Five maintenance tips for fiber laser cutting machines

Five maintenance tips for fiber laser cutting machines

With the rapid development of domestic automotive, machinery, steel, large equipment and other industries, the demand for fiber laser cutting machines in the market has increased year by year. The fiber laser cutting machine has gradually replaced the traditional CNC punching machine and flame cutting in the metal sheet processing industry due to its fast cutting speed and high precision.

With the changing needs of users, fiber laser cutting machine has become an indispensable processing equipment. But in daily operation, many users do not know much about the maintenance of fiber laser cutting machine.


Today, I have arranged 5 maintenance techniques for you. I hope you will be more helpful when using fiber laser cutting machine.

1. Regularly clean all rails of laser cutting machine and exclude dust and other debris. Always clean motors and guideways and add lubricating oil. The machine can walk better when moving, effectively ensuring the cutting quality of laser cutting machine.

2. Check the steel belt of the laser cutting machine regularly. Otherwise, if there is a problem in operation, it may lead to injury.

3. Use a vacuum cleaner once a week to suck out the dust and dirt in the machine. All electrical cabinets should be dustproof and dustproof.

4. The double focal length laser cutting head is a fragile material on the laser cutting machine. It will damage the laser cutting head for a long time.

5. Check the straightness of the laser cutting machine track and the perpendicularity of the machine every three months. It is found that it should be debugged in time when it is abnormal, otherwise the error will affect the cutting quality.

What are the commonly used engineering materials for metal laser cutter?

Although almost all metal materials have high reflectance to the infrared wave energy at room temperature, the CO2 laser, which is in the far infrared 10.6um beam, has been successfully applied to the laser cutting practice of many metals. The initial absorptivity of metal to 10.6um laser beam is only 0.5%~10%. However, when a focused laser beam with a power density of more than 106w/cm2 reaches the metal surface, it can melt the surface rapidly within microsecond time. The absorption rate of most metals in molten state increases rapidly, generally increasing 60%~80%.

What are the common engineering materials for cutting metal laser cutting machines?

(1) Carbon steel. Modern laser cutting equipment can cut carbon steel plates with a maximum thickness of 20MM. The cutting seam of carbon steel can be controlled in a satisfactory width range by oxidizing and melting cutting mechanism, and the slit can be narrowed to about 0.1MM.

(2) Stainless steel. Laser cutting machine is an effective processing tool for manufacturing industry using stainless steel sheet as the main component. Under strict control of heat input in laser cutting process, the heat affected zone of trimming can be restricted to be very small. Therefore, it is very effective to maintain good corrosion resistance of such materials.

(3) Alloy steel. Most alloy structural steels and alloy tool steels can obtain good edge cutting quality by means of laser cutting machine. Even with some high strength materials, straight and sticky slag trimming can be obtained as long as the process parameters are properly controlled. However, for high speed tool steels and hot die steels containing tungsten, there will be erosion and slag sticking during laser cutting.

(4) Aluminum and alloy. Aluminum cutting is a melting and cutting mechanism. Auxiliary gas is used to blow away the molten products from the cutting area. The better quality of the tangent is usually obtained. For some aluminum alloys, it is necessary to prevent the occurrence of intergranular micro cracks on the surface of the slit.

(5) Copper and alloy. Pure copper (copper) can not be cut by CO2 laser beam because of its high reflectivity. Brass (copper alloy) uses higher laser power and auxiliary gas uses air or oxygen to cut thinner plates.

(6) Titanium and alloy. Pure titanium can be well coupled to focus the heat energy transferred by the laser beam. When the auxiliary gas is used in oxygen, the chemical reaction is intense and the cutting speed is fast. However, it is easy to form oxide layer on the side of the cut. In order to be safe, it is better to use air as auxiliary gas to ensure the quality of cutting. The laser cutting quality of titanium alloy commonly used in aircraft manufacturing industry is better. Although there is a little slag on the bottom of the slit, it is easy to remove.

(7) Nickel alloy. Nickel based alloys, also known as superalloys, have a wide variety of varieties. Most of them can be oxidized and melted.

In addition to metal laser cutter, our official website also provides CO2 laser cutting machine and fiber laser cutting machine.

What does the fiber laser cutting machine use to do?

The structure of fiber laser cutting machine is composed of worktable, fiber laser and console. It belongs to the new generation of large-scale processing equipment. And the traditional CNC punching machine, flame cutting, plasma cutting machine belongs to the same machine tool. At present, fiber laser cutting machine is favored by many users in the industry due to its advantages of fast cutting speed, low maintenance cost and high cutting quality.

So what does fiber laser cutting machine do? How does it work?

 

In a simple way, the laser of a fiber laser cutting machine translates energy into a laser beam, illuminates the surface of the metal material through the cutting head, and absorbs the heat of the laser beam to a melting boiling point in a moment, and forms the cutting seam to form the cutting effect according to the position of the computer designed pattern program to move the cutting head.

Fiber laser cutting machine has excellent quality for stainless steel, carbon steel, iron plate, alloy steel, aluminum, copper, galvanized sheet, titanium alloy and other metal materials. At present, the big bulk has been widely recognized in sheet metal processing, chassis cabinets, kitchen utensils manufacturing, auto parts, metal handicrafts, machinery manufacturing and other industries.

What are the advantages of a fiber laser cutting machine?

1. The cutting quality is good. The surface of the sheet metal produced by the fiber laser cutting machine is smooth and smooth without burrs.

2. The cutting speed is fast. Stainless steel processed with auxiliary gas for processing 1mm can be cut 35 meters per minute.

3. The material is not deformed. Fiber laser cutting machine works through the principle of laser beam irradiating materials. There is no contact with the workpiece itself, so the material has no deformation.

4. The operation is simple and convenient. The operation of fiber laser cutting machine only needs to design the pattern that needs to be processed in the control software, and it can run automatically without manual operation.

5. The cost of maintenance is low. Because there is no need for die and no wear at work, the maintenance cost of fiber laser cutting machine is low.
