How does Manhart (Guangdong) CNC Machine Tool Co., Ltd. choose appropriate parameters based on different material types and characteristics?

When selecting laser cutting parameters, it is necessary to fully consider different material types and characteristics. Here are some key steps and considerations:
Firstly, understanding the physical and chemical properties of materials is crucial. Different materials, such as metal, non-metal, composite materials, etc., have different absorption, reflection, and thermal conductivity properties for lasers. Therefore, it is necessary to adjust parameters such as laser power, cutting speed, frequency, etc. based on the characteristics of the material to achieve the best cutting effect.
Secondly, the thickness of the material is also an important consideration factor. Thicker materials may require higher laser power and slower cutting speeds to ensure complete cutting and prevent overheating or deformation. On the contrary, thinner materials may require lower power and faster speed to avoid excessive ablation or damage.
In addition, the adjustment of focus position and focal length is also crucial. The correct focus position can ensure that the laser beam is effectively focused on the material surface, improving cutting accuracy and quality. The adjustment of focal length needs to be based on the thickness and properties of the material to obtain the best cutting depth and edge quality.
The selection of gas type and flow rate also needs to be based on the type of material and cutting requirements. Different materials may require different types and flow rates of auxiliary gases to remove molten materials and dust from the cutting area and improve cutting efficiency.
Finally, the selection of spot diameter also affects the precision and flatness of the cutting line. Usually, the smaller the spot diameter, the higher the cutting quality, but it also increases cutting time and power consumption. Therefore, it is necessary to choose a reasonable spot diameter while ensuring cutting quality.
In summary, selecting appropriate laser cutting parameters requires comprehensive consideration of multiple factors such as material type, characteristics, thickness, and cutting requirements. Through continuous experimentation and optimization, the most suitable parameter combination for the current task can be found, achieving efficient and high-quality cutting.
