What is a laser cutter used for?

Laser cutters are widely used, especially in industrial manufacturing. Perfectly fast cuts for most metal materials, regardless of hardness.

Processing industry

Laser processing technology has the advantages of a wide range of processing materials, high processing efficiency, high processing accuracy, small workpiece deformation, clean and pollution-free, and is gradually replacing traditional processing techniques in the fields of material cutting, welding, additive manufacturing, and inkjet marking. And it is widely used in material processing and lithography, communication and optical storage, instruments and sensors, medical treatment and beauty, scientific research and military, entertainment and printing, and other fields.

In addition, laser processing numerical control industrial software is combined with computer numerical control technology and mechanical automation technology to achieve precise processing of materials of different materials, shapes and volumes. After long-term technology accumulation and industrial application practice, a complete industrial chain system has been formed in the laser processing industry. All kinds of sheet metal products in life may come from the masterpieces of laser cutters. Below I will introduce the industries where laser cutters are widely used.

1. Kitchenware industry

Kitchenware is one of the essential metal products in our daily life. The traditional processing methods in the kitchenware manufacturing industry are facing difficulties such as low work efficiency, large consumption of molds, and high cost of use. Laser cutters have fast cutting speed and high precision, which improves processing efficiency, and can realize customization and personalized product development, solve the problems of kitchen utensil manufacturers, and have won the recognition of kitchen utensil manufacturers.

2. Automobile manufacturing industry

There are also many precision parts and materials in automobiles, such as automobile brake pads, etc. To improve the safety of automobiles, it is necessary to ensure cutting accuracy. The traditional manual method is difficult to achieve accuracy, and secondly, the efficiency is low. Laser cutting can be used for faster batch processing. High efficiency, no burr, one-time molding and other advantages, these are the reasons why laser cutting machines are widely used in the automotive industry.

3. Fitness equipment industry

The diversity of fitness equipment also puts forward high requirements for processing. Various specifications and shapes make traditional processing complicated and inefficient. Laser cutting has high flexibility. It can customize flexible processing for different pipes and plates. After processing, the finished product is smooth and burr-free, and there's no need for secondary processing. The quality and efficiency are greatly improved compared with traditional processes.

4. Advertising industry

Advertising Traditional processing equipment generally process advertising fonts. Due to the inaccuracy of processing and unsatisfactory cutting surface, the probability of rework is quite high. High-precision laser cutting technology does not require secondary work, which greatly improves work efficiency and saves enterprise costs.

5. Sheet metal processing industry

With the rapid development of sheet metal processing technology, traditional sheet metal cutting equipment can no longer meet the current process and cutting shape requirements. Laser cutting has gradually replaced traditional equipment with its advantages of high flexibility and fast cutting speed. Fiber laser cutting machines' wide application in sheet metal processing is an inevitable trend.

6. Chassis cabinet industry

The power distribution cabinets and filing cabinets we see in our life are all products of standardized production of thin plates, which have high requirements for efficiency. However, it is relatively suitable to use laser cutting machines with four or six stations, and the efficiency is high at the same time. , Double-layer cutting can also be achieved for specific plates.

7. Agricultural machinery industry

With the continuous development of agriculture, the types of agricultural machinery products tend to be diversified and specialized, and at the same time, new requirements are put forward for the manufacture of agricultural machinery products. The advanced laser processing technology, drawing system and numerical control technology of laser cutters not only reduce the production cost of agricultural machinery equipment but also improve economic benefits.

8. Shipbuilding industry

In the field of shipbuilding, laser-cut marine steel plates have good slit quality, good verticality of the incision surface, no dross, thin oxide layer, smooth surface, no secondary processing, can be directly welded, and the thermal deformation is small, curve cutting High precision, less working hours, and could realize barrier-free cutting of high-strength ship plates.

9. Automobile industry

In the automotive industry, some accessories such as car doors, car exhaust pipes, etc. will leave some redundant corners or burrs after being processed. If they are processed manually or traditionally, it is difficult to guarantee accuracy and efficiency. If the laser cutting machine is used for processing, the corners and burrs can be easily solved in batches.

As one of the most intelligent industries at present, automobile manufacturing has integrated a variety of production processes, and laser, as one of the most important technologies, has achieved up to 70% of the intelligent production of accessories.

10. Aerospace

Laser manufacturing technology is an important part of aerospace manufacturing technology. Laser cutting processing technology has been widely used in parts, components and other components of aircraft and aerospace rockets.

11. Construction machinery industry

Generally speaking, the plates used in the construction machinery industry are mostly medium-thick plates. Bevel laser cutting can solve the problem of blanking and beveling at one time. It has the advantages of high precision, fast speed, high material utilization rate, and reduced labor costs.

In addition to the above-mentioned industries, laser cutting is used in iron towers, curtain walls, elevators, steel structures, medical equipment, lifting machinery and other industries.

Laser cutting materials

1. Structural steel

This material will have better results when cut with oxygen. When oxygen is used as the processing gas, the cutting edge will oxidize slightly. For plates up to 4mm thick, nitrogen can be used as the processing gas for high-pressure cutting. In this case, the cutting edge will not be oxidized. For plates with a thickness of more than 10mm, better results can be obtained by using a special plate for the laser and oiling the surface of the workpiece during processing.

2. Stainless steel

Oxygen can be used where oxidation of the cutting end is acceptable; nitrogen is used to obtain an oxidation-free and burr-free edge, and no further treatment is required. Coating oil film on the surface of the plate will get a better perforation effect without reducing the processing quality.

3. Aluminum

With high reflectivity and thermal conductivity, aluminum materials up to 6mm thick can be cut, depending on the alloy type and laser capability. When cutting with oxygen, the cutting surface is rough and hard. When nitrogen is used, the cut surface is smooth. Pure aluminum is very difficult to cut because of its high purity, and it can only be cut when a "reflective absorption" device is installed on the system. Otherwise, reflections could destroy the optical components.

4. Titanium

Titanium plates are cut with argon and nitrogen,which act as processing gases. Other parameters can refer to nickel-chromium steel.

5. Copper and brass

Both materials have high reflectivity and very good thermal conductivity. Brass with a thickness of less than 1mm can be cut with nitrogen, copper with a thickness of less than 2mm can be cut, and the processing gas must be oxygen. Copper and brass can only be cut if the system is equipped with a protective device. Otherwise, reflections could destroy the laser source.
