To keep these high-tech tools running smoothly, reliably, and for a long time to come, regular maintenance on laser cutters is essential. To keep laser cutters running smoothly and accurately, which affects both the precision of the cuts and the efficiency of the operations as a whole, regular maintenance is a must.
Problems like decreasing cutting precision, deteriorated cutting quality, or expensive breakdowns leading to production delays and increased downtime might arise from neglecting maintenance. Thus, in order to avoid problems and maximise the efficiency of laser cutters, it is crucial to take a proactive approach to maintenance.
Preventative maintenance allows you to catch small flaws with the system early on and fix them before they become big problems. Lenses, mirrors, mechanical parts, and electrical systems are among the most important components that operators can clean, inspect, and service on a regular basis to keep them running well and prevent unexpected malfunctions. In addition, to keep the warranty valid and make sure the machine runs well, follow the manufacturer’s suggested maintenance schedule and instructions to the letter.
Why is it important to keep your laser machine well-maintained?
There is a continual stream of smoke, fumes, and debris produced by the intense laser cutting process. All of these factors contribute to the dirt accumulation inside your machine and its attachments. When this buildup occurs, it can lead to overheating and system failures.
The material being processed and the machine’s operation determine the amount of maintenance that is necessary.
Engraving on aluminium, for instance, results in negligible burn-off. There may be less of a need for cleaning as a result.
Nevertheless, a great deal of smoke and gas will be produced when processing materials such as foam, rubber stamps, or leather, and this can rapidly obscure the machine’s inner workings. In that instance, you should clean more frequently.
The probability of your machine experiencing downtime can be reduced through routine maintenance.
When comparing CO2 with fibre lasers for preventative maintenance, what are the main differences?
The optics within the resonator and the beam delivery mechanism are the main points of differentiation between fibre lasers and CO2 lasers in terms of preventative maintenance. The resonator optics that assist create and enhance the laser beam are present in all CO2 lasers, but they are not present in most fibre lasers.
The cutting head of every carbon dioxide laser is supplied with the laser beam by means of beam path optics, also known as bend mirrors. Instead of using bend mirrors, the beam is sent from the resonator to the head of a fibre laser using a fibre optic cable.
Beam path bellows, which encase the bent mirrors in the CO2 laser, are prone to holes caused by continuous movement and back reflections; hence, they need to be replaced at regular intervals. Part tip-ups can also cause beam path optics to become misaligned in severe head crashes.
For optimal cutting efficiency, it is necessary to clean, realign, and replace all optics on a regular basis. Nevertheless, in comparison to fibre lasers, CO2 lasers are typically more accommodating, and the cutting head optics of these lasers are less affected by hazy conditions.
While fibre lasers require significantly less preventive maintenance than other types of lasers, it is still imperative that they be kept clean, that they be serviced in accordance with the factory’s instructions, and that they be operated in a dust-free, controlled environment.
When planning preventative maintenance for fibre lasers, what parts of the device are most likely to be neglected?
Although it’s easy to avoid all of them, there are a few unfortunate ones. Slag accumulation and cutting head accidents were previously brought up. Excess slag can cause cut portions to tilt up, which poses the danger of the head colliding with the projecting part. The cost to replace a damaged head could reach several thousand dollars if this happens.
Be careful to use the right cleaning solutions and to carefully wipe down the lens and lens window after each use. Always go with high-quality OEM parts made for the specified machine, even if aftermarket lenses, lens windows, nozzles, insulators, or non-spec consumables can save you a few bucks initially.
How may slag be most effectively removed or avoided?
Slag buildup from slats can be easily removed with a motorised tool that is offered by several vendors. I’ve also seen businesses who spray the slats with a solution that’s comparable to welding anti-spatter and have moderate success in reducing slag formation.
Copper slats are, in my opinion, the most effective, long-term option. They cost a pretty penny to buy, but when it’s time to replace them in four or five years, you may get most of it back in copper scrap.
Making sure the slats are double-sided allows you to easily switch them over when the top side gets worn, which is another cost-saving measure to take. Since the material’s position inside the laser is affected by the overall height of the slats, it is crucial to consider this factor. Because the Z-axis motion is about to surpass the soft limitations of the machine’s settings, the laser will suffer height sensor alerts when processing thin-gauge material when the slats become too short.
The Advantages of Regular Maintenance
Preventative maintenance on laser cutting machines has various advantages. The machine’s lifespan is extended when maintenance is kept up to date. As a fabricator, you should try to see the big picture rather than the short when it comes to your investment in lasers. Preventative maintenance extends the life of your laser machine and keeps it clean, which improves performance and reduces unplanned downtime.
Fabricators can save money with preventative maintenance, which is the most critical benefit. One way fabricators can save money is by reducing the amount of time their laser machines sit idle. This will lead to lower service fees.
Finding a way to lower a service cost would be a fabricator’s holy grail. It is important to clean the laser before a service engineer arrives at a laser-cutting machine to avoid wasting time during the appointment. A vital first step in servicing processes is having your laser machine cleaned, which can lower the cost of service.
Fabricators would prefer not to have an idle machine impeding productivity, even though a reduced service visit bill is fantastic. Preventative maintenance is a great way to keep machines running as much as possible. Fabricators can get back to creating parts and making money if their laser-cutting machines are up and running again after maintenance as soon as possible.
Tips for Keeping Fibre Lasers Clean
Laser operators should know what to check for before getting cleaning supplies for a fibre laser unit. When cleaning or doing preventive maintenance on fibre lasers, it is best to focus on the following areas.
Torch
When cutting with a laser, the torch is where all the action is. The operator of the laser can clean the torch’s body, the wires and cables connecting to it, the nozzle, and the protective window. You should also check the cover over the Z-axis to see if it needs cleaning.
You can clean the torch with Texwipes or an isopropyl alcohol-soaked clean lint-free cloth. Make sure the torch is clean by wiping down these locations. Maintaining a clean torch is essential for consistently high-quality laser operations.
Drive System
The drive system is another part of the laser equipment that needs regular maintenance. The laser machine’s X, Y, and Z axes are controlled by the drive system, which guides the torch during cutting operations. Keep an eye on the belts and bellows that are part of the drivetrain.
After each usage of the laser cutter, clean the belts and bellows with a gentle brush, vacuum, or rag to eliminate any debris. Premature failure and wear can be avoided by keeping these drive components clean.
Slats
It is important to inspect the slats before cutting them as well. Check the height of the slats on a regular basis. Your laser will not be able to start cutting processes if the slats are not at the correct height because of wear. If your laser has software limitations, the torch will try to go below them, but it will be unable to and will trigger an alarm.
To keep your slats at the correct height and prevent slag development, you can either use tools designed for this purpose or remove the buildup by hand.
Make sure there is no dross, grease, or other debris in the designated places; otherwise, cutting may not go smoothly. Be sure to take all necessary safety measures when cleaning your laser. Make sure the power is off to your laser cutter before you do any maintenance.
To make sure it doesn’t switch on while you’re cleaning, you can also push the emergency stop button. The likelihood of fires occuring during operations can be reduced by cleaning using the appropriate materials. It is critical to remain current while organising and carrying out preventive maintenance operations, now that you are familiar with the fundamentals of fibre laser cleaning.
Conclusion
Regular maintenance on laser cutters is crucial for their smooth operation and efficiency. It helps prevent issues like decreased cutting precision, deteriorated cutting quality, or costly breakdowns, which can lead to production delays and increased downtime.
Preventative maintenance involves cleaning, inspecting, and servicing components like lenses, mirrors, mechanical parts, and electrical systems. Following the manufacturer’s maintenance schedule and instructions ensures the machine runs well and prevents accidents. The amount of maintenance required depends on the material being processed and the machine’s operation.
Fiber lasers require less preventative maintenance but still need to be kept clean, serviced according to factory instructions, and operated in a dust-free environment. Slag accumulation and cutting head accidents are common issues.
Slag buildup from slats can be removed using motorized tools or spraying with a solution similar to welding anti-spatter. Copper slats are the most effective long-term option, costing less but returning most of the material in copper scrap.
Double-sided slats are cost-saving and can be easily switched over when worn. Regular maintenance on laser cutting machines extends the machine’s lifespan, improves performance, and reduces unplanned downtime. Fabricators can save money by reducing idle time and lowering service fees.
To keep fibre lasers clean, operators should focus on the torch, drive system, and slats. Regular inspection of the slats and the drive system is essential for maintaining high-quality operations. Safety measures, such as power off and emergency stop buttons, are also crucial.
