Creating a laser cutting work needs to import laser cut files into the CNC laser cutting machine. Manufacturers according to their demands design the laser cut files, and the laser cut files determine the quality of laser cutter projects. As the relative position of the beam and the workpiece moves, the material will eventually form a slit. Laser cutting processing is to replace the traditional mechanical knife with an invisible beam. It has the characteristics of high precision, fast cutting, not limited to cutting patterns.
Realistically there is no one right or wrong engraving machine on the list. You may need something with serious cutting power while others might want something as a hobby device, or to help their up and coming Etsy store. There’s no shortage of engraving and cutting machines on the market. And with such an expansive price point it’s tricky to pick one over others. After all, you can get some impressive devices at the top of the price point.
CNC Laser Cutting has many advantages over Flame, Plasma, and Waterjet Cutting methods. As the Laser’s heat application is tightly focused, it requires less power and the material’s heat-affected zone is reduced. Many high-end industrial Laser Cutting machines are accurate to 10 micrometers and have a repeatability of 5 micrometers. CNC Lasers can affordably cut and etch a wide variety of materials, even the non-metallic materials that typically cannot be cut by Flame or Plasma processes. CO₂ and YAG Lasers are similar in construction but are used differently. C0₂ Lasers with lower power levels are used for engraving, while ones with higher power levels are used in industrial applications for welding and cutting because of their reasonably low price.
With precision control from CNC integration, our laser machines can make precise cuts at speeds much faster than other mechanical cutting equipment. Laser cutting machines are widely used in industrial manufacturing, school education, small business, home business, small shop, home shop, hobbyist, craftsman. Those looking to buy a used laser cutting machine should ensure the device is equipped with the latest laser technology. A CNC laser should be powerful enough to processing panel thicknesses of 40 mm for steel, 50 mm for stainless steel and 25 mm for aluminium.
The independent two heads laser cutting system is perfectly combined with the smart vision system, and further optimized in the requirements of printed graphics processing. A variety of industries will use the laser cutting method to create quality products. This includes but is not limited to woodworking, aerospace, automotive, electronics, and medical. It might come as a surprise that the word “laser” is actually an acronym for “Light Amplification by Stimulated Emission of Radiation”. The laser is a beam of intense light with a single wavelength or color and a diameter that is less than 1 inch.
Table 3, below, illustrates the suitability of each type of laser previously described for cutting a material. Laser cutting employs a variety of assist gases to aid the cutting process. The cutting process employed and the material being cut determine the type of assist gas—either inert or active—that is most suitable for use. However, it’s better off used as an engraver due to its low power.
Fiber lasers are optimally suited for metal marking by way of annealing, metal engraving and marking thermoplastics. It works with metals, alloys and non-metals alike, even including glass, wood and plastic. Fiber lasers, depending on the power, can be quite versatile and deal with a ton of different materials. While working with thin materials, fiber lasers are the ideal solution.
Cut quality can be affected by raising or lowering the focal point from just above the surface of the plate, at the surface, or just below the surface. The Pulsar NT Series provides the latest developments in machine, CNC and laser resonator technologies. The Pulsar NT Series is designed for the high-volume, short-run production of sheet metal parts, featuring reliable high-speed processing, easy material loading, and automated unloading of multiple parts. The Pulsar series also features AMADA’s advanced cutting technique, CleanCut™. The 3kW, 6kW, and 9kW LCG AJ Series was developed with AMADA’s proven fiber laser technology. This technology helps achieve Process Range Expansion (P.R.E.) by having the ability to process brass, copper and titanium — materials that can be difficult to process with a CO2 laser.
The moving mass is constant, so dynamics are not affected by varying size of the workpiece. Flying optics machines are the fastest type, which is advantageous when cutting thinner workpieces. HACO fiber laser cutting machine with an integrated loading and unloading system.
Laser cutters are often operated two-dimensionally but, in some models, are also suitable for processing 3D items, such as pipes and profiles. Depending on the equipment included in the device, laser cutting also enables the production of three-dimensional openings. Today there are two popular types of laser cutting machines used in precision sheet metal fabrication, C02 and fiber. Fiber lasers boast extremely fast processing speeds and the ability to cut reflective materials which are not able to be processed using a C02 laser.
The market is driven by increasing focus on automating metal cutting process. This latest generation fiber laser facilitates integration into factory automation networks using Ethernet/IP protocol and embedded controller technology. Fiber lasers can be used for a wide variety of applications, from industrial traceability to branding, on materials such as steel, aluminum, plastic, & ceramic. Laser cutting works by directing the output of a laser through optics to cut high-precision patterns out of a variety metals, including steel, titanium, aluminum and copper as well as some plastics and glass. Because of the exceptional level of control, fiber lasers are used in some capacity in a wide array of industries, including aerospace, automotive, battery, electronic, printing, solar, etc. Preco’s PC based machine HMI is a CNC controller designed for laser processing with G-code programming.
