Enclosed Fiber Laser Cutter

*Laser Source: Enclosed fiber laser cutting machines use a high-power fiber laser source to produce an intense and focused laser beam for cutting. Fiber lasers are known for their efficiency and reliability.
*Laser Head: The fiber laser cutting head receives the laser beam and converts it into the cutting surface. The laser beam passes through a nozzle that sprays a compressed gas, such as nitrogen or oxygen. The distance between the cutting head and nozzle, the intensity of the beam, and the speed of the laser beam and cutting head all affect cut quality.
*Focusing Lens: Laser cutting machine focusing lenses come in different sizes to perform different jobs. Each lens is identified by inch measurements. This measurement does not refer to the size of the lens. Instead, it refers to the focal length from the material you are cutting. Each lens will produce a different spot size on the material you are cutting.
*Laser Focusing System: A metal-cutting laser is most powerful when it is focused on the smallest area. Focus is related to the focal length of the lens. A lens with a smaller focal length has a tighter focus and shorter depth. This is why shorter length lenses are better for detailed work. Lenses with longer focal lengths have greater focus and greater depth.
*Air Assist Gases: The most common air assist gases are oxygen, nitrogen, and air. In rare cases, argon gas can be used. The main function of the air assist gas is to spray the heated material for laser cutting.
*Cooling System: A cooling system is connected to the closed fiber laser cutting machine to cool the laser source and cutting head that may be damaged by high heat. The cooler automates the cooling process by maintaining the laser at an optimal temperature of 22-23 degrees Celsius. There are two main types of chillers: air chillers and Freon chillers. The air cooler cannot cool below room temperature. They may not have automatic monitoring or warning features. Freon chillers can cool down to below room temperature.
*Computer Control System: The control system controls the cutting head position, nesting, power size and cutting accuracy. Without a high-quality controller, you won't be able to get the complex and detailed results you need.
*Software and Cutting Files: Laser cutting software is used to program fiber laser metal cutting machines. A good software will make it easy to control every aspect of your laser cutting operation, which will increase your productivity and make operating your laser cutter much easier. CYPCUT is one of the best laser cutting software options for sheet metal cutting. For higher power cutting above 6kW we recommend using HYPCUT software instead. A good laser cutting software must have an intuitive user interface that gives you complete control over the operation process.
*Ventilation/Exhaust/Dust Removal Components: Fiber laser cutting machines produce large amounts of dust and fumes that are harmful to breathing. The cut material will be blown away and will need to be disposed of. Proper ventilation and dust collection are important for the safety of laser cutting machine operators. An exhaust system that uses filters removes particles from the air and expels the air outside or sends it to a location of your choice.
*Enclosed Enclosure: Fiber laser cutting machines can have enclosed cabinets or open workbenches. Open machines (sometimes called flatbeds) can be a safety hazard in certain situations. You may need to purchase additional safety equipment. Enclosed fiber laser cutting machines can avoid these dangers. Fully enclosed design provides a safe working environment. Not only does it protect the operator from the laser beam, it also contains the smoke and debris generated during the cutting process.

Budget
Determine your budget for purchasing a laser metal cutting machine, taking into account the initial investment as well as any additional costs for installation, training, maintenance and support. The budget directly affects the configuration of the machine. If your budget is limited and your main goal is to cut sheet metal, then you can go for a single-platform laser metal cutting machine. If you have a larger budget, you can choose a fully enclosed fiber laser cutting machine.

Material
Choose the right laser cutter based on the material you want to cut. If you frequently cut metal, then fiber laser metal cutting machine is your best choice, such as cutting iron, carbon steel, stainless steel, etc. Due to the particularity of the material itself, it will lead to unstable operation and destructive automatic shutdown during the processing, and even cause great damage to the laser and shorten the life of the laser. You also need to consider the thickness of the material. Make sure the machine you choose is suitable for your material requirements.

Power and Capability
Machines with higher power can generally cut thicker materials and have faster cutting speeds. Check the machine's specific capabilities, such as its maximum thickness for bevel cutting or 3D cutting. At present, many fiber cutting laser machines have reached 60,000w, which can meet the cutting needs of most thicknesses.

Cutting Area and Bed Size
Determine the cutting area and bed size required for your application. Make sure the machine can handle the size of the material you want to process. The most common working area is 3050*1530mm, which is what we often call the 3015 model laser metal cutting machine. Other models: 4020, 6025, 6020, etc.

Cutting Speed and Efficiency
Evaluate the machine's cutting speed and efficiency. Higher cutting speeds increase productivity while reducing production time. to extend production time. To improve efficiency, look for a fiber laser cutting machine with automatic functions, which will save you a lot of time and labor costs.

Precision and Accuracy
The precision and accuracy of fiber cutting laser machines are mainly due to servo motors and linear guides, which can provide precise and accurate cutting. You'll also want to check the machine's repeatability and tolerance levels.

Software and Control System
To streamline your production, look for fiber laser cutting machines with user-friendly software and systems. Many CNC fiber laser cutting machine systems all use CYPCUT control system, which is a set of software specially developed for the laser cutting industry. It is easy to use, rich in functions, and suitable for various processing techniques.

Maintenance and Support
You'll also want to consider the machine's maintenance requirements and the availability of technical help. Check whether the manufacturer or supplier provides training, maintenance and spare parts support. This will help you save a lot of unnecessary time and costs.

Laser cutting is a powerful tool that enables easier, faster manufacturing across all sectors of industry. It is part of the explosion of CAD/CAM, automation, and advanced materials in the industrial revolution. Not all materials, however, lend themselves to this processing method. Some resist, and others offer more dramatic and/or messy outcomes. These bad materials to use for laser cutting are listed below:
ABS
ABS (acrylonitrile butadiene styrene) does not volatilize under laser cutting but tends to melt and burn. Cut edges are melted and fused. ABS thermal/oxidative decay products contain a wide range of toxins, including: cyanide, phenol, phenyl cyclohexane, and benzene derivatives, etc. ABS is also generally considered to be a fire risk because the lack of removal of material by char/volatility leads to considerable local heating and ignition.

Epoxy
Epoxy resins (or polyepoxides) are very ill-suited to laser cutting or engraving. The quality of results is generally considered poor and gas byproducts are highly toxic. Though hydrogen cyanide is widely discussed as a byproduct, quality research on “typical” epoxies in thermal degradation lists “H2, CO, CH4, C2H6, C2H4, C3H6 and C3H8, ethane, ethylene, propylene, and propane” and not HCN. However, epoxies are a wide family, differentiated by catalysts and details of pre-polymer manufacture, so HCN cannot be ruled out as a byproduct. It’s worth noting that polyester resins are sometimes mistakenly referred to as epoxies, while they are chemically unrelated. While polyesters are much more difficult to use, they respond better to laser cutting, so a thorough understanding of the materials you want to cut is central to achieving good outcomes.

Polypropylene
Polypropylene is often listed as unsuited for laser cutting. Polypropylene tends to melt and fuse during cutting which results in residues overheating and smoking. However, the smoke is not considered particularly harmful, other than as a mild irritant. A filtered extraction system will usually address this aspect. Cut quality can be improved (and smoking reduced) by effective air assistance.

PVC (Poly Vinyl Chloride)/Artificial Leather/Leather/Vinyl
PVC’s thermal degradation releases chlorine gas and hydrogen chloride once dissolved in moisture. While these damaging and very toxic byproducts can, in principle, be removed by extraction and good quality filtration, the harmful effects on equipment and risk to operators make this material unsuited to laser cutting.

Fiberglass
In benchtop equipment, fiberglass is considered a no-cut material. Few, if any, small machines are capable of cutting the glass fiber component well. The (widely used) resins are described as “releasing toxic gases.” Most fiberglass (GRP, glass-reinforced polyester) is not epoxy bonded but uses polyester resins, which are more commonly considered cuttable. However, polyester resins are a broad family, and much fiberglass material will not be identified easily by resin type. Avoiding cutting fiberglass composites on small and modestly ventilated machines is a good choice.

Polycarbonate
Thin PC is practical for cutting. In sections greater than 1 mm, however, melt/fusion and heat-affected zone (HAZ) discoloration (yellowing) is significant. However, higher power machines (in the kW range) are reported to successfully cut PC. The higher power encourages more vaporization and therefore less heat transfer to the bulk, from melt residues.

HDPE/Milk Bottle Plastic
HDPE cuts very poorly. It makes a melted, fused mess and is not considered suitable for laser cutting by benchtop machines. Machines with considerably higher power are likely able to volatilize more of the material, reducing the melting heat transferred into the HAZ. Aggressive air assistance is helpful.

Glued Materials
“Glued” is a broad term, and a deeper analysis is required. Plywood is a glue-laminated board made of alternating grain veneers. It is usually bonded with phenolic resin and, because the resin layers are very thin, it generally cuts well. Phenolics release formaldehyde when cut, so good extraction and a carbon filter mask are must-haves. MDF is also a commonly phenolic bonded board, though made of compressed fibers rather than veneers. It is safe and effective to cut, with extraction and a filter mask. Wooden components bonded with PVA (polyvinyl acetate) adhesives are safe to cut. Cyanoacrylate adhesive bonded materials, however, produce severely irritating fumes when heated. Extraction and a breathing mask with closed-eye protection are required. If the glue requires cutting properties that differ greatly from the matrix and is present in gap-filling quantities, it can be hard to find compromise settings that enable both cuts in the same pass.
