As one of the most popular material processing methods at present, laser cutting has a wide range of applications, and has been fully used in many industries such as automobile manufacturing, hardware processing, tableware and kitchen utensils, clothing leather, advertising decoration, and aerospace.
This article will show you the basics of laser cutting, such as: operation, advantages, applications, etc.
Laser Processing Processing Method:
The way of laser cutting is that the laser beam irradiates the surface of the workpiece. Through the conversion between electro-optical and thermal energy, the temperature of the beam irradiation area rises rapidly, and the material is melted and gasified to form holes. As the beam moves, the holes are connected to gradually form lines. Different from traditional cutting, laser cutting is a non-contact thermal processing, and the processing medium is light, so the corresponding knowledge points are also quite different.
Advantages of Laser Cutting:
High precision
Positioning accuracy 0.05mm, repeat positioning accuracy 0.02 mm
Good Cutting Quality
Non-contact cutting, the cutting edge is less affected by heat, there is basically no thermal deformation of the workpiece, and the edge collapse formed during punching and shearing of the material is completely avoided, and the cutting seam generally does not require secondary processing.
High Speed
The cutting speed can reach 10m/min, and the maximum positioning speed can reach 70m/min, which is much faster than wire cutting.
Narrow Kerf
The laser beam is focused into a small light spot, so that the focal point reaches a high power density, and the material is quickly heated to the degree of gasification, and evaporates to form holes. As the beam moves linearly relative to the material, the holes are continuously formed into narrow slits.
Save Material
Using computer programming, products with different shapes can be cut into the whole board material to maximize the utilization rate of materials.
Generally speaking, the thickness limit values of various materials cut by different laser cutting machine powers are as follows: (For reference only, the actual cutting capacity is also related to various factors such as cutting machine quality, cutting environment, auxiliary gas, cutting speed, etc.)
