As described in the previous section, the type of laser suitable for a laser cutting application is largely determined by the material being cut. Lasers are produced as either pulsed beams or continuous wave beams. The suitability of each depends on the properties of the material being cut and the requirements of the laser cutting applications. Pulsed beams are produced as short bursts of power output, while continuous wave beams are produced as continuous, high power output.
Generally a slower process, ablative laser cutting is used to make partial cuts that don’t pass through the workpiece from top to bottom . In contrast, fusion cutting fires lasers in continuous waves or longer pulses, and therefore can only be used to cut all the way through the workpiece. Waterjet cutting is a fabrication process which employs pressurized water—as well as abrasives, such as garnet or aluminum oxide—to cut and form material into custom shapes and designs. While there is less risk of mechanical distortion with laser cutting, waterjet cutting offers a lower risk of thermal distortion. Compared to laser cutting, waterjet cutting also generates more noise and more waste—i.e., used water and abrasive mixtures—which require cleanup and disposal, increasing operation costs. When laser cutting material via the reactive melt shearing process, an active (i.e., chemically reactive) assist gas—typically oxygen—is employed to accelerate the cutting process.
They lend an elegantly rustic touch to place settings and double as take-home gifts for guests. If you want to make a statement from the minute your wedding guests open the invitation, laser engrave the envelopes. It’s made from 3mm acrylic; use clear for the top panel to see the engraving, then choose your fave color for the sides and bottom. If you love old arcade games (who doesn’t?!), then don’t miss a little piece of electronics enclosures heaven with this throwback game console powered by Raspberry Pi.
Even components which are formed three-dimensionally such as heat protection sheets for exhaust gas systems may be precisely cut with a laser. Any explicit consent from you to process your personal data can be revoked at any time by unchecking the following checkbox. Please note that up until revocation, the legal validity of consent-based processing remains unaffected. Fifth, the quality of equipment and the stability of use are also very important metrics. Now the product development cycle is short, the update is faster and faster, the product diversity, sample trial production, mass production is more.
The laser optics and CNC are used to direct the material or the laser beam generated. A commercial laser for cutting materials uses a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish. This is super important in the world of laser cutting because all sorts of heat and gas are produced. Because the laser is so highly localized, you won’t even feel it when you stand next to the machine. But to the material that’s being worked on it will feel like a furnace under the laser spot!
Economical exploitation of materials and very clean cutting edges on certain materials that do not require reworking are two other positive aspects of this cutting process. Disadvantages include the high up-front costs for the equipment and ongoing costs for power and gas. These popular laser cutting machines with this caliber of functionality are very useful in all types of mechanical industries. CNC laser cutter technology has evolved through the years and become a powerful platform for metal cutting as well as other kinds of raw material cutting.
A highly recommended piece of kit for those of you who are looking to try something new and take up a fun hobby. It just doesn’t have the necessary power and degrees of freedom to work in 3D. There’s nothing wrong with that as long as you know what you’re buying when you part with your cash. If you expect to be able to do everything the more comprehensive models can do, then you’ll be disappointed. If you keep your expectations realistic, then I think you’ll be quite contented with your purchase. This may seem like a fairly unusual addition given the power, but I thought why not give it a shot?
The interaction between a focused laser beam and workpiece forms the basis of laser cutting. In order for this process to be carried out reliably and precisely, numerous components and additional equipment are used on and around the laser beam, which will be illustrated in the following graphic. Laser engraving machine is mainly used for processing non-metallic materials such as acrylic, wood, rubber and some thin metal plates. Fiber laser is a kind of laser that is mainly used to cut, mark, and engrave various types of metals. Choosing the manufacturers who have fiber laser cutting service is versatile for various customers.
If the decision is made to bring laser cutting in-house, you may be put in a position where you need to justify why the investment needs to be made. The costs associated with subcontracting out the laser cutting are just the starting point for the justification. How much more productive will the manufacturing process be with in-house laser cutting? From an expense standpoint, not only do you have the cost of the laser cutting machine, you have labor and consumable costs, such as laser cutting assist gas. The revolutionary Vertical Laser XL is our largest laser engraver. The machine features an 80W CO2 laser tube and power supply to provide faster laser cutting ability.
Since cost is important, mechanical cutting is more expensive to buy and run. If a seam is detected by the software, the machine will rotate the tube to mitigate any potential problems. The best machines will use a sensing system equipped with two cameras and light sources to look inside and outside the tube. The unloading process is completely automatic to reduce processing and feeding times. Some manufacturers will order custom tubes to ensure there is the least amount of excess during production. Avoid scrap by having tubes designed specifically for the materials you are using.
One of the great things about laser cut products is the precise, consistent cutting of fine details. The intricate design of these wood bookmarks look like the imagery came right out of a fairy tale. Everyone loves refrigerator magnets; that’s why businesses use them as promotional tools.
Laser cutting can produce extremely small cuts (down to 0.011”) at tolerances of +/- 0.002”. The team at Union Machine has worked with businesses in sectors such as aerospace, mining, construction, medical, energy, and other industries that require close tolerances, complex geometries, or precision cutting. In lieu of servo control axes, the stages can be controlled manually if off-axis processing is not required. The YZ stage is ball screw driven incorporating brushless servo motors with accuracies of +/- 5 microns for the Y axis and +/- 20 micron for the Z axis. The programmable Y and Z axis motion produces parallel wall features while off axis cutting. The tube periphery cutting is controlled by a linear motor X axis and a brushless direct drive servo motor for the rotary axis.

The beam is only about 3/4 of an inch in diameter as it travels from the laser resonator, which creates the beam, through the machine’s beam path. It may be bounced in different directions by a number of mirrors, or “beam benders”, before it is finally focused onto the plate. The focused laser beam goes through the bore of a nozzle right before it hits the plate. Also flowing through that nozzle bore is a compressed gas, such as Oxygen or Nitrogen.
