Do you know anything about laser cutters?

The first thing you need to do is to find out what you need to do to get the best results. With the development of laser cutting technology, the application fields of laser cutting are more and more extensive, and more and more suitable materials are available. But how much do you know about the problems that laser cutting machines often encounter? How much do you know about the following tips?

1. How long have laser cutters been around ?

Although it sounds like a modern cutting process, laser cutting has actually existed for more than half a century. In the mid-1960s, researchers from the Western Electrical Engineering Research Center made the world's first laser cutting machine for drilling holes in diamonds.

2. How does a laser cutter work  ?

Laser cutting is the use of focused high power density laser beam irradiation of the workpiece, so that the irradiated place of the material rapidly melting, vaporisation, ablation or to reach the ignition point, and at the same time borrowed and beam coaxial high-speed airflow blowing out of the molten material, through the numerical control of the mechanical system to move the spot irradiation position so as to achieve the cutting of the workpiece of a thermal cutting method.

3. Is it dangerous to operate the laser cutting machine?

Laser cutting is a very environmentally friendly cutting method, generally speaking, no harm to the body. Compared with ion cutting and oxygen cutting, laser cutting produces less dust, weak light and low noise. However, if you do not follow the correct procedures and methods of operation, there are some dangerous situations.

4. What are the factors affecting the accuracy of laser cutting machine?

There are many factors that affect the precision of laser cutting, some of which are determined by the equipment itself, such as the precision of mechanical system, the vibration degree of worktable, the quality of laser beam, the influence of auxiliary gas and nozzle, etc. Some are inherent to the material, such as the physical and chemical property properties of the material, the reflectivity of the material, etc. , while others are selected based on the specific processing object and the quality required by the user to make appropriate adjustments. Determine the relevant parameters, such as output power, focus position, cutting speed and auxiliary gas.

5. What are the types of lasers and what are their differences?

The main types of lasers used in laser manufacturing are CO2 lasers, YAG lasers and fibre lasers. Among them, high-power CO2 lasers and YAG lasers are more used in classified processing; fibre lasers with fibre optic bit substrate, in the lowering of the threshold, oscillating wavelength range, wavelength tunable performance and other aspects of the obvious advantages, has become an emerging technology in the field of laser.

6. What is the thickness of laser cutting machine cutting?

At present, the cutting thickness of laser cutting machine generally not more than 50 mm, compared with other cutting methods for cutting 20 mm below the requirements of precise size of the material has obvious advantages.

7. What are the applications of laser cutting machine?

The laser cutting machine has the advantages of wide cutting range, high cutting speed, narrow slit, good cutting quality, small heat-affected zone and flexible processing, widely used in automobile manufacturing, kitchen supplies, sheet metal processing, advertising industry, machinery manufacturing, cabinet, elevator manufacturing, fitness equipment and other industries. However, the general laser cutting machine is divided into metal cutting and non-metal cutting two, there are mixed cutting, metal non-metal can, but not recommended. Different laser cutting machine manufacturers produce different types of laser cutting machine, the focus is also different.

In the future, fibre laser cutting machine will gradually replace the traditional processing technology, become more efficient, fast processing method. Pentium Intelligent focus on the development and manufacture of various laser equipment, bevel laser cutting equipment won the China Laser Golden Yew Bonus Award, 20KW laser cutting equipment to obtain the first set of national major technical equipment products, 30KW laser cutting equipment to obtain the title of the first set of major equipment international products. 2021 the end of the year, by the end of the Pentium independent research and development of the 40KW laser cutting equipment has been successfully developed and put into use. Mastering the core technology of high power laser cutting machine, leading the global high power laser equipment, so that China‘s intellectual property, so that the world praise!
