for melt cutting. The cutting speed is far greater than that for laser vapor cutting and melt cutting. Laser oxygen cutting is mainly used for carbon steel, titanium steel, heat-treated steel, and other easily oxidized metal materials.
4, laser scribing and controlled fracture.
Laser scribing uses high energy density laser scanning on the surface of brittle materials so that the material is heated to evaporate a small groove and then apply a certain pressure. The brittle material will crack along the small groove. Controlled fracture uses the vertical temperature distribution created when the laser scribes the groove to create local thermal stress in the brittle material, causing the material to break along the small groove.
What can a laser cutting machine do
Metal fiber laser cutting machines can carry out almost all the required cutting, both to replace the traditional cutting machine and to carry out high-precision, ultra-small pieces, high hardness materials, and so on.
Fiber metal laser cutting machine can be applied to metal sheet processing, advertising signage word production, high and low voltage electrical cabinet production, mechanical parts, kitchenware, steam degree car, machinery, metal crafts, saw blades, electric know ware parts, eye industry, spring pieces, circuit boards, electric kettles, medical microelectronics, hardware, knife and measuring instruments and other industries.
CNC laser cutting machine is a large object; you must choose good quality.
How long is the life of CNC laser machine
As metal laser cutting machine manufacturers, after-sales staff often receive user responses to various after-sales issues, such as customers asking, “a metal laser cutting machine life how long?” According to the design standards, CNC laser equipment, for example, the service life of the equipment can reach more than ten years because most core laser equipment life of up to 100,000 hours or more; many customers of the fundamental cause of equipment failure is that the operator does not operate the metal laser cutting machine equipment according to the requirements of the standard, or not regular maintenance of equipment and lead to the. Over time, it is bound to gradually shorten the life of the metal laser cutting machine while also increasing its after-sales costs.
How much does a textile laser cutting machine cost
About the fabric laser cutting machine, after my understanding is very high. Because the fabric laser cutting machine is a technology-based machine, so its price is higher. The general market for ordinary fabric laser cutting machine in the $ 300 or so. But the model is different, the price of fabric laser cutting machine is also different, you need to determine the specific price at the time of purchase.
How long does it take for laser cutting
Often operating the machine to learn for about 7 days, simple processing operations can be learned, and the machine encounters problems that need to be solved. After at least half a year of learning, you need to be able to CAD, design their processing drawings, read processing drawings, and have no CAD base; then, you can go to self-learning online learning corresponding courses.
“Laser cutting” technology needs to learn laser principles, materials, and knowledge of thermal processing.
