The laser cutting machine is to focus the laser light emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, the material will eventually form a slit, so as to achieve the purpose of cutting.
Laser cutting processing is to replace the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to the cutting pattern, automatic typesetting, saving material, smooth cutting, and low processing cost. It will gradually improve or replace it. Traditional metal cutting process equipment.
So, how to choose the right laser cutting machine power in actual demand?
High power laser cutting machine
Precautions for choosing the right laser cutting machine power:
1. Choose according to the material to be processed and the cutting thickness:
The power size is selected according to the actual material to be processed and the thickness of the cutting, so that the model of the equipment to be purchased and the processing width can be determined, and it is a simple pavement for the later procurement work. The application field of laser cutting machine involves many industries such as sheet metal processing, metal processing, advertising, craftsmanship, medical equipment and so on.
2. Choose according to the smooth cutting surface:
Whether the cutting surface of laser cutting has burrs or not is mainly determined by the cutting thickness and the gas used. There is no burr for cutting below 3mm. Nitrogen is the best gas, followed by oxygen, and air is the worst. The metal laser cutting machine has the least or no burrs, the cutting surface is very smooth, the speed is relatively high, and the material deformation is relatively small.
3. Selection of core parts of laser cutting:
Lasers and laser heads are imported or domestic. Imported lasers generally use more IPGs, and domestic ones generally use Raycus. At the same time, pay attention to other parts of laser cutting, such as whether the motor is imported servo Motor, guide rail, bed, etc., because they affect the cutting accuracy of the machine to a certain extent. One thing that needs special attention is the cooling system of the laser cutting machine-the cooling cabinet. Many companies directly use household air conditioners for cooling. In fact, everyone knows that the effect is very bad. The best way is to use industrial air conditioners, dedicated for special machines. , In order to achieve the best results.
4. Power selection:
For example, most factories cut metal sheets below 6mm, so there is no need to buy a high-power laser cutting machine. A 1000W laser cutting machine can meet production needs. If the production volume is large, you are worried that the 1000W efficiency is not as good as the high-power laser cutting machine. The best choice is to buy two or more small and medium-power laser cutting machines, which will help manufacturers in controlling costs and improving efficiency.
