Important parameters of laser cutting machine metal sheet

The auxiliary gas pressure, laser power, cutting speed, focus position and other parameters have a great influence on the cutting effect of the laser Cutting Machine metal sheet.

Auxiliary gas pressureThe role of the auxiliary gas is to blow away the slag, cooling material and combustion-supporting when the cnc laser fiber cutting machine is running. Oxygen, compressed air, nitrogen and inert gases are more common auxiliary gases.Oxygen can participate in metal combustion, which can improve cutting efficiency and is suitable for cutting most metals; inert gas and air are suitable for cutting some metal materials (such as aluminum alloy) and non-metal materials, and can prevent materials from burning.If the auxiliary gas pressure is too high, a vortex will appear on the surface of the material, which will weaken the ability to remove the molten material, resulting in wider slits and rough cutting surfaces; if the pressure is too low, the molten material cannot be completely blown away, and the lower surface of the material will stick.

With dregs. Therefore, in order to obtain the best cutting quality, the auxiliary gas pressure should be adjusted when the steel sheet cutting machine laser is running. Laser powerLaser power will affect many aspects of fiber laser machine table cutting, such as cutting speed, slit width, cutting thickness and cutting quality.

PTJ has more than decades of experience in China and can offer one-stop 3d Printing service (3d printing parts & CNC machining prototype) for our OEM customers.

The power depends on the material characteristics. For example, materials with high melting points (such as alloys) and high reflectivity of the cut surface (such as copper and aluminum) require larger laser power.The laser cutting machine sheet metal has a laser power to obtain the best cutting quality during processing. When the laser power is lower than this laser power, imperviousness or slagging will occur; when it is higher than this power, it will burn excessively.

Cutting speedWhen the fiber metal laser cutting fiber machine is running at the ideal cutting speed, the section of the material to be cut is smooth and will not produce burrs, and the cutting surface will show a relatively stable line. When the auxiliary gas pressure and laser power are constant, the cutting speed and the slit width show a non-linear inverse relationship.

When the cutting speed is relatively slow, the action time of the laser energy on the slit is prolonged, resulting in cutting If the slit width increases, or the slit underneath is too wide, the cutting quality and production efficiency will be greatly reduced.To speed up the cutting speed, the action time of the laser beam energy on the workpiece becomes shorter, so that the heat diffusion and heat conduction effects become smaller, and the width of the slit is correspondingly reduced. However, when the speed is too fast, the workpiece material to be cut will be impenetrable due to insufficient cutting heat input. Focus positionThe distance from the laser focus to the surface of the workpiece is the focus position.

The roughness of the cut surface, the slope and width of the slit and the adhesion of the molten residue are directly affected by the focus position. When the focus position is too far forward, the heat absorbed by the lower end of the cut workpiece will increase, which will cause the cut material and the melted material near the slit to flow on the lower surface in a liquid state. After cooling, the melted material will be spherically stained. Attached to the lower surface of the workpiece; if the focus position is behind, the heat absorbed by the lower end surface of the material being cut is reduced, so that the material in the slit cannot be completely melted, and some sharp and short pieces will adhere to the lower surface of the plate Residue.

Normally, the focus position should be on the surface of the workpiece or slightly lower, but different material requirements are different. When the cnc fiber laser cutting machine metal cuts carbon steel, the cutting quality is better when the focus is on the surface of the plate; while the metal cutting laser machine is for stainless steel When cutting, the focus should be about 1/2 of the thickness of the sheet for better results.

Laser cutting of flexible OLED screens opens the era of smart phone “folding”

In recent years, one of the hottest topics in the mobile phone industry is the foldable phone. The foldable mobile phone, which integrates tablet computers and mobile phones, sounded the horn of new technology. Originally envisioned as a smart device that opened as a tablet and folded as a mobile phone, it is now no longer a fantasy, but a real product. Rouyu Technology, Samsung, and Huawei have launched their own foldable phones.

( MATE X Huawei folding screen phone)

 

The screen of a foldable mobile phone uses a flexible OLED screen. The so-called flexible screen refers to a screen that can be bent and folded freely. As a brand-new field, flexible screen faces many problems in the processing process, and puts forward higher requirements on the processing technology. Compared with the traditional processing of brittle materials, OLED Display screens must be processed with the highest precision in the manufacturing process due to its complex layering mechanism to ensure quality and yield.

 

The laser is the absolute king of high-precision processing. The processing of flexible screens is inseparable from the laser cutting process. The traditional mechanical processing method is used to cut the flexible screen, which is prone to problems such as edge collapse and cracks. In contrast, the laser cutting process uses a non-contact processing method that does not generate any mechanical stress and has no effect on the mechanical characteristics of the material itself. After drawing on the computer, the laser Cutting Machine can realize the special-shaped cutting of the flexible OLED Panel according to the design drawings, which has the advantages of automatic cutting, small cutting edge collapse, high precision, diversified cutting, non-deformation of cutting, fine processing, high processing efficiency, etc. Etc.

Tube laser cutting machine cutting pipe

Metal pipes are often used in aerospace, construction machinery, automobile industry, petrochemical, agricultural and animal husbandry machinery and other industries. It is necessary to process metal pipes into parts of different shapes and sizes to meet the requirements of different working scenarios. The tube laser Cutting Machine is particularly suitable for processing various metal pipes. High flexibility and high automation are the characteristics of the tube laser cutting system, which can realize the production mode of different materials in small batches and multiple varieties.The following will introduce the key technology tube laser cutting system.

Light guide focusing system The function of the light guide focusing system is to guide the light beam output by the generator to the cutting head of the focusing light path. For laser cutting pipes, the focused spot diameter of the focused beam is small and the power is high to obtain high-quality slits. This requires the generator of the to output low-order modes. When the laser cutting machine tube cuts the tube, in order to make the beam focus diameter smaller, the order of the transverse mode of the laser should be small, preferably the fundamental mode.

The cutting head of the pipe fiber laser cutting machine is equipped with a focusing lens. After the laser beam is focused by the lens, a smaller focusing spot can be obtained, so that high-quality pipe cutting can be carried out. To Trajectory control of cutting headWhen the fiber laser tube cutting machine cuts the pipe, the shape of the pipe is relatively complicated and belongs to the space surface.

PTJ has more than decades of experience in China and can offer one-stop 3d Printing service (3d printing parts & CNC machining prototype) for our OEM customers.

It will be difficult to program and process with conventional methods. This requires the operator to select the correct processing path and appropriate reference points according to the processing requirements. The numerical control system records the feed situation of each axis and the coordinate value of the reference point, and then uses the spatial straight line and arc interpolation function of the fiber laser cutting machine for steel tube system to record the coordinate value of the processing process and generate the processing program. Automatic control of focus position

An important factor affecting cutting quality is the focal position. It is one of the key technologies for laser cutting pipes to make the vertical direction of the focal point relative to the surface of the workpiece unchanged through automatic measurement and control devices. Through the integration of the laser focus position control and the laser processing system linear axis (XYZ), the movement of the cutting head is lighter and more flexible, and the position of the focus point can be fully understood, avoiding the cutting head and cutting pipe or tube during processing. Other objects collide.

Introduction of metal stamping parts processing knowledge

The processing of metal stamping parts is the production technology of using the power of conventional or special stamping equipment to directly subject the sheet metal to the deformation force and deform in the mold, so as to obtain product parts with a certain shape, size and performance. Sheet materials, molds and equipment are the three elements of stamping processing. Stamping is a method of metal cold deformation processing. Therefore, it is called cold stamping or sheet metal stamping, or stamping for short. It is one of the main methods of metal plastic processing (or pressure processing), and it also belongs to material forming engineering technology.

Because of the superiority of stamping, stamping has a wide range of applications in various fields of the national economy. For example, in aerospace, aviation, military industry, machinery, agricultural machinery, electronics, information, railways, post and telecommunications, transportation, chemicals, medical appliances, household appliances and light industry, there are stamping processes. Not only is it used in the entire industry, but everyone has direct contact with stamping products. There are many large, medium and small stamping parts on airplanes, trains, automobiles, and tractors.

Precautions for bright surface cutting by fiber laser cutting machine

Fiber laser Cutting Machine is widely used in industrial production, sometimes we will find that some metal cutting surface is very smooth, such as a mirror, in fact, in the laser cutting process technology, the cutting surface of carbon steel can be cut very smooth, like a mirror-like effect, commonly known as “bright surface cutting”. Bright surface cutting is mainly used for medium thickness carbon steel, the steel plate is too thin or too thick can not achieve bright surface cutting. So what should we pay attention to when we carry out bright cutting? Here follow GOLD MARK to understand.1, to control the cutting speed. Too fast a cutting speed will lead to incomplete material burning, the workpiece can not be cut through, while too slow a speed will lead to excessive burning, so that the workpiece melting deformation. Under the premise of ensuring that the workpiece will be, the cutting speed should be increased as much as possible.2, adjust the nozzle height. Nozzle height will affect the beam quality, oxygen purity and gas flow, when the lower the nozzle, the better the beam quality, the higher the oxygen purity, the smaller the gas flow, so the bright surface cutting should try to adjust the height of the lower.3, adjust the cutting air pressure. In the oxygen cutting of carbon steel, the combustion of the material will give off a lot of heat, so the oxygen air pressure should not be too large. Generally speaking, the lower the air pressure in the cuttable range, the brighter the cut section, but in order to ensure cutting stability, usually increase a certain percentage on the basis of the cut-off air pressure.4, adjust the cutting power. For different thickness of the plate, the greater the thickness, the higher the power required.5, adjust the size of the cutting focus. Fiber laser by the nozzle ejected beam is a certain diameter, in bright surface cutting, usually use the nozzle is smaller. If the focal point is too large, it will lead to nozzle hot, affecting the quality and stability of cutting, and in serious cases can even directly lead to nozzle damage. Therefore need to find out the size of the nozzle can withstand the focus value, and then adjust.6, choose the size of the nozzle. Half of the nozzle is smaller, the brighter the cut section, the better the effect.Guangdong China cut CNC Machinery Co., Ltd. is a high-tech industry enterprise specialized in researching, manufacturing and selling the machines as follows: Laser Engraver, Fiber Laser Marking Machine, CNC Router.
