What is Laser Cutting Machine?

Laser cutting machine uses focused high-power density laser beam to irradiate the work-piece, so that the irradiated material can melt and vaporize rapidly with the help of combustion or coaxial high-speed airflow, the high-speed airflow blows away the molten material, and then cuts the work-piece.

 


 

Why Replace Traditional Equipment with Laser Cutting Machine?

Flame cutting is the original traditional cutting method. It is mainly used to cut thick steel plates over 40mm in rough processing. Although it only requires a low investment, this technology is easy to lead to too large thermal deformation during cutting, too wide cutting slit, waste of materials, with slow processing speed.

 

Plasma cutting and fine plasma cutting are similar to flame cutting, and their accuracy and processing speed are much higher and faster than the latter one, becoming the main force of medium plate processing. The disadvantage is that the thermal deformation is too large when cutting thin steel plate and the slope is also large with a relatively high cost.

 

Laser cutting is both a technological revolution and a "processing center" in sheet metal processing. This technology boasts high flexibility, high cutting speed, high production efficiency and short production cycle, which has won a wide market for customers. In addition, it is able to avoid cutting force, deformation, and tool wear with good material adaptability. Whether it is simple or complex parts, it can be precisely and rapidly formed. Besides, with laser processing the finished products will have narrow cutting seam and good cutting quality. And laser cutter has a high degree of automation, simple operation, long effective life, and low labor intensity and no pollution. It can realize automatic cutting layout and nesting and improve material utilization rate, so as to achieve low production cost and good economic benefit

 

Advantages of Laser Cutting Machine:

1. High quality and low labor cost

Characterized by its non-contact processing, laser technology does not damage the work-piece with the products free of extrusion deformation and in good quality. And the processed products do not need to be polished manually, eliminating unnecessary processing procedures and optimizing the labor intensity of workers.

 

2. Reduced mold investment and production cost

By directly processing various work-pieces without mold, the laser cutting machine can help to avoid mold consumption and the costs of repairing and changing molds. In this way, a large number of molds and their production costs can be saved, which is especially suitable for processing large products.

 

3. High precision and high efficiency

Due to its precision, flexibility and efficiency, laser cutter is capable of processing various complicated work-pieces. With the finished cutting graphics being imported into the control system, the worker can set the size for cutting, which directly shortens the product processing and manufacturing cycle and effectively improves labor productivity.

 

4. Fast speed and optimized working environment

With fast working speed, stable working situation, low noise and no dust, laser cutting machine will not produce chemical substances harmful to the human body and the environment. It also protects workers from health threats and production sites from pollution, reducing investment and pollution and helping the optimization of the working environment complying with the trend of environmental protection.

 

5. Low maintenance cost and high cost performance

The maintenance of mechanical products is very expensive, while the laser cutting machine has stable performance which is durable and can work continuously.

 


 

Which Field can Metal Laser Cutting Machine Work in?

Over the past several decades, China has gradually become an international processing and manufacturing center. With the demand for metal processing is increasing, the complexity of the process is becoming higher and higher. In terms of precision, higher requirements are also put forward for sheet metal processing which is the main component of metal processing in industrial production activities, and is also an important process of forming sheet metal products. It is widely used in various fields, such as household appliances, instrument metal shells, road billboards, garbage cans, charging piles and car washing machines.

 

1. Automobile industry

Laser cutting machine processing technology is widely used in automobile safety system, body, chassis, interior trim, automobile electronic and electrical equipment, engine, gearbox, transmission shaft and cardan shaft, exhaust and fuel system, parts and other places. Laser cutting technology can simplify the processing steps of the body, shorten the manufacturing cycle and improve the cutting speed. At the same time, improve the quality of automobile processing to meet the processing needs of different models.

5. Kitchen utensils and household appliances industry

Household appliances and kitchen utensils are mainly made of metal sheets, with many visible parts and high quality requirements, so the processing technology is strictly required. In this industry, the laser cutting machine is helpful to cut the range hoods, metal cook-tops, pots and pans, electric fans, cabinets and so on. The cutting precision is extremely high, the cutting seam is extremely narrow, and the speed is extremely fast, thus improving the yield.

How to Choose a Laser Cutting Machine?

There are many factors having an impact on your choice of a laser cutting machine.

 

Primarily, you should consider which industry are you work in and how thick the products you need to cut. Generally speaking, laser cutting is suitable for carbon steel below 12mm and stainless steel below 6mm in many industries, such as automobile, sheet metal, coiling blanking and so on. However, the limited cutting thickness of the laser cutting machine must be reserved! For example, the maximum cutting thickness of a laser cutting machine is 16mm, which means that the laser cutting machine can cut 16mm at most. But if the laser cutting machine cuts 16mm for a long time, the service life of this machine will be damaged. There is a difference between the maximum cutting thickness and the regular cutting thickness of the laser cutting machine.

 

Secondly, the breadth should be considered. At present, the mainstream cutting format in the market is 3015 (3m * 1.5m). The cutting format of the laser cutting machine is generally customized by the manufacturer according to the needs of customers.

 

Thirdly, rag control is also significant, which is the most concern of customers. Generally, the materials cut by the laser cutting machine will somewhat form the burr, which is mainly determined by the cutting thickness of the laser cutting machine and the gas used by the it. In most cases there is no burr when the thickness is below 4mm. As for the gas choice, nitrogen is the best, oxygen is the second, and air is the worst. Metal laser cutting will have the best performance on the thin plate. Of course, with the popularization of high-power laser cutting machines and the continuous development and improvement of equipment, it is also good at thick plates cutting now.

 

From the perspective of the configuration of each part of the laser cutting machine, what aspects should be considered?

1. Laser

Laser is the most important part in a laser cutting machine. The longer the service life of a good brand, the higher the stability. Choosing a good laser can make the life of the equipment longer.

 

2. Engraving head

The cutting head is generally composed of a nozzle, a focus lens and a focus tracking system. Good cutting head can improve cutting quality and obtain better cutting products.

 

3. Operating system

The main function of the operating system is to process the graphics and image files designed by the user and finally make the control instructions for driving the motor and laser, so as to complete complex processing. A good operating system has simpler interactive pages and better nesting software, thus simplifying operation and saving materials.

 

4. Refrigerator

A refrigerator achieves refrigeration effect through steam compression or absorption cycle. There are many brands of water chillers. Good brands can achieve stable cooling effect for a long time, so that high load laser cutting machines can also operate within a stable temperature range.
