How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. choose the appropriate parameters of a dual platform laser cutting machine based on the characteristics of the cutting materials?

Choosing the appropriate parameters for a dual platform laser cutting machine based on the characteristics of the cutting material is an important step. Here are some suggestions:
Firstly, it is necessary to have a deep understanding of the properties of the cutting material, including its thickness, hardness, melting point, thermal conductivity, and optical properties. These properties will directly affect the absorption rate, reflectivity, and thermal conductivity during laser cutting, thereby determining cutting speed and incision quality.
Secondly, based on the properties of the material, choose the appropriate laser power. Different materials have different absorption capabilities for lasers, so it is necessary to determine the required laser power based on the material’s absorption rate. Thicker materials or high melting point materials may require higher laser power to achieve effective cutting.
At the same time, adjust the cutting speed to adapt to the characteristics of the material. Cutting too fast may result in rough or incomplete cuts, while cutting too slowly may reduce production efficiency. Therefore, it is necessary to find the optimal cutting speed based on the hardness and thermal conductivity of the material to achieve high-quality cutting.
In addition, the type and flow rate of gas are also important parameters. Select the appropriate gas type and flow rate based on the type of material and cutting requirements. For example, cutting stainless steel may require the use of nitrogen as an auxiliary gas, while cutting aluminum alloys may require the use of oxygen. At the same time, adjust the gas flow rate to ensure stability and cutting quality during the cutting process.
In addition to the above parameters, optical parameters such as focus position and spot diameter also need to be considered. The adjustment of the focus position can ensure that the laser beam forms the optimal energy density on the material surface, while the size of the spot diameter affects the precision and cutting speed of the cutting line. Therefore, it is necessary to finely adjust these parameters based on the characteristics of the material and cutting requirements.
Finally, in the actual operation process, it is recommended to conduct small-scale experimental cutting, observe and test the cutting effect, and gradually adjust the parameters to achieve the best cutting quality and speed.
In summary, selecting appropriate parameters for a dual platform laser cutting machine based on the characteristics of the cutting material requires comprehensive consideration of multiple factors such as material properties, laser power, cutting speed, gas type and flow rate, and optical parameters. By finely adjusting these parameters, high-quality cutting effects can be achieved.
