Optical fiber laser cutting machine is more and more widely used in aerospace, medical equipment, precision instruments and other industries for parts processing because of its high-precision laser cutting processing. How can optical fiber laser cutting machine achieve fine cutting?
As we all know, laser is known as the brightest light, the most accurate ruler and the fastest light. Through technical means, the laser can gather quite high energy on a very small unit area, so that metal and other materials can melt or vaporize rapidly, thus playing the role of cutting.
The focused beam can usually reach about 0.1mm, which is like a very delicate knife, of course, much more sophisticated than the “big axe”. At the same time, due to the large energy density of processing, the time acting on the material is very short, so that the workpiece has small heat affected zone, small thermal deformation, and small thermal stress. In addition, the laser is non mechanical contact processing, which has no mechanical stress on the workpiece, and is suitable for precision processing.
Secondly, a stable machine tool system is the basis for maintaining the accuracy of the optical fiber laser cutting machine. Through rigorous mechanical design, precision welding, stress relief and other operations, the optical fiber laser cutting machine is smooth and stable in operation, and can maintain long-term accuracy.
Finally, the fiber laser cutting machine can achieve precision cutting thanks to its high-precision transmission structure, including gear rack, servo motor, reducer, etc.
To sum up, the optical fiber laser cutting machine can achieve fine cutting.
