There are three simple methods to determine the cutting focus in the industrial field:
1. Printing method: Move the cutting head from top to bottom and perform laser beam printing on the length of the plastic plate, with the smallest printing diameter as the focal point& nbsp;
3. Blue Spark Method: Remove the nozzle, blow air, and apply a pulsed laser onto the stainless steel plate, causing the cutting head to move from top to bottom until the maximum blue spark is the focal point& nbsp;
2. Oblique plate method: Use a plastic plate placed at an angle to the vertical axis to pull it horizontally and find the minimum point of the laser beam as the focal point& nbsp;
3. Do not stare at laser processing operations& nbsp;
Is it dangerous to operate a laser cutting machine?
Laser cutting is an environmentally friendly cutting method that generally poses no harm to the body& nbsp;
What are the application ranges of laser cutting machines?
Laser cutting machines are widely used in industries such as automobile manufacturing, kitchenware, sheet metal processing, advertising, machinery manufacturing, chassis and cabinets, elevator manufacturing, fitness equipment materials, etc. due to their advantages of wide cutting range, high cutting speed, narrow cutting seam, good cutting quality, small heat affected zone, and flexible processing& nbsp;
What is the cutting thickness of the laser cutting machine?
At present, the thickness cut by laser cutting machines generally does not exceed 25mm. Compared with other cutting methods, it has significant advantages for cutting materials with precise dimensions below 20mm. However, if not operated accurately and safely, it can also cause personal injury to the user or damage to the machine& nbsp;
Currently, many manufacturers' machines have achieved automatic focusing. High power CO2 lasers and YAG lasers are widely used in secret processing; Fiber lasers based on fiber substrates have significant advantages in reducing threshold, oscillation wavelength range, and wavelength tunability, and have become an emerging technology in the field of lasers. With the automatic focusing function, the processing efficiency of laser cutting machines can be significantly improved: the perforation time of thick plates is greatly reduced; Processing workpieces of different materials and thicknesses, the machine can automatically adjust the focus quickly to the most suitable position& nbsp;
Be careful of flammable materials when using the machine& nbsp;
What are the types of lasers and what are their differences?
At present, the lasers used for laser processing and manufacturing mainly include CO2 lasers, YAG lasers, and fiber lasers. Compared to ion cutting and oxygen cutting, laser cutting produces less dust, weaker illumination, and lower noise& nbsp;
What are the factors that affect the accuracy of laser cutting machines?
There are many factors that affect the accuracy of laser cutting, some of which are determined by the equipment itself, such as mechanical system accuracy, worktable shock level, laser beam quality, and the influence of auxiliary gases and nozzles; Some are inherent factors of materials, such as their physical and chemical properties, reflectivity, etc; There are also some factors that are selected based on detailed processing objects and user quality requirements, and corresponding adjustments are made to determine relevant parameters, such as output power, focal position, cutting speed, and auxiliary gas& nbsp;
During the operation of the machine, it is prohibited for the operator to leave without authorization to avoid unnecessary losses. The size of the spot after laser beam extraction is directly proportional to the focal length of the lens. What is the working principle of laser cutting machine?
Laser cutting is a thermal cutting method that uses a focused high-power density laser beam to irradiate a workpiece, causing the material at the irradiated area to quickly melt, vaporize, burn, or reach the ignition point. At the same time, the molten material is blown out by a high-speed airflow coaxial with the beam, and the laser spot irradiation position is moved by a CNC mechanical system to achieve cutting of the workpiece& nbsp;
4. Do not store explosive or flammable materials in the laser processing area. It is prohibited to observe lasers through binoculars, microscopes, magnifying glasses, etc. Some materials are not allowed to be cut on the laser cutting machine, including foam core materials, any PVC materials, high reflective materials, etc& nbsp;
How to find the focus of a laser cutting machine?
Because the laser power density has a significant impact on cutting speed, the selection of the focal position is particularly important.
