2.5D machine introduction

The Z axis on 2.5D laser machine is responsible for adjusting the focal length of the center circle point on the processing plane, as the engraving depth changes, the Z-axis will do fine-tuning of the following depth so as to achieve precision micro-machining fields such as relief and small-format micro-hole machining.

From technical part, we called it 2.5D laser machine, because its laser head still with a 2D laser head, but 2.5D laser machine has equipped with motorized lifting pillar. And the galvo head can be controlled by the software. Software can control laser head move when machine working, so it can achieve 3D relief. it means 3D laser, Z axis mirror inside laser head to move back and forth; 2.5D laser, Z axis stands for the third mirror to move automatically.

2.5D fiber laser machine can finish all 2D fiber laser work and can make 3D relief on flat metal surface. But 2.5D fiber laser machine can't make 3D relief on curved metal surface.  

This machine can do 3D relief on a variety of metals, such as stainless steel, carbon steel, various alloy steels, tool steels, hard alloys, aluminum alloys, chrome plating, nickel plating, zinc plating, various grinding, polishing metal surfaces, etc.

10, Manual gold and silver holder (optional)

①Plate holder can fixed material，In this way, it can be ensured that the material will not move during processing. And the machining accuracy is ensured.

②When you cut, if you put the metal plate directly on the workbench, you can't see whether the bottom has been penetrated by laser. It is impossible to determine whether it can be cut off.

③If you put it directly on the workbench, when the laser penetrates the material, it will be directly marked on the workbench.

The difference between 2D and 2.5D

1, 2D machines need to shake the column by hand, while 2.5D machines do not need to, there is a motor on the column, so 2.5D machine is easier to find the focus, reduce the error, it is also very easy to operate the machine, only need to measure the height from the bottom to the workpiece can find the focus, and then entered into the software so that we can also facilitate the operation.

2, 2D fiber laser machine use EZCAD2 as machine control board, While 2.5D fiber laser machine use EZCAD3.

3, The biggest difference between 2D and 2.5D is that 2.5D machines can do 3D reliefs while 2D cannot, 2D machine just

Precautions for machine maintenance

1, When the machine is not working, cut off the power supply of the machine.

2, When the machine is not working, cover the field lens to prevent dust from polluting the lens.

3, The circuit of the machine is in high voltage state during operation. Non professional personnel

4, should not repair it when starting it to avoid electric shock.

5, When the equipment is used for a long time, the dust in the air will be adsorbed on the lower

6, surface of the lens. Gently wipe the surface with a long fiber cotton swab or lens paper. Replace the cotton swab or lens paper every time.

7, During the operation of the marking machine, do not move the marking machine to avoid damaging the machine.

Now it seems that mopa lasers are becoming more and more popular, so do you really need a mopa laser? Do you really understand it? Today, let's take a look at the difference between a Q-switched laser source and a mopa laser source.

The main difference between them is that

A Q-switched laser source means that the pulse width is fixed and cannot be adjusted.

Mopa laser means adjustable pulse width.

However, the mopa laser wavelength is also 1064nm, which is also a fiber laser, which is just a series of fiber lasers. We can tell mopa laser or not from the laser source label and laser source model.

Raycus, JPT and IPG laser sources all have mopa laser sources. In the case of a mopa laser, you can easily find the letter "M" on the label or model number of the laser source. If your fiber laser has a mopa laser source, your software is also different from the others.

Mopa Machine Parameters Show is

Let's take 50W Raycus laser Source and 60w jpt Laser Source as examples to explain the difference 

1. From parameters:

50w JPT brand single pulse energy 1.25mj 

50W Raycus brand single pulse energy 1.0mj

60w single pulse energy 1.5mj 

It means 60w speed is faster than 50w for do the same work. 

50w Raycus frequency: 50-100khz, cannot adjust pulse width. 

50W JPT frequency: 1-600Khz, cannot adjust pulse width.

60w frequency: 1-4000khz, pulse width: 2-500ns 

Let's show you more clearly in this form.

2. From laser source type: 

50w is Q switched laser source; 60w is mopa series. Mopa advantages: 

2.1 marking colors on stainless steel <

2.2 engraving black color on Aluminum oxide, like iphone/Ipad housing engraving. 

2.3 engraving some plastic better than normal laser source. But plastic is complex, better to test before making a decision. Sometimes, UV laser is better for plastic.

3. From operation: 50w is easier because the adjustable parameters are less than 60w mopa. But we have all parameters, so needn't worry. 

4.Both brands are good. Raycus with the oldest history in China and is the best one in the past 8 years. JPT at the start is famous for their mopa series then developed very well in recent years. 

And JPT brand is quieter when working, 

So JPT price is a little expensive than Raycus brand. 

For cutting, 50w and 60w speed won't have a big difference. If you have the budget, for sure 60w is a good choice. Otherwise, 50w is not bad.

MOPA laser source is wide range of application,There are different types of laser machines, each designed to achieve specific tasks on specific surfaces. In this blog, we are going to discuss MOPA lasers and what are the applications that can be achieved with a MOPA fiber laser.

At first, we need to know what’s the MOPA laser.Master Oscillator Power Amplifier, commonly called MOPA, is one of the most recent innovations in fiber laser technology, also it’s the most famous series laser source in JPT brand.MOPA laser source can use to process metal and some non-mental.

WHAT CAN I ENGRAVE WITH A MOPA LASER MACHINE?

Due to this larger range in pulse duration, the scope of applications is larger for a MOPA laser. A MOPA laser can produce precise, high contrast engravings on the following materials:

l Aluminum

l PC plastic

l PLA plastic

l PBT plastic

l ABS plastic

l Carbon steel

l Silicon plastic

l Stainless Steel

l Gold

l Brass

l Silver

l Nickel

l Metals

l Copper

l Carbide

l Titanium

l Platinum

l Tungsten

l Nylon plastic

What’s the advantage for MOPA laser machine?

1. Good for metal

When cut metal done, the metal will react with their environment and get rust, but MOPA laser have high single power, and it will have lower heat on material, so it can keep material have less change due to the heat and environment.

2. Marking color on Stainless steel

MOPA laser source can mark color on stainless steel, for some logo, picture engrave.

But it will need long time for a complete color engrave, you need to find a good parameter setting for every color, then engrave the whole file.

3.Engrave non-metal, such as keyboards mark, animal tags mark,ID cards engrave, logo mark, nylon engrave white.

3. Black mark on alumina.

For the alumina engrave, regular fiber laser to engrave will only remove the surface and get its original silver color and not clear. If use the MOPA fiber laser, it’s short pulse duration will not remove the surface layer and just get simply paint by laser, so that, this way will get a great black color on alumina.

The MOPA laser source lifetime is longer than regular laser source, also it with low maintenance cost and high usage experience, if you want to do more works by one machine, i suggest choose a machine with JPT laser source,It gives you a much better experience on laser machine.

laser relief is a kind of sculpture based on the surface of material,which uses laser beam as tool to cut or burn the material to form convex 3D graphics and texts.

In the 3D laser relief processing, there are some basic knowledge we need to know. Here I will introduce some knowledge from the3D dynamic focusing system, galva laser head to laser applications.

first, we need to know what files we can use to do 3D relief.

3D model need STL files, only this files we can do 3D relief and engrave of 3D concave convex relief.

second,process characteristics

3D dynamic system fiber laser machine has a wide range of applications. There are tree mainly characteristics for 3D laser engrave machine: widely applications, high efficiency and high precision.

Here I will introduce them one by one.

1. Widely applications

Almost metal we can use to do 3D relief. Such as brass,copper,silver, gold, die steel, stainless steel.The laser spot is thinner than the knife and the processing effect is finer.

Therefore, laser relief processing is widely applications in handicrafts industry,special industry, mold industry and so on.

3D relief on metal.

2. High efficiency

3D dynamic axis and XY axis fully coordinated by software, and layered focus compensation is completed in microseconds with high efficiency. In the proper configuration, it’s efficiency can reach or exceed CNC machine. And we can get a very fantastic effect then CNC machine.

3. High precision

With the increase of processing layers, the dynamic axis of 3D dynamic focusing system cooperation to adjust the focal length and adjust the spot in real time , which can ensure that the focus spot is controllable by software in the whole processing , and can obtain higher accuracy than the traditional laser scan head.

3D relief 50times magnification effect display.

Third, how to make the effect of relief to be best.

Before laser relief engrave, the most appropriate parameters need to be tested, such as marking parameters, filling line distance,layer thickness and so on.

1. When debugging the marking fill parameters，it is necessary to make a uniform frosted shading.

Filling parameters debugging effect as references

2. Layers parameters :Use the adjusted filling parameters to engrave 50~100 times on the material.Total depth/engraving times=the depth of a single process, that is the layered thickness of relief sample.

3. Laser on delay:when we need to do the sample what we want to test, we need to get the relief surface to be smooth, for example:

4. Clean: dust is generated in the process of relief engraving, which needs to be cleaned every 3-5 layers of engraving, otherwise too much dust will cause the relief not to form.

Finally,suggestions on laser power selection based on marking speed and effect:

Different power to engrave effect as references.

In a word, 3D machine world is big, we can go to explore and discover more applications, also test more great parameters by ourselves.

How to use fiber laser machine?

The use of fiber laser marking machine is actually very simple. When sending the machine, we will also attach a detailed instruction manual and a video tutorial. Customers do not need to worry about how to use the machine.

Next, I will explain to you how to use the fiber laser marking machine.

1.First start the laser marking machine system, then turn on the computer that controls the machine, and then click the ezcad2 laser marking machine software that has been installed on the computer desktop.

2. After entering the laser marking machine software, we can see that there is a toolbar on the left. This side can draw graphics or import bitmap and vector files. We can change the parameters on the right according to the required functions.

3.Draw text, click the "FI" icon on the left toolbar, and then click the work area. At this time, a default text "TEXT" will appear. Change the text we need in the text box on the left and click Apply to take effect. We can also Change the size of the text, change it to the size we need, click Apply to take effect.

4.Import a bitmap, a bitmap is what we often call a picture composed of pixels, which is our ordinary picture, click the bitmap import icon, and select the picture we need to import on the computer. Then click to fix the dpi value of the laser marking machine, we generally change it to 500. All select grayscale dots, and then check the dot mode, we generally set it to 0.3.

5.Power adjustment, on the right side of the software, uncheck it, we can change the desired parameters, if we want to mark faster, we can increase the speed, and if we want to engrave deeper, we can increase the power. Using different materials with different power and speed can achieve the effect we want. In general, the default parameters can be used.

6.Filling function, the filling function has an H mark at the top of the software, we first select the text we need to fill in the blank, and then click the H mark filling function, and change the Line distance  to between 0.1~0.3 or 0.5. Then click OK. Whether the marking effect is good or not, this filling function is very important. By default, our text is hollow, so we need to use the filling function.

7.Import vector files. Vector files are generally generated by some vector software, including CAD files, which can be directly imported into the laser marking machine software. The operation steps are similar to those of importing bitmaps. Vector files are similar to ordinary bitmap files. The difference between image files is that the speed of printing vector files is very fast because vector files are composed of lines, and bitmaps are composed of pixels. Under the principle of laser marking machine, the speed of printing vector files is generally the speed of bitmap printing. more than 5 times, the effect will not be distorted, so we generally recommend that you use vector files for marking.

The above introduces how to use the fiber laser marking machine. These are some basic operations.
