Answers to several problems of laser cutting machine-Cathy

How to find the focal position of laser cutting machine ?

As laser power density has a great influence on the cutting speed, so the selection of the focal position is particularly important. Also the spot size of the laser beam is proportional to the length of the lens. There are three simple ways to find the cutting focus position in the industrial files:

1.Pulse method. Let laser beam print on a plastic sheet,moving the laser head from top to bottom,checking all holes and the smallest diameter is the focus.

2.Slant plate method. Using a slant plate under the vertical axis, moving it horizontally and looking for the laser beam at the minimum focus.

3.Blue Spark. Remove the nozzle, blow the air, pulse on stainless steel plate, move the laser head from top to bottom, until find the blue spark as the focus.

At present, many manufacturers’ machines have automatic focus. Automatic focus can significantly improve the laser cutting machine’ efficiency, piercing time on thick plate is significantly reduced; The machine can adjust automatically to find the focus position based on different materials and thickness.

How many types of laser machine have? What’s the difference between them?

Currently, lasers for laser processing manufacturing mainly include CO2 laser, YAG laser, fiber laser,etc. And among them, high-power CO2 laser and YAG laser have more applications in the confidentiality processing. Also Fiber lasers with fiber-optic matrix have obvious advantages in reducing the threshold, the range of the oscillation wavelength and the tunability of the wavelength, it has become the emerging technology in the field of the laser industry.

What’s the cutting thickness of laser cutting machine?

And at present, cutting thickness of laser cutting machine is less than 25mm, compared with other cutting methods, laser cutting machine has a clear advantage in cutting material less than 20mm with high accuracy requirement.

What’s the application range of laser cutting machines?

Laser cutting machine has high speed, narrow width, good cutting quality, small heat affecting area and good flexible processing. So it is popular in automobile manufacturing. Such as kitchen industry, sheet metal processing, advertising industry, machinery manufacturing, cabinet processing, elevator manufacturing, fitness equipment and other industries.
