The narrowness of the energy beam and the precision with which the material and/or the laser optics can be moved ensures extremely high cutting quality. Laser cutting allows the execution of intricate designs that can be cut at high feed rates, even in difficult or fragile material substrates.
Traditional rotary cutter processing of materials requires coolants to be applied. The coolant can contaminate the cut parts, which must then be de-greased. Grinding processes may also require coolant/lubricant to be applied. The ablation of the grinding wheel, a natural part of the process, leaves carbide granules that are a hazard in many products. Similarly, water cutting leaves garnet residues. Laser cutting involves only energy and gases and poses no risk of material contamination of the resulting parts.
Few production methods can come close in processing speed to laser cutting. The ability to cut a 40 mm steel sheet using a 12 kW oxygen-assisted laser provides speeds some 10x faster than a bandsaw and 50'100 times faster than wire cutting.
Laser cutting allows intricacy through the nature of the G-code movement control method of positioning and the small size of the applied energy hot spot. Features that are only weakly attached to the main body are cut without any application of force, so the process is essentially limited by material properties, rather than process capabilities.
Laser cutting is a flexible technology that can be adapted to cut widely different materials efficiently, including: acrylic and other polymers, stainless steel, mild steel, titanium, hastelloy, and tungsten. This versatility is increasing as technology develops. For example, dual frequency lasers can be applied to cut carbon fiber reinforced composites'one frequency for the fiber, one for the bonding agent.
Laser cutting finds application in many manufacturing industries because of the combination of versatility, high processing speeds, and precision. Sheet materials are key to production across most manufacturing industries. Applications of laser cutting across industries include: airframes, ships, medical implants, electronics, prototyping, and mass production.
Laser cutting disadvantages include: limitations on material thickness, harmful gases and fumes, high energy consumption, and upfront costs.
Most laser cutting machines sit in the <6 kW range. Their cut depth is limited to ~12 mm in metal thickness'and they accomplish that only slowly (~10 mm/s). It requires the largest and most powerful machines to reach the practical limits of cutting. However, similar limits apply to waterjet and wire erosion cutting. All three processes perform these deeper cuts faster than can otherwise be achieved.
While many materials'particularly metals'do not produce harmful gases in the cutting process, many polymers and some metals do. For example, PTFE and various fluoropolymers produce phosgene gas (which is incompatible with human environments) when heated to high temperatures. These materials require controlled atmosphere processing.
Laser cutting machines have a higher energy consumption rate than other cutting tools. A 3-axis CNC machine cutting out 40 mm steel plate blanks will consume around 1/10th of the power of a laser cutting machine extracting the same part. However, if the processing time is 1 minute on the laser cutter and 20 minutes on the CNC, the net power usage is 2:1 in favor of the laser cutter. Each part will have a different profile in this regard, but the differentials are rarely simple to analyze.
What are the advantages and disadvantages of fiber laser cutting machine
1. Good beam quality: the smaller the cutting line is, the higher the processing efficiency is and the better the processing quality is;
2. Fast cutting speed: the optical fiber laser cutting machine is twice of the equal power CO2 laser cutting machine;
3. High stability: Wuhan Ruike fiber laser, stable performance, the service life of key components can reach hours;
4. Electro-optic conversion efficiency is very high.Optical fiber laser cutting machine is about 30%, three times of CO2 laser cutting machine, energy saving and environmental protection;
5. Low operating cost: the power consumption of the whole machine is only 20-30% of that of the same CO2 laser cutting machine;
6. Low maintenance cost: optical fiber transmission, no reflector;Basically free of maintenance, can save a lot of maintenance costs;
7. Simple operation: optical fiber transmission, no need to adjust the optical path;After a simple training can be used, very convenient.
Compared with CO2 laser cutting machine, the biggest disadvantage of fiber laser cutting machine is that it is expensive. The price of a basic fiber laser cutting machine is usually more than 17,000 US dollars, which is often 3-4 times that of a CO2 laser cutting machine of the same size. Because the fiber slit is very thin, the gas consumption is very large (especially nitrogen cutting), and there will also be a part of the cost. In addition, the fiber laser cutting machine is difficult to cut high reflection materials such as aluminum plate and copper plate, the cutting speed is not obvious, and the cutting thickness is difficult to exceed 30mm.

Even with the advantages and disadvantages of the optical fiber laser cutting machine, the advantages of the optical fiber laser cutting machine are greater than the general disadvantages. Just a few years ago, such achievements were made. The research and development of fiber laser technology still have broader space for development. I believe in the future, metal laser cutting machine will bring us more technological surprises and processing breakthroughs!
If you want fast and accurate cutting, then fiber optic laser cutting machine is essential. Optical fiber laser cutting machine can cut steel, brass, aluminum, etc., without fear of machine damage.
The new technology produces a laser beam that is transmitted to the laser cutting head. Lasers transmit the heat of cutting metal to cut sheet metal with unmatched precision and quality.
The CNC laser cutting machine has excellent cutting quality and cutting materials such as titanium, brass, mild steel, copper, aluminum, stainless steel, etc. In the operation of the fiber laser, you can see the beam through the collimating lens with the help of optical configuration, and through the lens formed metal. It gives the material the desired shape and ensures that the material is properly trimmed.
Fiber laser cutting machine uses metal plate to process advertising trademarks, high/low voltage electrical cabinets, mechanical parts, kitchen utensils and automobiles, etc., to carry out efficient etching of materials, which adds significance to the aesthetic design of materials.
In addition, the laser cutting machine is simple to operate.All you need to do is follow the three-step approach:
Create a page in the graphics software and import the designs that you want to sculp or create your own custom designs.
Set your laser machine to send your design to the laser.Now, move to the print driver, select the laser parameters to use, or select the default material Settings from the database.
Finally, select your document, place the material on the machine, close the machine door, and continue cutting.
Laser cutting machine is involved in all walks of life. Due to business demand, some customers may need to cut 10mm thick carbon steel material. For such a thick material, many customers are still choosing flame cutting or CNC punch. However, the processed product has more burr and slower speed.
Which laser cutting machine is suitable for cutting 10mm carbon steel?
The 10mm thick carbon steel material for the traditional metal cutting equipment not only cannot meet the speed requirements, but also has a certain quality gap with the laser cutting machine. Fiber laser cutting machine, with its strong cutting ability, fast speed and high machining precision, has become the cutting equipment of sheet metal.In addition, optical fiber laser cutting machine can also according to the need to cut a variety of complex graphics, to meet the needs of various industries.
We can consider the following three aspects:
1. If you cut metal materials below 10mm for a long time, it is recommended to choose a W fiber laser cutting machine. This is a basic metal laser cutting machine, relatively cheap price and fast economic benefit.
2. If we often cut carbon steel of about 10mm, we suggest using a W fiber laser cutting machine. It can meet your needs for batch processing sheet metal.
3. When the cutting range of carbon steel material is greater than 10mm, it is recommended to use a W fiber laser cutting machine, which has a stronger cutting ability for thick sheet metal. Although the price will be higher, it will be more cost effective considering the long-term development of the business.
Fiber laser is a new kind of laser developed in the world. It outputs high energy density laser beam and focuses on the workpiece surface, which makes the surface irradiated by ultra-fine focus melt and vaporize instantaneously. The spot irradiation position is moved by the CNC mechanical system to realize automatic cutting. Compared with gas laser and solid laser, they have obvious advantages and have gradually developed into important application fields in high-precision laser processing, lidar system, space technology, laser medicine and other fields.
