What is the working principle of laser cutting machine?

Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, so that the irradiated material quickly melts, vaporizes, ablates or reaches the ignition point, and blows out the molten material by the high-speed airflow coaxial with the beam. A thermal cutting method for cutting the workpiece by moving the light spot irradiation position through the numerical control mechanical system.

Is the laser cutting machine dangerous to operate?

Laser cutting is a very environmentally friendly cutting method, generally speaking, there is 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 operation method, it will also cause personal injury to the user or damage to the machine.

1. Beware of flammable materials when using the machine. Certain materials are not allowed to be cut on a laser cutting machine, including foam core materials, any PVC materials, highly reflective materials, etc.

2. During the working process of the machine, it is forbidden for the operator to leave without authorization to avoid unnecessary losses.

3. Do not stare at the laser processing operation. It is prohibited to observe laser light through binoculars, microscope, magnifying glass, etc.

4. Do not store explosive or flammable materials in the laser processing area.

What are the factors that affect the accuracy of laser cutting machines?

There are many factors that affect the accuracy of laser cutting, and some are determined by the equipment itself, such as the accuracy of the mechanical system, the degree of vibration of the worktable, the quality of the laser beam, the influence of auxiliary gas and nozzles, etc. Some are inherent factors of the material, such as the physical and chemical properties of the material, the reflectivity of the material, etc.; There are also some factors that are selected according to the specific processing objects and user quality requirements, and corresponding adjustments are made to determine related parameters, such as output power, focus position, cutting speed, and auxiliary gas.

How does the laser cutting machine find the focus?

Since the laser power density has a great influence on the cutting speed, the choice of focus position is particularly important. The spot size after the laser beam is focused is proportional to the focal length of the lens. There are three simple methods to determine the cutting focus in the industrial field:

1. Printing method: The cutting head is moved from top to bottom, and laser beam printing is performed on the plastic plate, with the smallest printing diameter as the focus.

2. Inclined plate method: Use a plastic plate placed obliquely at an angle to the vertical axis to pull it horizontally to find the smallest point of the laser beam as the focus.

SIEME are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

3. Blue spark method: remove the nozzle, blow the air, hit the pulse laser on the stainless steel plate, make the cutting head move from top to bottom, until the largest blue spark is the focus.

At present, many manufacturers' machines have realized automatic focusing. With the automatic focusing function, the processing efficiency of the laser cutting machine can be significantly improved: the perforation time of thick plates is greatly reduced; when processing workpieces of different materials and thicknesses, the machine can automatically quickly adjust the focus to the most suitable position.

What types of lasers are there and what are the differences between them?

Lasers currently used in laser processing and manufacturing mainly include CO2 lasers, YAG lasers, and fiber lasers. Among them, high-power CO2 lasers and YAG lasers are widely used in precision processing; The fiber laser based on the fiber position has obvious advantages in reducing the threshold, the oscillation wavelength range, and the wavelength adjustable performance, and has become an emerging technology in the current laser field.

What is the cutting thickness of the laser cutting machine?

At present, the cutting thickness of the Oree laser cutting machine can reach up to 50mm. Compared with other cutting methods, it has obvious advantages for cutting materials with a thickness of less than 20mm.

What are the application areas of laser cutting machines?

Laser cutting machine has the advantages of wide cutting range, high cutting speed, narrow cutting seam, good cutting quality, small heat affected zone, flexible processing, etc. It is widely used in automobile manufacturing, kitchenware industry, sheet metal processing, advertising industry, machinery manufacturing, case cabinet, elevator manufacturing, fitness equipment and other industries.

Well I got the laser cutter in last week, but finally got a chance to finish setting it up and play around with it tonight. ...laser cutter / engraver, it is not bad. Attaching an image of some of the things I messed around with tonight, yeah I just used my name, I know boringI was just testing lol
