What is the fiber laser cutting machine?

The fiber laser cutting machine is a mechanical CNC laser cutter that uses a fiber laser source to output a high-energy-density laser beam, which instantly melts and vaporizes the area illuminated by the ultra-fine focus spot on the workpiece, and moves the spot irradiation position through a numerical control mechanical system, thereby achieving cutting.


What is benefits of laser cutting?

Compared to other types of cutting, laser cutting offers several advantages. These include:


  • Greater cutting precision and accuracy
  • Higher quality edges
  • Narrower kerf widths
  • Smaller HAZ and less material distortion
  • Less material contamination and waste
  • Lower maintenance and repair costs
  • Greater operator safety

Laser cutting machines are capable of cutting a wide range of designs with a greater degree of precision and accuracy than more conventional cutting machines. Since laser cutting machines can be fully CNC controlled, they can repeatedly and consistently produce complex and intricate parts to high tolerances. Laser cutting also produces high-quality cuts and edges which generally do not require further cleaning, treating, or finishing, decreasing the need for additional finishing processes.


The focused beam allows for narrower kerf widths, and the localized heating allows for minimal thermal input to the bulk of the material being cut. The smaller kerf minimizes the amount of material removed, and the low thermal input minimizes the heat affected zones (HAZs) which in turn decreases the extent of thermal distortion. The non-contact nature of the laser cutting process also decreases the risk of mechanical distortion, especially for flexible or thin materials, as well as decreases the risk of material contamination. Owing to the tighter tolerances, narrower kerf widths, smaller heat affected zones, and lesser degrees of material distortion, laser cut part designs can be arranged closer together on the material. This closeness of design reduces the amount of material waste, leading to lower materials costs over time.


While the initial investment in laser cutting equipment is typically higher than with other cutting processes, running and maintenance costs are comparatively low. Laser cutting machines are capable of performing multiple operations and applications without the need for purchasing or changing out separate, custom-designed tooling; this characteristic of laser cutting decreases both the total equipment costs and the lead time between different processes and applications. Additionally, as laser cutting is a non-contact process, the laser components experience less fatigue—and consequently last longer—than components in contact cutting processes such as mechanical cutting or rotary die cutting. Together with the relative inexpensiveness of replacement laser components, the durability of laser components further decreases the total equipment costs over time.


Other advantages of laser cutting include decreased risk of operator injury and quieter operations. The laser cutting process employs little to no mechanical components and occurs within an enclosure, therefore there is less risk of operator injury. As there is less noise produced during the laser cutting process, the overall workplace environment is also improved.


What is limitations of laser cutting?

While laser cutting demonstrates advantages over other forms of cutting, there are also limitations to the process, including:


  • The range of suitable materials
  • Inconsistent production rate
  • Metal hardening
  • Higher energy and power consumption
  • Higher equipment costs

As indicated in previous sections, laser cutting is suitable for a wide range of metals and non-metals. However, the material being cut and its properties often limits the suitability of some cutting mechanisms, assist gases, and laser types. Additionally, the material thickness plays a significant factor in the determination of the optimal laser power, assist gas pressure, and focal position for a laser cutting application. Varying materials or varying thicknesses within a single material also necessitate adjustments to the cut speed and depth throughout the cutting process. These adjustments create inconsistencies in production time, as well as increase the turnaround time, especially in large production runs.


One advantage of the laser cutting is the production of high-quality cuts which generally do not require extensive secondary cleaning, treating, or finishing. While in some respect this is advantageous, the resultant work hardening of the laser cut edges may be problematic for some applications. For example, parts requiring further processing, such as powder coating or painting, will first need surface treatment following the laser cutting process before receiving the necessary coating or paint. The addition of this step increases both the turnaround time and total processing costs.


While laser cutting can have lower maintenance and material costs over time, for some manufacturing applications, it may be more cost-effective to use other cutting processes. For example, while both metal and non-metal materials can be laser cut, laser cutting plastic causes the emission of potentially harmful and toxic gases. These emissions necessitate air pollution control equipment, increasing the necessary equipment costs. For manufacturers and job shops starting up, although replacement and maintenance parts are relatively inexpensive, the initial investment in laser cutting equipment also tends to be much higher compared to more conventional cutting processes. Additionally, laser cutting equipment typically consumes more power and energy than other cutting processes, leading to further increases in operating costs. Altogether, the high initial equipment and operating costs may make laser cutting unsuitable for low budget operations.


Why choose the fiber laser cutting machine?

1. High cutting accuracy: The positioning accuracy of the metal laser cutter reaches 0.05 mm, and the repeated positioning accuracy reaches 0.03 mm. 2. Narrow slit: The width of the slit is generally 0.10-0.20 mm. 3. Smooth cutting surface: There is no burr on the cutting surface, and the roughness of the cut surface is generally controlled within Ra6.5. 4. Fast cutting speed: the cutting speed can reach 10 m / min, and the maximum positioning speed can reach 30 m / min. 5. Good cutting quality: Adopting non-contact cutting, the cutting edge is affected by heat little, there is basically no thermal deformation of the workpiece, to ensure that the workpiece is not scratched, and the slitting generally does not require secondary processing. 6. Laser processing has good flexibility: the fiber laser cutting machine can process arbitrary graphics, and it can cut pipes and other profiles without being affected by the shape of the workpiece.

Why does fiber laser cutting machine so popular?

When it comes to metal fabrication it often seems like the majority of technology has been around for decades with some minor changes and updates. While some technology will always produce a great cut and be a good choice for a metal fabrication shop, there is a constantly evolving world of technology. In recent years fiber laser cutting has grown in popularity amongst metal fabricators. There are many reasons for this but to truly understand why it has become so popular it is important to understand what fiber laser cutting is and what differences it brings to the table. When compared with other methods of metal fabrication, fiber laser cutting is a pretty new technology. Industrial Laser Solutions provides a helpful description of how fiber laser cutting works, “Fiber lasers, on the other hand, employ solid-state diodes to pump molecules that are captured in an optical active double clad fiber with an ytterbium-doped core. The pumped light excites the core, and the light exits the module via a transport optical fiber that carries the beam to the focusing head where cutting takes place. The need for laser gas is eliminated as all collisions between molecules take place within the optical fiber, which in turn requires far less energy — about one-third that of a comparable CO2 laser. And because less heat is generated, the size of the chiller is proportionally reduced. In general, overall energy consumption is 70% less than a CO2 laser performing the same task.”


When it comes to the use of fiber lasers for cutting, efficiency is the name of the game. Not only is it more energy efficient but it expedites the cutting process. By expediting and streamlining the cutting process, it costs far less to produce a cut or part which ultimately improves your business’ profitability and enhances the return on your investment in a new CNC cutting system.

Where to use fiber laser cutting machine?

Fiber lasers have grown in popularity so significantly because they can be used in a wide range of industries for a variety of materials.

Fiber laser cutting is precise, efficient, low maintenance, and easy to on-board in any facility. If you think your shop or facility could benefit from the advantages of fiber laser cutting, Machitech Automation is happy to answer any of your questions and assist you in choosing the right CNC fiber laser cutting system.

Why should you use a laser cutting machine?

Since laser light has unique properties as mentioned above, it can be harnessed for many applications and among them is for cutting hard materials. A laser cutting machine works by dispersing the enormous amount of energy it produces, and the focused light emission hits the intended target to either soften the material or evaporate it for complete removal. A cut is created by either moving the object that needs to be cut through the laser beam or by moving the laser beam itself over the surface of the object.


Laser cutting machines are in high demand since they can be diversely used for several applications. By using a CNC fiber laser cutting machine, metals with complicated profiles and forms can be effectively and consistently cut. Its excellent cutting capacity and quick cutting velocities eliminate the preparation of metals and lowers the cost of production to improve the profitability for companies that leverage the innovative technologies. As a result, companies in the position to buy these products are looking for reputable manufacturers and sellers online, and are interested in comparing each of the machine’s specifications to one another. Some of these companies that manufacture laser cutting machines have top of the line R&D teams that can redesign, reconfigure, or develop machines as per the client’s unique requirements.


The development technology in CNC fiber laser cutting machines incorporates the level of beam quality, laser control, usability and operation of the material, and make it possible for a laser cutting machine to cut metals that have multi-dimensional profiles. These popular laser cutting machines with this caliber of functionality are very useful in all types of mechanical industries.

How to repair our fiber laser marking machine?

When the fiber laser marking machine is not working. In case of any fault of fiber laser marking machine, the power supply of marking machine and computer should cut off immediately.

Cover the field lens to prevent dust from polluting the optical lens.

If the equipment use for a long time, the dust in the air will absorb on the surface of the lower end of the focusing lens, which will reduce the power of the laser and affect the marking effect. In serious cases, the optical lens will overheated and burst. When the marking effect is poor, the focus lens surface should carefully check for contamination.

If the surface of the focusing lens is contaminate, remove the focusing lens and clean its lower surface.

Take special care when removing the focus lens, and be careful not to damage or fall. At the same time,do not touch the lens with hands or other objects.

The cleaning method is to mix anhydrous ethanol (analytical pure) and ether (analytically pure) in the ratio of 3:1 and use long fiber cotton swab or lens paper to invade the 8 mixture, and gently scrub the lower surface of the focusing lens.

The cotton swab or lens paper must be replaced once every side is rubbed.

During the operation of fiber laser marking machine, do not move the marking machine to avoid damaging the machine.Do not cover piles or other objects on the fiber laser marking machine .


How to maintain a fiber laser cutting machine?

The simplest thing you can do to prolong the life of your fiber laser cutting machine is to clean it. Operators must clean the device after every job. So please, empty all slag drawers and bins before attempting a new cut. If a worker doesn’t unpack a drawer after they use it, it’ll eventually jam shut. This can dramatically affect the table shuttle. Workers must clear off the slats before attempting another cut. Remove all scraps so that the new material lays flat on the surface and doesn’t tip upward.


Once you’re confident that the slat and drawers are clean, examine the torch. The torch is the nucleus of a fiber laser cutting machine. If this part malfunctions, there will be big trouble in the future. So, workers should clean the torch body, nozzle, attached cables, and the protective window. Operators can use lint-free cloths or microfiber towels to clean these parts. Cleaning the torch helps the laser make the most precise cuts possible.


It’s crucial to clean the area around the equipment as well. Any debris or scraps that surround the machine are a safety hazard. Workers can trip over these items and severely injure themselves. So, clean up and do a thorough inspection of the area before you turn it on. Also, check over the connections and watch out for loose wires that may cause you to trip. Cleaning is a simple task that can prevent massive headaches in the future.


When check gas?

Fiber laser cutting machines use gas to operate. These gases assist the laser in vaporizing through a material. Contaminated gases greatly impact the quality of the cut. If you want a smooth cut every time, the gas must be as clean as possible. Inspect the gas when you can to ensure that it’s free of debris. Also, look over the filters to make sure they’re doing their job. Workers should replace the gas bottle every time they notice a leak, too. Seepages not only slow down the flow rate, but they also affect the equipment’s performance. Also, leaks are a safety hazard to operators working with the device. It’s fairly simple to fix a gas leak in a fiber laser cutting machine. First, you must make sure the device is off. Then, you can use a soapy rag to rub the connection line after you replace the gas bottle. Workers must address a leak the minute they see one. Ignoring the problem will worsen the situation down the line because productivity will decrease, and your safety could be at risk.

How to control temperature?

Much like plasma cutting systems, fiber laser cutting machines vaporize metal using heat to cut through materials. Operators must do everything they can to keep the equipment cool, so it doesn’t overheat. People must check the system’s coolers regularly to ensure they’re working as they should. Coolant levels, filters, and fans need to be cleaned so they can perform their essential functions. If a fan or a filter is covered in debris, they can’t cool the fiber laser cutting. If a fiber laser cutting machine gets too warm, this can cause detrimental issues for shop owners. You can prevent the need for major repairs by frequently checking on the machine’s cooling systems.


Don’t neglect the track

A fiber laser cutter must be straight to get the highest quality cuts possible. So, workers must look over the verticality of the track and the straightness of the machine every few months. When the machine is uneven, the cut is inaccurate. For starters, the edges of the material may be very jagged and not smooth. Or, the material may not be cut all the way through. Operators have to make simple changes to fix these issues. Workers can tighten bolts and screws to straighten things up. Operators should also make sure that the steel belt is tight to prevent lagging. If the problem worsens, operators should call manufacturers immediately. The expert team at Mac-Tech is dedicated to keeping every shop as efficient as possible. We know how detrimental device malfunctions are. We want to help you get up and running as fast as possible, so you don’t lose any revenues.


Fiber laser cutting machines are essential pieces of equipment that every shop should have. These devices help metal fabrication shops be more productive. These laser devices can perform functions that no one could possibly do on their own. However, major repairs create severe headaches in the future. Significant fixes take a lot of time to fix. This means the equipment is powered off, and production stops. If you want to keep your establishment running smoothly, you must perform preventative maintenance on these machines, so it is important to know how to maintain a fiber laser cutting machine.


Operators must clean the machine before they use a device. Debris greatly affects the quality of the cut. So, people must clear off the equipment to ensure things run smoothly. Surprisingly, people can use vacuums to assist them in their cleaning efforts. Vacuums can be used to clear away any unwanted dust that’s causing issues. After cleaning, operators should check the gas as well as the track. If these components are working as they should, and the machine isn’t overheated, the fiber laser cutting machine should last for years to come. If these steps are ineffective, contact the machine’s manufacturer for further assistance. Customer satisfaction is Mac-Tech’s number one priority. We won’t rest until your devices are operating as they should, and your employees feel safe on the job.


When keep it cool?

As LASER cutting systems are in essence a thermal cutting process just like plasma and oxy/fuel cutting systems they vaporize material through a heating process. Because if the extensive heat created and the electrical components inherent in every Laser Cutting System it is of paramount importance that they are thus adequately cooled. Chillers are a critical aspect of any C02 or Fiber Laser Cutting System and as such must be checked periodically, cleaned and maintained. While newer Fiber Laser Technology requires a far smaller chilling system it is still critically important to the proper operation and life of your laser system. Filters, fans, coolant levels, coolant quality and cleanliness should all be checked on an interval set forth by your machines manufacturer.


Today's Laser controls have a myriad of built in maintenance reminders and options including direct links online to your machine manufacturers service department. More systems even include on-board maintenance manuals and interactive videos which take a user step by step through the maintenance process. These newer controls also allow a user to schedule maintenance in accordance with their production schedule. Whether you choose to follow a maintenance schedule manually in a handwritten log book or via the sophistication of today's controller technology, proper maintenance to your CO2 or Fiber Laser Cutting System is a crucial step in maintaining your profitability, keeping your down time in check and keeping your laser cutting system burning longer.


When keep optics clean?

As CO2 systems require a beam path delivery system (replaced by the Fiber Optic Cable on newer Fiber Lasers) there are many more “Optics” in a CO2 system and therefore it is much more extensive a system and as such, much more important to ensure your CO2 laser cutting systems optics are clean and free of debris. Both CO2 and Fiber Laser Cutting Systems both use a series of lenses at the cutting head, whereas these are also critically important to be kept clean and free of debris and contaminants. Any contamination in the cutting head will quickly lead to cutting performance deterioration and eventually (sometimes very quickly) a damaged lens requiring replacement.
