Maximum cutting thickness range
The maximum cutting thickness of a laser cutting machine varies depending on factors such as material type, laser power, cutting speed, auxiliary gas, and equipment quality. Generally speaking, for common metal materials such as carbon steel, stainless steel, aluminum plate, and copper plate, the maximum cutting thickness is roughly as follows:
Carbon steel: The maximum cutting thickness can reach 6mm to 20mm, depending on the laser power and cutting conditions.
Stainless steel: The maximum cutting thickness is usually between 3mm and 10mm. Stainless steel is relatively difficult to cut and requires higher laser power and appropriate cutting speed.
Aluminum plate: The maximum cutting thickness is generally between 2mm and 8mm. Aluminum plate has a higher reflectivity to laser, so a higher laser energy density is required when cutting.
Copper plate: The maximum cutting thickness is similar to that of aluminum plate, also between 2mm and 8mm.
Factors affecting cutting thickness
Laser power: Laser power is a key factor affecting cutting thickness. The higher the power, the greater the energy density of the laser beam, and the greater the thickness of the material that can be cut. Therefore, when choosing a laser cutting machine, it is necessary to select the appropriate laser power according to the actual cutting needs.
Material type: Different types of materials have different absorption and reflectivity of lasers, so their cutting thickness is also different. For example, metal materials such as carbon steel and stainless steel have a higher absorption rate of lasers, so the cutting thickness is relatively large; while non-metallic materials such as plastics and wood have a lower absorption rate of lasers and a relatively small cutting thickness.
Cutting speed: The cutting speed will also affect the cutting thickness. Generally speaking, the faster the cutting speed, the shorter the action time of the laser beam and the material, and the smaller the thickness of the material that can be cut. However, too fast a cutting speed will lead to a decrease in the quality of the cutting surface, so a balance needs to be struck between speed and quality.
Auxiliary gas: During the laser cutting process, the auxiliary gas can play a role in cooling, blowing off slag and protecting the cutting surface. Choosing the appropriate auxiliary gas type and pressure can improve the cutting quality and efficiency, thereby increasing the cutting thickness to a certain extent.
Equipment quality and maintenance: The quality and daily maintenance of the laser cutting machine will also affect its cutting ability. High-quality equipment has better stability and precision, which can ensure the smooth progress of the cutting process. At the same time, regular maintenance and care of the equipment can extend its service life and keep it in optimal cutting condition.
