Laser cutting is the most advanced cutting process in the world today. Compared with other cutting processes such as flame cutting, plasma cutting, high-pressure water jet cutting, etc., it has a huge advantage. Its processing objects include almost all metal and non-metal materials. It can cut 3D solid parts with complicated shapes for materials with high hardness, high brittleness and high melting point, which is also the advantage of CNC laser cutting technology.
High laser power and good cut quality: The laser beam is a heat source with high energy density. Cutting low-carbon steel, the width of the cut can be less than 0.1 ～ 0.2mm, the cutting surface roughness is only a dozen microns, and the accuracy of cutting parts can reach ± 0.05mm. Therefore, laser-cut parts are often used directly without machining because of the good cutting quality.
The input heat is small, the material deformation is small, and the material performance is affected: Due to the extremely high power density of the laser beam, the heat affected area is very small during cutting. Generally, it is only 0.01 to 0.1 for thin plates. influences.
Good processing flexibility: Laser cutting does not require any tools and molds. The laser is transmitted through optical lenses. The cutting process can be fully numerically controlled. Under computer control, it can directly realize the flexibility of plate and shell parts in any shape in two or three dimensions. Processing, especially suitable for the processing of multi-variety and small-volume sheet metal parts at the stage of new product development, can save expensive mold design and manufacturing costs, and greatly shorten the production cycle.
High cutting efficiency: Take a 1mm thick carbon steel plate as an example, the cutting speed can reach 40m / min, and the high efficiency makes the processing cost of a single piece reduce geometrically, even lower than traditional processing methods.
Laser cutting is a non-contact optical thermal processing, known as a universal tool that never wears: the laser beam can be moved on the surface of the part to achieve the cutting function. Tightly arrange or nest, so that the raw materials are fully used. Because it is non-contact processing, the workpiece does not deform after processing.
