A comprehensive analysis of technology characteristic of laser cutting machine

A comprehensive analysis of technology characteristic of laser cutting machine

With the development of laser technology and mature, laser equipment has been widely application in all walks of life, such as laser marking machine, laser welding machine, laser drilling machine and laser cutting machine, and so on, especially CNC laser cutting machinery and equipment in recent years rapid development, is widely used in sheet metal, metal products, steel structure, precision machinery, auto parts, glasses, jewelry, nameplate, advertisement, arts and crafts, electronics, toys, packaging and other industries. Compared with other cutting equipment, CNC laser cutting machine is mainly reflected in the following aspects:

1, with high cutting speed, cutting quality is good, high precision;      
2, cut line is narrow, the cutting surface is smooth, does not damage the work piece;          
3, not affected by the shape of the workpiece, the material is not affected by the hardness;          
4, in addition to the processing of metal materials, but also for non metal cutting processing;          
5, saving investment, saving materials, more effective cost savings;      
6, the operation is simple, safe, stable performance, improve the speed of new product development, with a wide range of adaptability and flexibility.

Mechanical structure of metal CNC laser cutting machine is the most important part, not only most of the components are installed in the rack, and also the work gravity and acceleration and deceleration during the full impact loads.

CNC laser cutting machine design and development work including:

1, determine the CNC laser cutting equipment in a variety of conditions and the environment of fast, high precision, stable operation of the conditions.       2, according to the functional requirements of the frame structure, parameters, combined with the structural characteristics of the laser cutting machine, the establishment of the corresponding dynamic model.          
3, the structure and parameters of the frame are studied, the influence of the parameters on the static and dynamic stiffness and thermal stability of the frame are studied, and the theoretical basis for the design of the frame is provided. 4, determine the frame and other parts of the mutual coupling relationship

Therefore, CNC metal cutting machine designed in how to arrange the metals to reduce weight, increase body stiffness, reduce the effects of temperature change on accuracy, it is necessary to focus on the problems in the design process.
Therefore, in CNC metal cutting machine design how reasonable layout of metal, reduce weight, improve the body stiffness, reduce the influence of temperature change on the accuracy, is should be focus on the problem of the design process.
In the metal cutting laser circuit, there is a strong interference between analog signal and digital signal problem. Photoelectric isolation circuit is in electrical isolation to light for coal medium of transmission signal, the input and output circuit can isolate. So it can effectively suppress noise in the system, to clear the earth loop interference, responds faster, long service life, small volume, shock resistance etc. the benefits the in the strong - weak interface, especially in microcomputer system of backward and to the channel obtained widely application.

Photoelectric coupler has three characteristics:          
1, the signal is transmitted to take the form of electric light electricity, the light emitting part and the light receiving part are not in contact, which can avoid the feedback and the interference of the output end to the input end;     2, the ability to suppress noise interference;          
3, with a durable, high reliability and high speed and other advantages, the response time is generally within a few, the response time of high-speed optoelectronic coupler and some even less than 10ns.
Therefore, in the numerical control laser cutting machine system circuit design, should pay attention to the isolation of the input signal circuit and SCM connection. Here, the use of photoelectric coupling is the most commonly used method.
In the industrial manufacturing system of heavy metal processing industry, a lot of metal materials, no matter what kind of hardness it is, can be carried out without deformation cutting. Of course, for high reflectivity materials, such as gold, silver, copper and aluminum alloys, they are also good heat transfer conductor, so the laser cutting machine is difficult, and even can not be cut.
In spite of the laser cutting machine specific technology was a huge advantage, but as a high-tech equipment to use laser cutting machine to achieve the ideal cutting and processing effect, must also master the processing technical parameters and operation processes. Especially in the metal laser cutting machine cutting process, to select the appropriate cutting speed, or may cause some undesirable cutting results, mainly in the following:
1, when the laser cutting speed is too fast, it will cause the following adverse results:          
①.Method of cutting, spark spraying;          
②.The cutting surface is inclined to the lines, and the lower part of the production of molten stains;          
③.Cause the whole section is rough, but no melt stain is produced;
2, on the contrary, when the laser cutting speed is too slow, it will cause:   ①.Melting condition, the cutting surface is rough.          
②.The slit width, in sharp parts of the whole.          
③.Affect the cutting efficiency.
Therefore, in order to make the laser cutting machine equipment to better play its cutting function, you can cut the spark from the laser equipment to determine whether the feed rate is suitable:          
1, if the spark from the top down, it indicates that cutting speed is appropriate;          
2, if the spark back tilt, it indicates that the feed rate is too fast;       3, if the spark is not diffusion and less, together, it indicates that the speed is too slow.          
Most organic and inorganic materials can be used as laser cutting machine. Compared with other traditional cutting methods, laser cutting has obvious advantages compared with other traditional methods. Laser cutting machine has the characteristics of narrow slit, small deformation of the workpiece and high speed, high efficiency, low cost, safe operation, stable performance and so on.

Laser cutting machine cutting 7 types different metal materials

Laser cutting machine cutting 7 types different metal materials

Metal on the initiation of 10.6 um laser beam absorption rate is only from 0.5% ~ 10%, however, when with a power density of more than 106w/cm2 focused laser beam irradiation to the metal surface, but it can in the microsecond time soon so that the surface begins to melt. The absorption rate of most metals in the molten state has risen sharply, which is generally improved by 60%~80%.

1.Titanium and its alloys.          

Pure titanium can be very good coupling focused laser beam transformation of heat energy, auxiliary gas oxygen chemical reaction, cutting speed, but easy to generate oxide layer on the cut edge, not careful will cause too much. For the sake of safety, the use of air as an auxiliary gas is better, to ensure the quality of cutting.          
Aircraft manufacturing industry commonly used titanium alloy laser cutting quality is better, although there will be a little sticky residue at the bottom, but it is easy to clean up.

2.Nickel alloy.          

Nickel based alloy, also known as super alloy, a lot of variety. Most of them can be carried out to melt and cut.

3.Carbon steel.          

Modern laser cutting machine can cut carbon steel plate with the maximum thickness of up to 20MM, the use of oxidation and melting cutting mechanism to cut carbon steel cutting seam can be controlled in a wide range of satisfaction, the thin sheet of its cut can be narrow to about 0.1MM.

4.Stainless steel.          

Laser cutting is an effective tool for the manufacture of the stainless steel sheet as the main component. In the strict control of the laser cutting process of the heat input measures can be restricted to the edge of the heat affected zone is very small, so that it is very effective to maintain the good corrosion resistance of such materials.

5.Alloy steel.         

The majority of alloy structural steel and alloy tool steel using laser cutting method to obtain good cutting quality. Even some of the high strength materials, as long as the process parameters are properly controlled, can get straight, non stick slag cutting edge. However, for high speed tool steel and hot die steel, laser cutting machine will have the phenomenon of corrosion and slag.

6.Aluminium and alloys.          

Aluminum cutting is a melting laser cutting mechanism, which is mainly used to blow away the molten product from the cutting area. For some aluminum alloys, it should be noted that the prevention of micro cracks on the surface of the cutting seam is noticed.

7.Copper and alloys.         

Copper (copper) because the reflectivity is too high, basically can not use CO2 laser beam cutting. Brass (Red copper) using a higher laser power, auxiliary gas using air or oxygen, can be a thin sheet of cutting.

Effect of laser output power on laser cutting

Effect of laser output power on laser cutting 
When using laser cutting machine,the laser output power is a parameter that has a direct relation with the melting ability of the processed. For getting good effect of cutting,we need increase the output power in order to improve the processing ability.

Improve processing capacity:
1, improve the laser cutting speed.          
2, increase the thickness of the processing plate.          
3, processing of aluminum, copper and other high reflection spectral reflectance factor.          
4, zoom lens from the short focal length lens.          
5, the focus of the location from the surface of the processed material changes.

We can determine whether the use of the processing conditions of the output energy is appropriate, according to the processing of the cutting surface and machining in the case of the spark. When the output power is much larger than the standard value, the thermal effect of the incision increases, and the melting loss occurs at the corner. And cut the noodles to become thick, from the upper to the lower part of the vertical.
If the output power value is far less than the standard value, the lower part of the cut is significantly thicker, become the state of digging into. And with the increase of the amount of adhesion of slag, it is difficult to remove. Mars is lagging in the cutting process in the opposite direction in the cutting process.
Suitable for the processing of the output conditions exist within a certain range, the thinner the thickness of the processing board, the wider the range of output conditions. Output processing in proper conditions, the cutting surface streak fine, lower relative to the speed of light slow.

Fiber laser cutting machine is not a panacea, pls don't cut these materials with it

Fiber laser cutting machine is not a panacea, pls don't cut these materials with it
 

Many people believe that the fiber laser cutting machine belongs to the cutting machine category, and adopt imported laser, cutting range should be very wide, the effect should be much better than the other way, actually otherwise, cutting machine also are in special types, each cutting machine has his advantages and disadvantages.The following are analyzed in detail.

First, fiber laser cutting machine belongs to metal laser cutting machine processing category, so only for cutting metal, which cannot be cut fabrics, leather, stone etc. nonmetal, the reason is very simple, fiber laser cutting machine in the wavelength range not within the absorption range, or ceiling are not suitable, amounting to less than the desired effect of cutting, at present,
application in non metal cutting edge is not very obvious, of course does not preclude later with development needs in this regard.

Secondly, we don't recomend fiber laser cutting machine cut aluminum, copper and this type materials in long-term,because these materials belong to high reflective material (Note: high reflective sheet with the cutting surface smooth degree of concern is not big, mainly due to the wavelength of the laser not in these materials ideal absorption range, absorption effect is not good, most of the energy is reflected back, easy to damage protection lens in front of the laser head), the cutting effect is not good in long-term working . It will also increase the usage of consumables;

Finally,with the different power of fiber generotor,the cutting thickness is also different.The more power,the cutting thickness is more.And cutting thin metal,the speed is faster.Fiber laser cutting machine is very obvious for thin sheet cutting edge.

What auxiliary gas can be used laser cutting?

What auxiliary gas can be used laser cutting?

Laser cutting machine can use the auxiliary gas when cutting, mainly oxygen, nitrogen, air and argon, and the following we will introduce its use and characteristics for different auxiliary gases.

1.Atmosphere

Air can be supplied directly from the air compressor, so the price is very cheap compared with other gases. Although the air contains about 20% of the oxygen, but the cutting efficiency is far less than oxygen, cutting capacity and nitrogen. The cutting surface will appear micro film, but it can be used as a measure to prevent the film from falling off. Cut end face yellow.
The material is mainly applicable to aluminum, aluminum alloy, stainless steel, brass, galvanized steel, non metal and so on.

2.Nitrogen

Some times,when we cut some metal material,the cutting surface will form oxide film,adopt nitrogen can invoide the oxide film.The non oxidation cutting mask has the characteristics of direct welding, coating, corrosion resistance and so on. Cut face is white.
The main application of the plate are stainless steel, galvanized steel, brass, aluminum, aluminum alloy, etc.

3.Oxygen
