Industry Information

Laser Cutting

Laser cutting is a low-distortion hot cutting process that most commonly uses a CO2 laser for the cutting of material, usually metal or sheet metal. Thus, a laser is sometimes also called a metal laser.

"Laser" is an acronym for Light Amplification by Stimulated Emission of Radiation; it emanates a light that contains a decent amount of electromagnetic radiation. This extremely focused radiation of a wavelength does not dissipate like conventional light beams. A laser beam is way stronger and denser than any other type of light that we have known so far. The beam emission device can be programmed and the intensity of the laser beam can be manipulated according to the requirements of the application.

Applications

In general terms, laser cutting is a value-added service that helps you to cut, slice or chip, melt, and vaporize a wide variety of materials. Various industrial processes would remain incomplete without this technology.

Many manufacturing industries depend on laser cutting's microscopic tolerances and precision accuracy to fabricate small, intricate parts. Such industries include: microtechnology, electronics, medical device, automotive manufacturing, aerospace, military and defense, communications, plumbing and HVAC.

Products Produced

Laser cutting is used for products and parts including: catheters, hypo-tubes, gas flow orifices, filtering devices, nozzles, solar cells, gaskets and circuit boards for aerospace, cell phone parts, computer microchips, transducers, water piping systems, refrigeration systems, and many types of military and communication devices.

History

As far as technology goes, lasers are a fairly recent invention; while their foundation stretches back to the theories of Einstein in the early 1900s, the first laser was built just a little over fifty years ago, in 1960, by Theodore H. Mainman. The first cut laser cut material on an industrial scale in 1965. Made at the Western Electric Engineering Research Center, it was used to drill holes into diamond dies. Two years later, in Great Britain, engineers developed the first laser-assisted oxygen jet cutting systems. They were used in sheet metal fabrication and cutting.

In the early 1970s, this metal laser cut technology was adapted for custom laser cut services, such as aerospace titanium cut services. Also, in the 70s, engineers used CO2 lasers to cut non-metal materials, like textiles. At that time, the CO2 cut laser was too weak to cut through metal.

Since then, laser cutting technology has grown by leaps and bounds. More recent improvements include: power efficiency increases, cost reductions, new wavelength bands, and more. Today, laser cutting can be used in surgery, weapons technology, and intricate machining. We predict that, as science and engineering continue to march forward, so will laser cutting services.

Process Details

To control a laser cutter process, engineers and technicians use laser optics and a computerized or computer-controlled device to cast a programmed and well-controlled laser beam onto the material which has to be cut. CNC laser systems use CAD designs to input all the necessary machining details into a computer program that then fully directs the laser cutting process, requiring a minimal staff to simply oversee the production and make sure the machines are well maintained.

To cut the programmed pattern, either the beam or the workpiece can move. As one or the other does this, the focused beam melts material in a localized area. To direct the light of the laser, manufacturers use mirrors or fiber optics to point the beam to lens, through which it focuses. They program the laser cutter to stimulate a laser material via electrical discharges or lamps within a closed container. As it is stimulated, the beam is reflected internally against a partial mirror. This continues until it has enough energy to escape as a monochromatic, coherent stream of light.

Assist gas such as nitrogen or carbon dioxide is used in conjunction with laser cutting to prepare newly cut surfaces for painting or corrosion resistance. When done with a tube laser, the gas is placed inside the laser tube. An example of the gas assist laser technique is CO2 laser cutting, which is considered the most powerful wave laser technique. In addition, for large and critical applications, manufacturers will couple a speed control system with the emission device. This way, the laser is controlled and considered safe for various industrial applications.

Design

When designing your custom laser cut product, manufacturers take a variety of factors into consideration. These include: required tolerances, required thicknesses, best material, best laser cut system, the sharpness and cleanliness of the laser cutter, and the position of the nozzle or head.

The sharpness and cleanliness of a laser cutter:

    By checking that the lens, or cutter, is adequately cleaned, laser cutting services try to make certain that their process machine is ready to perform the material cutting task. Most importantly, they have to make sure that their lens or cutter is in good and working condition.

The position of the nozzle or head:

    To test out whether the nozzle is in the center, the laser cutting service provider takes a thin tape and broadcasts a low-intensity laser beam on it. Then, they check if the hole created by the beam is at the desired place. This particular test helps them in determining that their laser drilling machine is ready to use.

    Manufacturers offer a wide range of custom laser cut services. To give you the tolerances and part thickness that you want, they can tweak elements of their laser system, including cut speed, assist gas, CNC laser cut programming inputs, the heat-affected zone, etc.

Machinery Used

To create the high-quality results for which precision laser cutters are known, manufacturers rely on a variety of different machinery, particularly laser types. Some frequently used laser cut machine varieties include: fiber lasers, high-power lasers and metal lasers.

Fiber Laser

    A fiber laser is a laser that uses an optical fiber treated with rare earth elements like thulium, holmium, erbium, or ytterbium. Fiber lasers are great because they do not have moving parts, meaning that their maintenance requirements and operating costs are quite low.

High-Power Laser

    As their name pointedly suggests, high-power lasers are machinery used to cut stronger materials, such as mild steel, carbon steel, stainless steel or titanium. The high laser power label can be attached to many different laser types, including fiber laser and solid-state laser varieties.

Metal Laser

    "Metal laser" is the name assigned to any laser machine that is designed for the cutting of metal materials specifically. Most often, these are metals like: mild steel, stainless steel, titanium, and/or scribing metals.

Variations and Similar Processes

Other common laser marking processes include laser engraving, laser drilling and waterjet cutting. Many manufacturers of laser cut products are able to offer custom laser cutting, which is used when the design is too complex or intricate to cut by hand.

Laser Engraving

    Laser engraving, also known as laser etching, is an engraving process that uses laser technology in order to etch marks into a surface. The best way to laser engrave something is using a laser engraver. This type of engrave machine is usually CNC-controlled, using inputs from a CAD computer program and a human operator to determine the speed, spread and intensity of the laser beam. The big difference between a laser cutter and engraver is the that the laser engrave machine, instead of melting surfaces, either fractures or vaporizes them.

Laser Drilling

    To create precise holes with tight tolerances, manufacturers go with laser drilling. As its name suggests, this process uses a laser beam to make holes.

Waterjet Cutting

    This cut service creates and machines shapes using highly pressurized streams of water. When manufacturers waterjet cut materials instead of using laser cut technology, they save energy and resources. However, this method can only be used on some materials; it cannot be used on super hard materials like diamonds, nor can it be used on breakage-prone materials like some glass compositions.

Benefits

Using lasers to cut and machine metal has distinct advantages over conventional cutting processes like thermal machining, mechanical machining, arc welding, EDM and flame cutting. Let's go over some of those advantages below.

Quality

    First, laser cutting systems have very high levels of beam control and motion stability; these allow them to produce products with an extreme edge quality. In addition, laser-cut parts have nearly zero edge deformation and zero roll-off or edge factor, leaving very little burring on part edges.

Accuracy

    Laser cutting services offer neither quite as much cost efficiency as cold-water jet cutting, nor the completely burr-free finished edging of water jet cutting processes. Nevertheless, laser cutting is capable of creating tighter accuracies on a smaller scale than any other type of metal cutting process.

Turnaround Time

    Laser cutting is faster than conventional tool-making techniques and has a quicker parts turnaround time, regardless of complexity. This is because the service allows for easy accommodation of design changes.

Safety

    Although laser cutting systems release a potentially dangerous CO2-based laser beam, if protocol is properly followed, they do not pose any threat of damage or human injuries during operation. Furthermore, because they are controlled by CNC machining, laser cutters require few technicians on the floor.

    Of course, the machines do need to be handled with extra care, especially when you are working on materials that are prone to catch fire. Also, any operators that go near the laser need to wear proper protective eye gear.

Versatility

    Many different kinds of laser cutting services are available, all of which make highly efficient use of materials, creating little waste.

Ease of Maintenance

    Laser cutting and engraving systems require little maintenance. You can easily maintain your premises and materials by simply ensuring proper ventilation in the working area and making sure that no flammable gases or chemicals (droplets) are there in the atmosphere. For this, we recommend a robust and efficient air filtration system installed at your place.

Energy Efficiency

    Laser cutter, laser cutter engraver, and laser drilling machines do not consume much energy. Instead, they are rather energy efficient, and save you money on your power bill.

Things to Consider

Laser cutting does have a few disadvantages, most of which involve the drawbacks of hot cutting. The material being cut gets very hot, so in narrow areas thermal expansion and warping may be a problem. Distortion and oxidation can be caused by oxygen, which is sometimes used as an assist gas, because it puts stress into the cut edge of some materials; this is typically a problem in dense hole patterns. Lasers also require large amounts of energy, making them costlier to run. Lasers are not very effective on metals such as aluminum and copper alloys due to their ability to reflect light as well as absorb and conduct heat, nor can laser cutting be used on crystal, glass or any other non-metals.

Despite these drawbacks, laser cutting is an excellent service to consider. To learn about the possibilities for your application, contact a reputable laser cut service provider.

Browse their respective websites, pick out a few that have the capabilities you require, and then reach out to them. Talk over your specifications with them; make sure to voice all questions and concerns. Make your final decision based on who you believe will provide you with the best possible customer service and products.




Laser Cutting Types

  • CNC laser cutting is a process that uses an intense laser beam to cut part shapes out of sheet material. The parts remain flat because the heat distortion is minimal.
  • CO2 laser cutting is a process that uses carbon dioxide as the main lasing medium. CO2 lasers use a mixture of gases-such as helium and nitrogen, with CO2 being the most predominant-to create a cut quality similar to that of milled edges of mild steels and can operate in continuous wave (CW) or pulses.
  • Custom laser cutting is always done with CNC machining programs that are custom programed to design unique designs exactly like the buyer desires.
  • Evaporative laser cutting is the process of ablating target materials, typically low vaporization temperature and low thermal conduction materials, through direct vaporization.
  • Excimer laser cutting is a process that uses the noble gas compounds for lasing. Excimer lasers generate light in ultraviolet to near-ultraviolet spectra.
  • Gas laser cutting is a process in which gas is used as the activating agent.
  • Nitrogen cutting or inert gas cutting provides cut edges covered with melted and resolidified metal comprised of the same metal mixture of the material. Thus it has the same resistance to corrosion and is useful for food processing facilities, chemical plants and sign production.
  • Laser cutters perform all the services and all of the processes that cut metal or other materials with lasers to create precision products.
  • Laser drilling is the process of creating a hole in material with a laser beam.
  • Laser engraving uses lasers to etch into a surface.
  • Laser etching is the process of marking the material without cutting all the way through using reduced power.
  • Laser machining is the removal of material brought about by laser material interaction. Laser machining is a term that includes laser drilling, laser cutting, laser grooving, laser marking or laser scribing.
  • Laser marking is a process in which material is indelibly marked at very fast speeds (milliseconds per character). Laser marking is flexible, programmable and environmentally clean.
  • Laser metal cutting involves lasers cutting the most common material used to produce machining products: metal.
  • Laser micromachining is a process used to create extreme detail and to cut very precise components that require close tolerances.
  • Laser welding is the process of using a laser beam to connect two or more pieces of metal together by melting the areas to be joined and allowing them to resolidify.
  • Liquid laser cutting is the process in which large organic dye molecules are used as the active lasing medium.
  • Melt shearing, also known as "fusion," is the laser cutting process that creates a melt, which a gas jet blows out of the melt zone, typically with air. The resultant cut edge is of high quality but is covered with microscopic ripples.
  • Moving optics laser cutting is a process in which mirrors are used to reflect the laser beam to the cutting head while the work piece material remains fixed.
  • Multi-axis laser cutting is a kind of laser cutting utilizing multiple axes instead of one. The advantage of multi-axis laser cutting is the capability of cutting three-dimensional shapes, while the disadvantages are the higher expense over flat bed cutting, longer set up times and increased safety hazards.
  • Oxygen assist cutting is a process in which the oxygen does the actual cutting, and the laser beam maintains the reaction.
  • Pulsed laser cutting is a cutting process that uses single or train pulses, as opposed to continuous wave lasers. These pulses supply greater power at shorter intervals.
  • Semiconductor laser cutting is a process utilizing semiconductor materials as the active medium.
  • Solid state laser cutting is a process in which the active medium of the laser (typically not semiconductor lasers) is in a solid state.
