Fiber laser cutting is limited by the output power of the laser generator the volume of the machine equipment. Only medium small thickness plates pipe fittings can be cut by fiber laser cutting. With the increase of the thickness of products, the laser cutting rate is significantly reduced.
The cost of optical fiber equipment is high the investment of one-time project is large.
Application scope of fiber laser cutting
Most of the fiber laser cutting is controlled by the program flow of CNC machine tool made into laser cutting intelligent robot. As a high-precision production processing method, fiber laser cutting can basically cut all raw materials, including two-dimensional laser cutting of thin metal sheet.
In the automotive industry, the laser cutting technology of interior space curve such as car roof window has been widely used. VW uses a laser generator with output power of 500W to cut complicated car body sheet metal various inclined surface parts. In the aerospace industry, the key technology of optical fiber laser cutting is laser cutting of raw materials of special airlines, such as titanium, aluminum alloy profiles, nickel base alloy, cobalt alloy, stainless steel plate, air oxidation wrinkle, polymer materials, plastics, porcelain calcite. The aerospace components produced by fiber laser cutting include diesel engine flame tube, titanium thin-walled casing, airport structure, titanium skin, aircraft wing stringer, automobile tail wing wall panel, helicopter main rotor, aerospace spacecraft porcelain insulation tile, etc.
Optical fiber laser cutting forming technology is widely used in non-metallic material industry. It can only cut raw materials with high strength ductility, such as silicon nitride, porcelain calcite, but also produce process soft raw materials, such as fabric, paper shape, plastic plate, vulcanized rubber, etc. if the clothing is cut by laser, the fabric can be saved by 10% ~ 12%, the effect of improvement is more than 3 times.
