The laser cutting machine must be assisted by auxiliary gas during processing! Generally, there are three auxiliary gases we use most, namely oxygen, nitrogen, and air. Of course, the higher the gas purity, the better the cutting quality. When conditions permit, air-assisted cutting by laser cutting machines is the cheapest way. However, there will often be water mist on the protective lens during air-assisted cutting, not only the cutting speed is very slow, but the cutting quality is also poor.
First of all, let everyone popularize the role of auxiliary gas:
1) In order to blow away the residual waste, to achieve the best cutting effect.
2) Use gas to blow away the metal slag while protecting the lens to avoid the slag sticking to the lens and affecting the cutting quality.
3) It can effectively achieve the effect of smooth cutting surface, no burrs, and no dregs, which belongs to fine cutting.
4)It can react with the material and increase the cutting speed. For example, the use of oxygen can achieve the combustion-supporting effect.
In the hot and humid south, it is very normal for metal materials such as iron plates and carbon steel to rust. Can the rusty plate be cut directly with a laser cutting machine? The answer is of course: no
Everyone knows that a fiber laser cutting machine is an artifact that cuts iron like mud, but the laser of the metal fiber laser cutter is powerless on the rusted surface. Because the laser itself cannot be a light source, heat will only be generated after being absorbed by the surface of the sheet metal workpiece. For unrusted materials and rusted materials, the laser absorption is very different, and the cutting effect is also different.
Taking the rusty sheet below 5mm as an example, the cutting condition of the uniformly rusted sheet will be better than the unevenly rusted sheet. Because the uniformly rusted sheet absorbs the laser evenly, it can be cut well. For the processing of materials with uneven rust on the surface, the surface condition of the material must be uniform before cutting. Of course, when conditions permit, it is recommended to use a grinder to remove rust.
For thicker rusty plates, if you use a laser cutting machine to cut the rusty plates directly, it is easy to cause the phenomenon of impervious cutting, poor cutting quality, and even slag splashing, which may cause damage to the protective lens, or even the focus lens, causes the ceramic body to burst. Therefore, if you cut thick rusty materials, you must remove the rust before cutting.
The parameters that affect the cutting quality are: cutting height, cutting nozzle model, focus position, cutting power, cutting frequency, cutting duty cycle, cutting air pressure, and cutting speed. The hardware conditions include protective lens, gas purity, plate quality, focusing lens, and collimating lens.
In the case of poor cutting quality, it is recommended to perform a general inspection first. The main inspection contents and order of the general inspection are:
1)The height of the metal fiber laser cutting machine. If the actual cutting height is not accurate, calibration is required.
2)Check whether the cutting nozzle type and size are wrong, if it is correct, check whether the cutting nozzle is damaged and the roundness is normal.
3)It is recommended to use a cutting nozzle with a diameter of 1.0 to check the optical center. The focus should be between -1 and 1 when checking the optical center. The light spot is small and easy to observe.
4)Protective lens. Check whether the protective lens is clean. It is required to be water-free, oil-free, and free of residue. Sometimes the protective lens may be fogged due to the weather or the air is too cold.

A fiber cutter is an industrial machine used to process and manipulate metallic materials, in other words, metal fabrication. It is not meant for engraving or marking metals, though you can do simple stuff such as serial number or barcode engravings. Intricate pattern engraving is not what a fiber cutting machine is meant for. It is not recommended for cutting organic/ acrylic/ plastic/ glass materials.
60-90 days. From the starting point of getting your customized machine built, shipping logistics, to the machine's QC process here at Anaheim, California . We make sure that everything is perfect before it is shipped to you. We will then schedule a machine installation and training date, including electrician setups and a fork-lift rental.
IPG laser is a US-based photonics company with a 2-warranty attached to it. They have their own technical support team, and are highly recommended for mass production and precise manufacturing. On the other hand, MAX is an overseas laser head brand with a dial based fiber source and an economical power usage model. It is great for prototype manufacturing and it requires slightly more power to be comparable with IPG laser sources.
We'd highly recommend it if your fiber machine is performing at 3kw or higher. We also recommend having a covered model if you have a busy workshop with a continuous workflow or have flammable materials laying around the machine.
If your machine is operating in colder weather, you would need an antifreeze coolant to keep the laser flow constant, otherwise it will cause issues within the laser optical system. If you are operating in a very hot environment, we would recommend having AC within your workshop to prevent machine from overheating. Furthermore, you will need to switch on your industrial water chiller and wait for it to get to an optimal temperature of 22-23 degrees celcius before switching on your laser source. If your machine is operating in humid weather, moisture may effect the laser powersource, and it can cause the machine to shut-down.
First of all, make sure the laser optics are clean to maintain precise cutting. Maintain properly deionized water (chiller system) and airfiltration system every 3 months. Check on the electrical cabinet every 6 months, dust off any unwanted debris, check on the transformers and tighten the connectivity to make sure machine runs properly.
Our 4-Core Dust Collector comes with 5.5KW of power; we recommend this collector for laser machines between 1.5-6KW. If you are looking for dust collector systems for a laser-cutting machine over 6KW, contact our sales representatives for a comprehensive rundown of our different products.
Our fiber-laser cutter machines come with their own built-in ventilation system to expel exhaust from the workspace. This system includes an exhaust fan and duct to suck up the pollutants and vent them out the back of the fiber-cutter machine.
The difference between the enclosed-bed and open-bed fiber cutters is their power levels, software, and laser head. An open-bed fiber-laser cutting machine can sustain a power of 1.5-4KW, while an enclosed fiber-laser cutter can sustain a power of 6KW and above.
Additionally, the enclosed fiber-laser marking machine uses different software and different laser heads.
The fiber-laser cutter runs off a 3-phase connection and requires a standard voltage of 380V. A transformer and stabilizer are included with the purchase of a fiber cutter, allowing for 220V, 240V, and 480V to be used as well.
The amperage for a fiber-cutting machine is based on the fiber-laser source, its power, the voltage utilized, and the unit itself. If you want to calculate the amperage draw of your laser cutter, use this calculator.
IPG
MAX
The main difference between the IPG and MAX power sources we use for our fiber-laser machines is their country of origin. IPG is the industry’s leading fiber-laser source in the US, while MAX is the leading fiber-laser source in China.
MAX presents a moderate price rating, while IPG is more expensive. However, units with IPG receive faster repair time in the US. Most importantly, IPG is designed specifically for highly reflective materials. This G5 feature is built into the IPG power source but is an additional purchase for the MAX (available for 6KW machines and above).
