Frequently Asked Questions About Laser Cutting Machine 12

There are three simple ways to determine the focus of cutting in the industry:

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

3. Blue spark method: remove the nozzle, blow 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.

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.

3. Do not stare at the laser processing operation.

Is the laser cutting machine dangerous to manipulate?

Laser cutting is a very environmentally friendly cutting method, generally speaking, there is no harm to the body.

What are the application areas of laser cutting machines?

Laser cutting machine is widely used in automobile manufacturing, kitchenware industry, sheet metal processing, advertising industry, for its advantages of wide cutting range, high cutting speed, narrow cutting seam, good cutting quality, small heat-affected zone, and flexible processing. Machinery manufacturing, chassis cabinets, elevator manufacturing, fitness equipment and other industries.

What is the cutting thickness of the laser cutting machine?

At present, the thickness of laser cutting machine generally does not exceed 25mm. Compared with other cutting methods, it has a significant advantage for cutting materials with precise dimensions below 20mm. However, if you do not follow the correct safety operation method, it will also cause personal injury to the user or damage to the machine.

At present, many manufacturers' machines have realized automatic focusing. Among them, high-power CO2 lasers and YAG lasers are widely used in secret processing; fiber lasers based on optical fiber have significant advantages in reducing thresholds, oscillating wavelength ranges, and wavelength tunable functions, and have become emerging in the current laser field. Technology. 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 different thicknesses, the machine can automatically adjust the focus to the most suitable position quickly.

1. Beware of flammable materials when using the machine.

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

Laser currently used in laser processing and manufacturing mainly includes CO2 laser, YAG laser, and fiber laser. Compared with ion cutting and oxygen cutting, laser cutting produces less dust, weak light and low noise.

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 shock level of the workbench, the quality of the laser beam, the influence of auxiliary gas and nozzles, etc.; some are inherent factors of the material, such as material The physical and chemical properties of the material, the reflectivity of the material, etc.; there are some factors that are selected according to the detailed processing object and user quality requirements, and corresponding adjustments are made to determine the relevant parameters, such as output power, focus position, cutting Speed u200bu200band auxiliary gas, etc.

2. During the working process of the machine, the operator is prohibited from leaving without authorization to avoid unnecessary losses. The spot size after the laser beam will be extracted is proportional to the focal length of the lens. What is the working principle of laser cutting machine?

Laser cutting is the use of 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 at the same time blows out the molten material by the high-speed airflow coaxial with the beam, through the numerical control The mechanical system moves the spot irradiation position to realize a thermal cutting method for cutting the workpiece.

4. Do not store explosive or flammable materials in the laser processing area. It is forbidden to observe laser light through binocular telescope, microscope, magnifying glass, etc. Certain materials are not allowed to be cut on a laser cutting machine, including foam core materials, any PVC materials, highly reflective materials, etc.

How to find the focus of the laser cutting machine?

Because the laser power density has a great influence on the cutting speed, the choice of focus position is particularly important. laser cutter
