As a precision processing method, laser cutting can cut almost all materials, including two-dimensional or three-dimensional cutting of thin metal plates. So, what are the common application areas of laser cutting? What are the advantages?
Analysis of common application fields and advantages of laser cutting

1. Metal cutting in common application areas of laser cutting
Laser cutting not only works on a large number of metals, but is also a universal tool among industries. Laser cutting processing can get cleaner, smoother and tighter cuts than mechanical processing. Like mechanical processing, it can also be programmed and guided by a computer, which means that the laser cutting machine can automatically manufacture a large number of metal parts for industries such as automobiles and computers. Usually, strange shapes like car frames or hydroformed parts require laser cutting, as do many parts in the aerospace industry, and the results are usually better than plasma cutting.
2. Reflective metal cutting in common application areas of laser cutting
Because reflective metals reflect the backlight shining on them, this raises concerns when irradiating them with high-power laser beams. If the metal reflects the laser, it will self-destruct. The solution to this problem is to use fiber laser cutting. Using this technology, fiber optic cables transmit the laser beam to the metal. The reflected light will not damage the optical cable. Metals such as aluminum, silver, copper, and gold are all reflective and are essential in the production of automobiles and semiconductors.
3. The common application field of laser cutting is medical scientific cutting
Laser cutting processing also plays an important role in the medical industry. In the medical industry, extremely high precision and strict dimensional tolerances are essential. Due to the medical industry’s demand for high-volume production, this technology meets their needs because it can replicate designs, both accurately and quickly. Many types of medical devices have their origins in laser cutting, from cardiovascular and orthopedic devices to surgical implant components. With laser cutting, these devices can be manufactured at a faster rate without sacrificing accuracy.
In the field of automobile manufacturing, the cutting technology of space curves such as car roof windows has been widely used. German Volkswagen uses a laser with a power of 500W to cut complex-shaped body sheets and various curved parts. In the aerospace field, laser cutting technology is mainly used for cutting special aviation materials, such as titanium alloys, aluminum alloys, nickel alloys, chromium alloys, stainless steel, beryllium oxide, composite materials, plastics, ceramics, and quartz. The aerospace parts processed by laser cutting include engine flame tube, titanium alloy thin-walled casing, aircraft frame, titanium alloy skin, wing stringer, tail wall panel, helicopter main rotor, space shuttle ceramic insulation tile, etc.
Laser cutting technology also has a wide range of applications in the field of non-metallic materials. Not only can cut materials with high hardness and brittleness, such as silicon nitride, ceramics, quartz, etc.; it can also cut and process flexible materials, such as cloth, paper, plastic plates, rubber, etc., such as using laser to cut clothing, which can save clothing 10 %～12%, increase the efficacy by more than 3 times.
