The advantage of XT W-series

First,

1.For the machine body:

For the machine body, the advantage of XT W-series, it use the new design plate welding machine body, dust remove will better than the before machine. And the machine body and control box separately.

Second
2. Add the roller loading device:
This is the new function for the machine. It will help customers to upload the plate easier into the machine. Special for the open type machine. When you load the plate, the 4 rollers will up and then you can with the help of roller to remove the plate into the machine body.

Third

3.Laser source put into the control box:

For the new design machine, we put the fiber laser source into the control box. It will better than put the laser source into the machine body. Why?

When you operate the machine, even the machine body is strong like XT LASER machine body, long time use will let the machine body a little shake, when the laser source put into the machine body, long time use will broke the laser source line. That is why we redesign to put the laser source into the control box.

The other thing is that in the hot weather place, like United Arab Emirates, the temperature is very hot. If your factory do not have air conditioner and the temperature is high. Most of our customers will add one air conditioner for the laser source and electric parts cooling.

When the laser source in the control box, then only need to add one air conditioner can make all parts cooling.

For the details like the air pipe and the electric pipe will have some update, it will help you to easy to check it.

One more thing, for the fiber laser cutting machine now we give you 3 years warranty for whole machine (Except easy wear parts and human factors)

How to maintain the water chiller in cold weather-Wendy

/in , /by

How to maintain the water chiller in cold weather

This passage we will talk about the details for water chiller maintainance in the winter.

When entering the winter, the water chiller pipe may be breezed because the ambient temperature is too low.

Then resulting in significant damage to the relevant core components.

Because the density of ice is less than the density of water, it will borke the water chiller and the inside of the cooled equipment.

Due to volume expansion, resulting in significant damage to the relevant core components.

We remind you to do the relevant prevention work.

Please refer to the following for details.

For air-cooled chillers, because of the water-cooling heat dissipation, there is no water cooling system for the water-cooling fiber laser cutter machine.

The air-cooling machine only needs the anti-freeze for the heat-dissipating part of the air-cooling unit.

So we should pay more attention to the lubricating oil of the fan if it is continuously running.

There is no need to worry about the antifreeze of the lubricating oil.

If  u use the chiller intermittently or not use for a long time, you should pay attention to antifreeze.

If u do not use it for a long time, u should clean the air-cooled fiber laser cutter and coate with protective oil.

Peole should keep waterproof to prevent frostbite in the air-cooled machine because of cold weather in winter.

If we use it intermittently, we should scrap off the fan oil when the production is stopped.

And then applying an appropriate amount of lubricant when using.

In the case of normal operation of the air-cooled chiller, we must assure the sufficient water flow and water pressure.

And then we could avoid the problem tof frozen cooling water.

Unlike the air-cooled chillers, the cooling and cooling components of water-cooled chillers are water circulation systems rather than fan systems.

So the antifreeze task is more difficult, even during normal operation.

Tips for avoiding freeze of water chiller on fiber laser cutter

1. The recommended method for preventing icing is to keep the water chiller. And the equipment at a temperature above 0 °C.

2. If the temperature does not reach above 0 °C, keep the cooled equipment and the water chiller turn on.

If the water in the pipe is always flowing, it can prevent icing.

Of course, in this case, if the water chiller is shut down for a long time due to a malfunction or a power outage. There is also a certain risk of icing.

3. During the Spring Festival and other holidays, if the above two points are not available, jepp the water in the water cooler tank, piping and internal water parts drain as much as possible.

4. If the above methods are not possible. For the water chiller, you can add the antifreeze  3:7 (3 is antifreeze, 7 is water).

After adding antifreeze, it can resist -20 °C without freezing.

Why there are many different price level in the marketing-Wendy

Why there are many price level machine?

Why there are many different price level machine?

Why there are many price level machine?

Accurately speaking, each fiber laser cutting machine has the same effect, but has different prices, different service life, different operating efficiency, different component parts and so on. The quality of the core components of the laser cutting machine directly affects the performance of the entire equipment.

1. Fiber laser

The fiber laser is the „heart“ of the laser cutting machine, and it is the „power source“ for the action of cutting. The fiber lasers with the highest configuration on the market are: German IPG lasers, British SPI lasers. Some people will say that domestic lasers have developed rapidly over the years and the technology is very sophisticated. But it turns out that there are still many insurmountable gaps between domestic and imported lasers in many aspects.

The laser can directly affect the cutting efficiency, cutting quality, service life and so on. Therefore, the laser has become one of the primary factors in the purchase of equipment.

2, stepper motor

The stepper motor directly affects the cutting accuracy of the device. Generally speaking, the feeding motor and the laser are relatively more mature and more reliable. It is not easy to choose an unknown brand.

3, cutting head

The laser cutting head is the closest position to the cutting workpiece and is the laser output device. It consists of a nozzle, a focusing lens and a focus tracking system. The quality of the cutting head also affects the focus of the laser beam, which affects the quality of the cut.

4, servo motor

The servo motor is equivalent to the engine of the laser cutting machine. It can make the control speed and position accuracy very accurate. Therefore, the high-quality servo motor can effectively ensure the cutting precision, positioning speed and positioning accuracy of the equipment.

Of course, there are many components of the laser cutting machine, and each component is indispensable. The core component is especially important. When purchasing equipment, please also consider it.

Factors affecting the cutting quality of fiber laser cutting machine-June

Factors affecting the cutting quality of fiber laser cutting machine

Factors affecting the cutting quality of fiber laser cutting machine

At present, many companies are using metal fiber laser cutting machines. So, what factors affect the quality of cutting during actual use? Xintian Laser introduces you to everyone:

First, the laser output power and mode

The higher the output power of the laser, the better the quality of the cut on the same thickness of the board. The higher the fit of the laser cutting mode to the material, the better the quality of the cut.

Second, the material of the processed parts

The effect of fiber laser cutting machine on different materials is different. Different metal materials have different characteristics. The absorption of laser heat is also different. Common stainless steel, carbon steel and iron plates absorb heat quickly. The quality of the cut is also high, and the opposite highly reflective material (aluminum, copper) is more difficult to cut.

At the same time, the thickness of the workpiece and the smoothness of the surface also affect the quality of the cut.

The metal fiber laser cutting machine is suitable for cutting thin plates. The carbon steel under 12mm and the stainless steel below 6mm have obvious cutting effect, the best quality and the efficiency can be guarante. In addition, in general, the flatter the surface of the material, the better the quality of the cut.

Third, the choice of focus position

It is very important that the fiber laser cutting machine determines the corresponding position of the focus and the material surface before working, which is directly related to the quality of the cutting. The power at the focus is the highest, and most of the time the focus is at the surface of the cut material. When the focus is at the best position, the minimum cut, the highest efficiency, and the best cutting speed for optimal cutting. result.

Fourth, the processing speed of cutting

The influence of cutting speed on the quality is very direct. The speed of the fiber laser cutting machine is too fast. Which is easy to cause the material through. And the speed is too slow to cause the residual slag and the phenomenon of burning edge. Therefore, we need to adjust the parameters according to the actual thickness calculation of the workpiece to try to cut to achieve the best cutting speed.

Finally,Auxiliary gas pressure and type

The pressure of the auxiliary gas also has a certain influence on the cutting quality. When a laser cutting machine use to cut some metal sheets at high speed. A higher gas pressure is generally require to prevent the back side of the slit from being slag. If the thickness of the material increases or the speed of the cut decreases. Then the gas pressure of the assist gas should be lower. And in order to prevent oxidation of the cut edge, the appropriate gas pressure should also be adjusted.

Application of three laser processes in the automotive industry—Winnie

/in , , /by

Application of three laser processes in the automotive industry

Since the early 1980s, the automotive industry has been one of the main drivers of the high-power laser industry. Because it has strict requirements on the quality and reliability of laser sources. Compared to traditional manufacturing techniques, laser technology can bring greater benefits in the areas of cutting, welding and marking. Because laser technology is more flexible and easy to automate than traditional technology. It can meet the core requirements of the entire industry.

At the beginning, the laser is only use for simple cylindrical part welding. Such as the automatic transmission components of automotive. Nowadays, Lasers are commonly use in processes that process vehicle structures. For example, Roof welding, door welding, three-dimensional cutting of hydro formed parts, door spring annealing, instrument panel welding, marking, etc. With the development of lightweight vehicles, new materials, new structures and new processes are constantly emerging, and the safety performance of automobiles is continuously improve. So what are the applications of laser technology in automobiles?

1.Laser welding

The adoption of laser technology welding for its advantages of high welding speed, stable welding quality, high welding precision, small thermal deformation of materials. Besides that it is easy to integrate into the automation operating system, which is an advance welding method that is widely use in modern industrial production and has excellent reputation. Laser welding has  widely use in automobiles, such as welding of automobile bodies, pipe welding, welding of automobile batteries, and plastic welding of instrument panels. Lasers have unique advantages in terms of welding strength and welding precision and speed.

2. Laser cutting

Laser cutting is also one of the most frequently laser applications. Fiber lasers and CO2 lasers can combine with standardized 2D and 3D cutting systems to cut carbon steel. Stainless steel, aluminum and other metals.  When processing different parts of a car. Car manufacturers take advantage of the advantages of laser cutting. Such as high cutting edge quality, low heat input, and fast processing speed. Automotive parts and materials, including a variety of metals, which can cut by the laser such as airbag fabrics and composite materials use in automotive interiors. As a flexible processing tool, the laser can easily integrated into robots and other automation devices and provides solutions for cutting various automation components and materials.

3. Laser surface treatment

In addition to traditional processes such as laser cutting and laser welding. Lasers can also use in a variety of surface treatment applications such as laser hardening, laser de-layering, surface activation. And laser surfacing. In the laser surfacing process, the most well-known is laser cladding.

The basic materials such as metal wire or powder can be melted by laser radiation to achieve metallurgical bonding.  The dilution rate of the metal of the parent component is less than 5%. . The automotive processing industry usually uses powder for laser surfacing. Which can be used as a protective film for workpieces to prevent wear and corrosion, as well as high temperature and corrosion resistance (liquid).  In the automotive industry, the minimum distortion rate and high flexibility of the workpiece are two important criteria.  Thermal micro cracking and porosity are also avoided due to reduced heat input and the use of additive materials.  Laser surfacing with filler wire can be used to repair workpieces, improve material wear resistance, achieve small design improvements, and correct manufacturing defects.

Can a laser cutting machine cut a galvanized sheet?+Karina

/in /by

Can a laser cutting machine cut a galvanized sheet?

Can a laser cutting machine cut a galvanized sheet? Machining metal has become the main means of modern processing enterprises. Laser cutting uses a focused high-power-density laser beam to illuminate the workpiece, causing the irradiated material to rapidly melt, vaporize, ablate or reach a flash point while simultaneously passing a high-speed airflow coaxial with the beam. The molten material is blown off to cut the workpiece.

Galvanized sheet is a relatively common material using in the manufacturing industry. The galvanized steel sheet using to prevent the surface of the steel sheet from corrode and prolong, and the surface of the steel sheet coating with a layer of metal zinc. Mainly used in home appliance casings, civilian chimneys, kitchen appliances, etc., is this material suitable for laser cutting machines?

Generally for galvanized sheets, laser cutting machines can cut easily. Can using most organic and inorganic materials. Various metal materials commonly using in industrial manufacturing systems, regardless of their hardness. Copper, aluminum and alloy sheets are fine.

Cutting galvanized sheet

In the process of processing galvanized sheet, auxiliary gas needs to add. The purity and pressure of the auxiliary gas directly affect the quality of the cut sheet. The purity of oxygen used for cutting should be above 99.6%. When the purity of cutting oxygen higher, the section of cut galvanize sheet more quality . The roughness and quality higher, and of course the cutting cost increase. The purity of nitrogen should be above 99.5% when cutting. Increasing the purity of nitrogen ensures that the slit does not change color during the process of cutting the galvanized sheet.

The cutting thickness of high power laser cutting machine

 

The cutting thickness of high power laser cutting machine.
At present, with the continuous development of laser cutting technology. The cutting ability of high-power laser cutting machine greatly improved. Taking our commonly used stainless steel and carbon steel as an example.  The high-power laser cutting machine can process up to 36mm in the most extreme cutting state; the stainless steel can reach 25mm.
However, in order to ensure the processing efficiency, the general cutting thickness is  less than 25mm for carbon steel and less than 16mm for stainless steel to achieve the best cutting speed and precision.

 

At present, the maximum cutting capacity of high-power laser cutting machine in the industry:

Firstly, Carbon steel is 36mm (the quality of the steel plate is good. The speed can be about 650mm/min). If the material of 36mm steel plate is good, the machine is good. The cutting quality is still very good. The stainless steel is 25mm , but the domestic users generally aim for laser cutting, low carbon steel 25mm or less, stainless steel 16mm or less.

However, for carbon steel sheets up to 10 mm, high power laser cutting machines of 1000 W. This is because the laser cutting has a narrow cutting width, generally between 0.1 and 0.5 mm; the cutting precision is very high, less than 0.05 mm. And the hole center error is between 0.1 and 0.4 mm, and the contour size error is also 0.1 to Between 0.5mm. The cutting section is smooth, the roughness of the incision is less than 25μm.

Generally speaking, it  use a high-power laser cutting machine for cutting metal materials. Such as carbon steel sheets within 12 mm or stainless steel sheets within 10 mm. High-power laser cutting machine has no cutting force, no distortion in processing. Whether it is simple or complex parts, laser can be used for precision precision rapid cutting: its slit is narrow. Cutting quality is good, automation degree High, easy to operate, low labor intensity.No pollution: automatic cutting and nesting can be realized, material utilization rate is improved, production cost is low, and economic benefits are good.
