A fiber laser cant magically cut cleanly through poor quality material.

Fiber laser cutting quality. Fiber lasers generally have a bpp of 1 to 3 mm mrad which allows the laser to cut very fast in thinner materialsyet the edge quality in the thicker materials deteriorates. An advantage of fiber lasers over other types include light is already coupled into a flexible fiber. Fiber laser cutting is a more recent technology and has grown dramatically in popularity partly due to its superior quality when cutting thinner material. Given its dominance in the sheet metal cutting industry this article focuses on laser fusion cutting. First the impact of focus position adjustment on cutting quality. Is best fiber laser cutting machine cnc laser cutting machine and metal laser cutting machine supplier we has good quality products service from china. Fiber laser cutting machine is a laser cutting method using fiber laser generator as light source. After the laser beam focusing the spot size is proportional to the focal length of the lens. Factory cut chart settings. The fact that the light is already in a fiber allows it to be easily delivered to a movable focusing element which is important for laser cutting welding and folding of metals and polymers. For laser generator with continuous wave output the laser power size and mode will have an important influence on the cutting quality. How to control the fiber laser cutting quality. The two most common types of laser cutting machines are fiber laser and co 2. But the piercing cycle has been susceptible to blowback which is why manipulating the beam often in proprietary ways and the side air jet has been so critical during the pierce cycle. Co 2 lasers generally have a bpp of 8 to 9 mm mrad which allows the laser to cut steel stainless and aluminum with very good edge quality.

The examples of the adjustments made will be similar for any co2 or fiber laser cutting mild steel with o2. The fiber lasers pierce has always been fast. Co 2 lasers use an electromagnetically stimulated gastypically a mixture. Fiber laser is a new type of laser beam developed in the world. Since the laser power density has a great influence on the cutting speed the choice of lens focal length is an important issue. If youd like to learn more about ablative laser cutting check out this article on micron scale manufacturing. In practice the maximum power is often set to obtain the fastest cutting speed to improve the production efficiency or to cut the thicker material. It outputs a high energy density laser beam focuses on the surface of the workpiece melts and evaporates the area illuminated by the ultra fine focus. Fiber lasers vs co 2. In fact fiber laser sales have now outpaced those of co2 but it isnt a catch all solution.
