The laser cutting machine focuses the laser, which is emitted from the laser through the optical path system into a high power density laser beam. The laser beam illuminates the surface of the workpiece, which is then brought to its melting or boiling point, while a high-pressure gas coaxial to the beam blows away the molten or vaporized metal. As the beam and the workpiece move relative to each other, slits are eventually formed in the material, resulting in a cut.
Laser cutting process is to replace the traditional mechanical knife with an invisible light beam, which has the characteristics of high precision and fast cutting speed. So, how to choose the right laser cutting machine power in the actual demand?
Thickness
First of all, according to the material to be processed and the thickness of the cut to be selected.
We choose the power according to the actual processing material and the actual cutting thickness. So that we can determine which model to buy. Such as machine power, work area, etc., is a simple pavement for later procurement work. The application of laser cutting machine involves a number of industries. Such as sheet metal processing, metal processing, advertising, technology, medical equipment, etc.
Smoothness
Secondly, according to the smoothness of the cutting surface to choose.
Whether the laser cutting surface burrs, mainly related to the cutting thickness and the gas used. 3mm or less cutting without burrs. Nitrogen is the best gas, oxygen is second and air is the worst. Metal laser cutting machine burr minimum or no burr, the cutting surface is very smooth, the speed is relatively high, the material deformation is relatively small.
Core components
Selection of core components for laser cutting.
Laser and laser head using imported or domestic. Imported lasers generally use more IPG, domestic lasers generally use RICO. Also pay attention to other parts of the laser cutting, such as whether the motor is imported servo motor, guide, bed, etc., because they affect the cutting accuracy of the machine to a certain extent.
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 2000W laser cutting machine will be able to meet production needs. If the production volume is large, worry about 2000W efficiency is not as high power laser cutting machine. The best choice is to buy a high-power laser cutting machine, which will help metal processing manufacturers in cost control and efficiency improvement.
