Metal laser cutter is a type of CNC laser cutting machine for sheet metals, metal plates, metal profiles, metal tubes and metal pipes, which is the best metal cutting solution for metal fabricator.

YAG laser, CO2 laser machine, fiber laser can all be used to cut sheet metal. But the cutting effect, cutting speed, and machine price of the three have a big gap.

YAG is no longer a commonly used metal cutting laser. I will not introduce it in detail here. Next, we will mainly compare the difference between CO2 metal laser cutter and fiber metal laser cutter in cutting metal sheets:

  1. Different luminescent media

In the CO2 metal laser cutting machine, gas is the medium that generates the laser beam, and the beam is transmitted through the reflector. Fiber lasers are transmitted through diodes and fiber optic cables, and multiple diode pumps produce laser beams, which are then transmitted to the laser cutting head through fiber optic cables, instead of transmitting the beams through mirrors.

  1. The appearance of laser metal laser cutter  is more compact

Due to the different laser transmission structure, the fiber metal laser cutting machine of the same power is more compact than the CO2 laser metal cutter, which saves the space of the plant and is more suitable for the application of the old warehouse.

  1. The electro-optical conversion efficiency of the metal fiber laser cutting machine is relatively high

The metal fiber laser cutting machine adopts a complete solid-state digital module and a single fiber laser design. The electro-optical conversion efficiency is higher than that of carbon dioxide metal laser cutter. The actual total utilization rate of each power supply of the CO2 laser cutting machine is about 8%~10%. The total utilization rate is about 25% to 30%. The total energy consumption of the fiber laser metal cutting system is 3 to 5 times lower than that of the carbon dioxide cutting system, which is increased by more than 86%.

  1. The processing effect of metal fiber laser cutting machine is better

Metal laser cutter fiber lasers have short-wavelength characteristics, which improve the absorption of light beams by cutting materials, making it possible to cut non-conductive materials such as brass. When the cutting metal material thickness reaches 6mm, the cutting speed of a 1500W fiber laser cutting machine is equivalent to that of a 3000W carbon dioxide laser cutting machine.

Besides, the fiber metal laser cutting machine also have below advantage:

  1. High precision: suitable for cutting precision parts and various craft characters and fine cutting.
  2. Fast speed: more than 100 times that of wire cutting.
  3. The heat-affected zone is small and not easy to deform. The cutting seam is smooth and beautiful, without subsequent processing.
  4. High cost performance of metal laser cutter
  5. The use cost of metal laser cutter is very low
  6. The follow-up maintenance cost is very low
  7. Stable performance, which can ensure continuous production.

Above all, Laser cutting equipment is mainly divided into fiber laser cutting machine, YAG laser cutting machine and CO2 laser cutting machine. All three types of machines can be used for metal laser cutter, but we recommend the fiber laser cutting machine for metal cutting.

Laser cutting metal machines are most commonly used in the production of 3 products:

(1) Sheet metal label

A common use for metal laser cutter is to create laser-cut sheet metal labels. Many manufacturers use these labels to distinguish similar parts. With these self-made labels, products with similar appearance but different uses can be better visually identified.

(2) Engraving sheet metal

Set the laser cutting machine to a lower power and start the laser cutting machine to leave smooth and regular grooves on the surface of the metal plate. Laser engraving enables manufacturers to leave delicate but unique marks on sheet metal products.

(3) Cutting parts

Laser cutting makes small cuts in the metal plate. Then these small cuts made are used in industries with high requirements for refinement.

The metal cutting machine can cut: stainless steel plate, aluminum plate, carbon steel plate, aluminum alloy plate, copper plate and other plate metals.

According to different laser power, the laser cutter machine can cut metal plates of different thicknesses.

E.g:

Metal Laser cutter with 1000W power: 1mm-6mm stainless steel, 1-12mm carbon steel, 1mm-4mm aluminum and brass

1500W power metal laser cutting machine: 1mm-8mm stainless steel, 1-16mm carbon steel, 1mm-5mm aluminum and brass

2000W power fiber metal laser cutting machine: 1mm-8mm stainless steel, 1-20mm carbon steel, 1mm-6mm aluminum and brass

Metal Laser Cutting machine with 1000W power: 1mm-10mm stainless steel, 1-20mm carbon steel, 1mm-8mm aluminum and brass

The working size of the metal laser cutter can be customized according to the customer’s sheet size. Usually

the model is divided according to the working table of the machine, such as: TPF-1530, 1500mm*3000mm

TPF-2060, 2000MM*6000mm, etc.

 How much does a steel laser cutting machine cost? There are many factors that affect the price of the steel laser cutter machine. We only list the points that customers will ignore to list: accessories, laser source, bed, and service.

Steel laser cutting machine accessories, a laser cutting machine uses different parts, such as lasers, motors, laser lenses, laser tubes, control systems, all of which will affect the price of the laser cutting machine.

Accessories:

(1) The motor directly affects the accuracy of the steel laser cutting machine. The cost of the famous brand motor is different from that of the ordinary brand motor,  and the accuracy of the laser cutting machine will also be different.

(2) The guide rail rack directly affects all the operating conditions of the steel laser machine. Good brands have high prices, life span and smoothness are relatively much better, and vice versa.

Laser source:

A laser is the core of a light laser cutting machine. There are many brand lasers on the market, and the effect and service life are naturally very similar, so the price gap is also very large.

After-sales service guarantee (full service can ensure the safety and timely maintenance of user equipment): Some companies think that they are pursuing the maximization of steel laser machine sales and do not pay attention to after-sales problems after steel cutter machine sales. If a company invests heavily in the after-sales department, then Customers who buy metal laser cutting machines in this company will be the happiest, because the quality of a company’s after-sales department directly reflects the company’s responsibility to customers. It is conceivable that the price of the machine will also include this under the premise of customer consideration. cost.

Machine bed: In order to reduce the cost, some manufacturers of the bed and casing of the light laser cutting machine use thin iron sheet to make the casing. Some users usually don’t see them. But after a long time, the frame will be deformed, which will affect the cutting accuracy of the laser cutting machine. A good steel laser cutting machine should adopt a frame structure, welded with high-quality steel, and use high-quality cold-rolled steel to make the shell. When the user buys the machine, he can see whether the quality can be seen through the frame structure, the thickness and strength of the shell iron.

Those who are familiar with laser cutting machines lament that the configuration of laser cutter machine nowadays has increased so much, and the price has dropped compared to a few years ago. However, some people say, don’t be fooled by those external things, new years ago. The reliability of the equipment and maintenance services are convenient and affordable.

In my opinion, the current metal cutting machine market is complex and there are many vicious competitions. If you want to purchase a perfect metal laser cutter machine, you might as well take the above points as a reference.

Metal laser cutter machine have a widely useage. In rail locomotives, aerospace, automotive industry parts manufacturing, car body processing, bogie manufacturing, as well as precision medical beauty equipment processing, steel and wood furniture, machinery manufacturing, household appliances and kitchenware, fitness equipment manufacturing, laser cutting machines play an important role Role. In short, wherever metal materials need to be cut, there will be laser cutting machines.

CO2 laser cutting machines are usually used to cut plastic, foam, wood, glass, textiles or mild steel. The CO2 laser cannot cut highly reflective metals such as copper or brass. A more powerful fiber laser cutting machine is used to cut metal plates, steel, stainless steel, aluminum, copper, brass, galvanized sheets,carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, aluminized zinc sheet, pickling sheet, copper, silver, gold, titanium and other metal plates and pipes as well as other high-reflective materials

In order to choose the right metal laser cutter machine according to your requirements, you must first choose according to the main characteristics of the material to be cut. To give a few examples, metal steel cutting machines, plastic cutting machines, fabric cutting machines, and wood cutting machines do not all use the same technology.

 

You also need to choose a machine according to the thickness to be cut, and a worktable with a suitable size. Finally, you must choose the cutting technology based on the required precision, cutting quality, and required productivity. Of course, your budget is also very important. For example, both the Co2 laser machine and the fiber laser cutting machine can cut metal, but the cost of the two machines is quite different.

In the process of cutting thick metal plates, the laser metal cutting speed will be significantly reduced, and the repeatability of the incision is not good, and it cannot compete with traditional technology.

The cutting section that is often encountered when processing medium and heavy steel plates. Such cutting is not only questionable in quality, but also accompanied by overburning and serious sticking, so that it does not reflect the value of high-priced laser processing machines from other cutting methods . However, if a low-power pulse is used for perforation, the time is very long (12 seconds), resulting in a decrease in cutting efficiency and an increase in unit cost.

Perforation time accounts for a large proportion in the processing of thick plates cutting. Various metal laser cutter manufacturers have developed rapid perforation technology. The most representative one is high-energy perforation. The advantage of this method is fast speed. But the defect is that the huge energy star injected during the perforation increases the temperature of the sheet and affects the subsequent overall cutting process, and affects the processing of small shapes.

For carbon steel, an important factor in improving the cutting section is to control the heat input to the plate and to ensure the full combustion of the laser-irradiated part. For stainless steel, the important factors to improve the cutting section are the improvement of the beam (improving the depth of focus) and the effective use of auxiliary gas.
