Before buying laser cutting equipment, you must know what to search for. Precision, speed, and adaptability are just a few reasons why laser-cutting equipment is gaining popularity across many sectors. Even with this, purchasing the incorrect machine can damage your company's bottom line. With the information provided here, you can buy laser-cutting equipment with confidence. All of your questions about laser cutting will be answered here, from how the technology works to how to determine what you need to install and train to running costs and upkeep. Then, let's dive in and find out everything we can about these laser cutters.
What Is A Laser Cutting Machine?
CNC machines can include laser cutting machines. Computer Numerical Control is an abbreviation for "CNC." The CNC machine gets its moniker because it is programmed using digital blueprints that have been translated into a computer language that details the design's every angle and curve.
After completing a drawing in a 3D modelling programme, the designer needs only transmit the file to the rendering machine. It works similarly to delivering a picture file to a regular printer.
The best aspect is that the laser cutter can reproduce these designs in minutes and make as many components as you require.
How Do Laser Cutting Machines Work?
The following part discusses the many kinds of lasers found in CNC machines. However, the operation of each laser cutter is very similar.
The process begins with a laser source, which generates bright, stable light that can be fine-tuned rapidly and precisely.
Once concentrated, the light can be guided to a pinpoint. The concept at work here is similar to what you experience when you use a magnifying glass and direct sunlight to start a fire. The light can be focused to such a degree that it becomes extremely hot, melting through whatever substance you choose to use as a cutting tool.
Typically, a gantry system is used to support the laser. As a result, the laser can be moved freely along an XY plane. As a result, it can faithfully duplicate complex designs with several curves and angles.
However, not all lasers have the power to cut through metal, and not all can generate the same level of detail.
Different Laser Cutting Machines
CO2, neodymium, and fibre lasers are the three most common types of industrial laser cutters. However, each have their advantages and disadvantages.
Carbon dioxide lasers
The CO2 laser is the most extensively used laser-cutting machine due to its low price. However, fibre laser cutting systems are quickly replacing it with their superior technology.
Carbon dioxide (CO2) and nitrogen gas are contained in a long, vacuum-sealed tube at the centre of a CO2 laser. Electric current passing through this tube stimulates gas molecules, producing bright light.
This light is reflected many times after emerging from the tube. First, the light is focused by reflecting off of mirrors. Next, the light is concentrated to a high temperature by the lens. After that, the laser can use thermal separation to make clean cuts through various materials.
In sheet metal fabrication, CO2 lasers have the advantage over fibre lasers due to the higher quality of their edges, especially on metals thicker than.25 inches.
Fibre Lasers
Fibre lasers are similar to fibre optic lamps in how they operate. One type of light is transmitted via a glass tube coated with another type of glass having altered reflecting characteristics. That makes the light "bounce" down the tube, gaining intensity as it travels.
Because of its unique characteristics, this light is readily absorbed by nonporous surfaces such as metal.
Fibre optics also permit the laser to have a significantly narrower profile. Because of this, these laser-cutting machines can produce very fine details.
This makes low-power fibre lasers perfect for intricate engraving work. In seconds, they can copy a digital image onto metal.
The metal cutting is done using stronger fibre lasers; today's fibre lasers can cut through 2 inches of steel. Our 8KW fibre laser, for instance, can slash through 1.5" of stainless or aluminium and 1" of steel. These machines are huge and costly but are also relatively low-maintenance due to the lack of moving parts that could wear out or need adjusting.
What You Should Think About Before Purchasing A Metal Laser Cutting Machine
Material Considerations
Structural steel, aluminium, stainless steel, copper, titanium, and brass are just some of the metals that can be cut with a laser cutter. Consider the volume of material you go through on a monthly basis as you weigh the benefits of investing in a laser cutter for your business. In addition, consider the thickness of the materials you'll need for your projects. Workbench space and electricity consumption are two further factors to think about.
Features of Lasers
When comparing laser cutters, speed, accuracy, and laser strength relative to your specific material and the thickness of the jobs at hand should all be considered. There is a large selection of laser cutters to choose from, but you should take into account the needs of your workshop when making your selection.
Software
Pay close attention to the machine's interface, software, and features while shopping for a fibre laser cutter. Can a file be imported from my current CAD/CAM programme? Does the software check your imported drawings for errors? This warning is invaluable if you want to ensure your component won't malfunction before you begin running the job. Can tasks be saved for later use? This is a great benefit for factories where consistency is an issue. Is it straightforward for the user to begin a task, track its progress, and mark it as finished? If you want your machinery running at peak efficiency, you need to get to the bottom of these problems.
Capacity for Production
Do you specialise in small-batch manufacturing? Do you need to manufacture a wide variety of components, all for the same project? When selecting a laser cutter for your business, it's important to consider each job's specific needs. Although many machines can complete the task at hand, picking the right one is crucial because it will impact your ability to mass-produce components. For example, determine if a pallet changer might help your metal fabrication facility save time when loading metal sheets. This alone can drastically reduce the time to switch out pallets, sometimes down to just 10 seconds. You can also incorporate other automated material management systems to ensure your fibre laser cutting machine is always active.
Safety
Safety features should rank high on your list of priorities when researching laser-cutting machines. While laser-cutting equipment is incredibly useful in metal workplaces, they require strict safety measures to prevent accidents. Fume extractors are among the most important safety elements and require the right interlocks and sensors. Fumes from the material can build up if there's too much cutting, so getting them out of the way is important. Due to the contained nature of these devices, users should not worry about laser exposure causing any harm to their eyes. When the machine does the cutting, there is less chance of the operator becoming overworked or hurt.
Financial Plan
As mentioned, successful organisations rely on innovation to stay competitive and headed in the correct direction. After figuring out what you need, you can choose a price range. It is feasible to choose a machine that fits both your needs and your budget. However, you should avoid buying an expensive machine that can't do the work you need or has a negative return on investment. Buying solely on price can turn into a trap in this situation. In all likelihood, your business's laser cutter will open up new avenues of profit.
Since the cutting process may be optimised with a laser cutter, fewer people can be employed to do the job. While the job is processing, these operators are available to work on other tasks. In the long run, this reduces your per-unit costs, allowing you to charge more for your products. A laser cutting machine is an excellent investment because it may increase your shop's output by a factor of two and maintain a constant output rate.
Assistance and Maintenance
Despite the durability of fibre laser printers, mechanical failures are still possible. For less serious problems, some modern technologies allow for remote diagnosis and support. Ensure the fibre laser machine you choose is supported by the reseller you buy it from. Having this complete at the outset can prevent unnecessary stress later on while looking for a trustworthy service provider.
Contact previous customers to enquire about the company's service and assistance. A trustworthy reseller will answer questions by phone or email after the sale and installation. Check if the reseller offers maintenance to avoid future troubles. Routine maintenance can save money over time. Technicians who have received proper training can spot signs of wear and malfunction and replace them before the equipment breaks down.
Advantages of Using a Metal Laser Cutter
