How does the laser cutting speed of Manhart (Guangdong) CNC Machine Tool Co., Ltd. affect cutting quality?

Laser cutting speed has a significant impact on cutting quality. The following are several key aspects of how laser cutting speed affects cutting quality:
1. Cut quality: Increasing the cutting speed appropriately can improve the quality of the cut. When the cutting speed is appropriately increased, the incision will become narrower and the surface of the incision will be smoother. This is because faster cutting speed can reduce the heat affected area, thereby reducing the thermal deformation and melting of the material.
2. Hanging slag and slag formation: When the cutting speed is too fast, the cutting line energy will be lower than the required amount. This will cause the cutting melt to be unable to be blown off quickly, resulting in a large amount of drag and incision slag. Hanging slag will reduce the quality of the incision and increase the difficulty of subsequent treatment. On the contrary, a low cutting speed may also cause the molten material on both sides of the incision to aggregate and solidify at the bottom edge, forming difficult to clean slag.
3. Relationship between cutting depth and speed: There is a balance between cutting speed and cutting depth. When the cutting speed is too fast, insufficient cutting heat input can lead to incomplete cutting of the material, resulting in incomplete cutting. This belongs to incomplete cutting and can lead to a decrease in the quality of the incision. And too low a cutting speed can cause the cutting process to become slow, reducing production efficiency.
4. Heat affected zone: Cutting speed also affects the heat affected zone of the material. Faster cutting speed can reduce the size of the heat affected area, thereby reducing the thermal deformation and potential residual stress of the material. This is very important for applications that require high precision and low thermal impact.
In summary, laser cutting speed is one of the key factors affecting cutting quality. In practical operation, it is necessary to choose the appropriate cutting speed based on the type, thickness, and cutting requirements of the material to achieve the best cutting quality and production efficiency.
