Inquire

I want to buy a fiber laser cutting machine, how can I buy it? How much does it cost to buy a fiber laser cutting machine? How does it work? What is the specific use? Before buying a laser cutting machine, many friends were confused in one way or another? Today, the sales manager of Leapion Laser came to have a specific chat with you, how to buy a cost-effective fiber laser cutting machine within the budget.

First of all, what is a fiber laser cutting machine?

As the name suggests, the fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as the light source. The fiber laser can output a high-energy density laser beam, which is concentrated on the surface of the workpiece through the optical path system, so that the area irradiated by the ultra-fine focus spot on the workpiece is instantly melted and vaporized. At the same time, the high-pressure gas coaxial with the beam will melt or vaporize The metal blows away. Through the numerical control mechanical system, to move the spot irradiation position to realize automatic cutting.

Second, what is the function of the fiber laser cutting machine?

1. Fiber laser cutting can cut various metal materials:

For example: stainless steel, 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 pipe cutting.

2. The application industry of fiber laser cutting machine is very extensive:

For example: used in sheet metal processing, aviation, aerospace, electronics, electrical appliances, subway accessories, automobiles, food machinery, textile machinery, engineering machinery, precision accessories, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration , Advertising, metal external processing, kitchenware processing and other manufacturing and processing industries. It is one of the necessary equipment for many enterprises.

Fiber laser cutting machine can be used for plane cutting and bevel cutting. In addition, the edges of the cut material are neat and smooth, which is suitable for high-precision cutting processing such as metal plates, and the robot arm can also perform three-dimensional cutting.

Third, how is the cutting quality of the fiber laser cutting machine?

1. Cutting accuracy is a key factor in determining cutting quality. Generally speaking, the cutting quality of optical fiber cutting machine can be measured by the following 6 standards:

A. Cutting surface roughness

B. The slag size of the incision

C. Cutting edge perpendicularity and inclination

D. Cut edge fillet size

E. Drag after stripes

F. Flatness

2. Cutting advantages of fiber laser cutting machine:

A. High cutting precision:

The positioning accuracy of the laser cutting machine is 0.05 mm, and the repeat positioning accuracy is 0.03 mm.

B. Smooth cutting surface:

There is no burr on the cutting surface, and the surface roughness of the cut is generally controlled within Ra6.5.

C. The cutting machine is fast:

The cutting speed can reach 10m/min, and the maximum positioning speed can reach 30m/min. It is much faster than the wire cutting speed. The cutting speed is twice that of the same power CO2 laser cutting machine.

D. Narrow slit:

The laser beam is focused into a small spot, so that the focal point reaches a high power density, the material is quickly heated to the degree of vaporization, and evaporates to form a hole. With the relative linear movement of the light beam and the material, the hole continuously forms a slit with a very narrow width. The width of the slit is generally 0.10-0.20mm.

E. High cutting quality:

The laser cutting head will not touch the surface of the material and will not damage the workpiece. In addition, laser processing is flexible, can process arbitrary graphics, and can cut pipes and other profiles.

F. Very low cost of use:

The electro-optical conversion efficiency of the optical fiber is high, and the power consumption of the whole machine is lower than that of the CO2, which saves the production cost.

G. Very low maintenance cost:

Compared with the CO2 laser cutting machine, the fiber cutting machine has no laser working gas, optical fiber transmission, and no reflective lens; it can save a lot of maintenance costs.

H. Convenient product operation and maintenance:

Optical fiber transmission, no need to adjust the optical path. Small size.

Fourth, how to use and maintain the fiber laser cutting machine:

The main daily maintenance parts are: cooling system (to ensure constant temperature effect), dust removal system (to ensure dust removal effect), light path system (to ensure beam quality), and transmission system (focus on ensuring normal operation).

1. Chiller maintenance

As the cooling equipment for fiber laser cutting machine, the water chiller ensures the normal operation of the fiber laser cutting machine at a constant temperature. Pay attention to the water temperature when working for a long time. It is recommended that the water temperature be below 35 degrees; in winter, the circulating water should be prevented from freezing to prevent freezing and cracking. The cooling effect is generally replaced once a month or so.

2. Dust prevention and dust removal maintenance

Use a vacuum cleaner to remove dust and dirt from the machine once a week, and all electrical cabinets should be closed to prevent dust. Especially for the case of fiber laser, pay attention to keep the case closed to prevent the high temperature and humidity from outside from entering the case.

3. Maintenance of drive rail

Each guide rail rack needs to be cleaned regularly to remove dust and other debris, to ensure that the equipment is normal, the rack must be wiped frequently and lubricated to ensure lubrication without debris.

4. Maintenance of light path system

Before starting up, check whether there is water leakage in the external light path circulating water circuit. Liquid leakage must be dealt with in time, otherwise it will affect the life of the optical lens. After the device has been running for a period of time, some dust will stick to the surface of the lens. This dust will greatly affect the reflectance of the lens and the transmittance of the lens, which will reduce the power of the laser. At this time, it is necessary to clean the lens. The dust. Ensure beam quality.

5. Other aspects

A. Check the steel belt frequently to ensure that the steel belt is tight. At an interval of 6 months, regularly check the straightness of the track and the verticality of the machine, and if it is found to be abnormal, it will be maintained and debugged in time.

B. After entering a new part program, test and check its operation.

In short, the operator must be trained, familiar with the structure and performance of the equipment, master the operating system knowledge and comply with the safety rules of the cutting machine. Start the laser strictly in accordance with the laser startup procedure. Then follow the rules of use to ensure safety.
