Six steps of selecting and buying a fiber laser cutting machine

Six steps of selecting and buying a fiber laser cutting machine

In recent years, laser cutting technology has been more and more widely applied in sheet metal, handicrafts and other processing industries. Fiber laser cutting machine technology has been quite mature, cutting industry has a very large market share. But there are still a lot of users about how to choose a suitable fiber laser cutting machine, and there are all kinds of problems. Here I will introduce how to choose a fiber laser cutting machine correctly, which can be considered from the following aspects.

1. the requirements for the materials and business processed by the enterprise

First of all, we should consider the scope of our business, the thickness of the cutting material, which material needs to be cut, and then determine the size of the equipment that needs to be purchased and the size of the worktable. At present, the power of the laser cutting machine on the market is between 500W-6000W, and the size of the manufacturers of the worktable can be according to the customer. Demand to customize.

2. The initial choice of the manufacturer

After we confirm the demand, we can go to the market to understand or to see the performance and basic parameters of the machine. Select a number of strong and price preferential manufacturers for early communication and sample, and later we can carry out field inspection, the price of the machine, machine training, payment methods, after-sales service and so on more detailed discussion.

3. The size of laser power

When we choose the performance of laser cutting machine, we should give full consideration to our environment. The size of the laser power is very important, for example, we often cut the metal sheet below 6mm, then we choose 500W-700W laser cutting machine to meet the demand of production. If we cut more than 6mm material, we need to consider a larger power machine, which is very helpful to the cost control of enterprises.

4. The core part of the laser cutting machine

We also need to pay great attention when choosing some important parts of laser cutting machines. In particular, the laser generator, laser cutting head, servo motor, guide rail, water tank, etc., we have to distinguish whether it is made in China or imported. All these components directly affect the cutting speed and accuracy of laser cutting machine.

5. Equipment quality and use stability are also important indicators.

Now the research and development cycle of the product is short, the renewal and replacement are getting faster and faster. The variety of products, the sample trial production and the mass production are more. How to guarantee the customer order, maintain the reputation of the enterprise, and enhance the competitiveness of the enterprise is also the arduous task for each operator. Therefore, the selection and purchase of stable processing equipment is the premise and basis, as far as possible to choose the brand with high market share, perfect after-sales service system, many after-sales service outlets and long market inspection. We can not covet cheap products and buy poor quality products without after-sales service, which will have a huge impact on the production of enterprises.

6. After-sale service

The after-sales service of each manufacturer varies greatly, and the warranty time is uneven. In after-sales service, we should not only provide customers with effective daily maintenance programs, but also have a professional training system to help customers get started as soon as possible.

No matter how good a laser cutting machine is doing, the user will encounter a variety of problems in the process of using it. When it meets the problem that the customer can’t solve, it is very important for the manufacturer to provide a timely solution. It is also an important consideration when we choose to choose the laser cutting machine. Factor。

5 Common Errors in Laser Engraving and How to Avoid Them

5 Common Errors in Laser Engraving and How to Avoid Them

Whether you are an accomplished engineer or a novice maker, learning the proper uses of design equipment to avoid pitfalls and mistakes takes time and experience.From time to time, issues come up that leave designers wondering what they did wrong or how they could do something better. This is true in any field and laser engraving is no different.Knowing how to avoid these errors so they don’t come up again is half the battle. With that in mind, let’s talk about five of the most common mistakes when it comes to laser engraving and ways to avoid them in future projects.


 

Error 1: Engraving Fabric but the Laser Burns through the Material

The first step in avoiding burning fabric with a laser engraving/cutting machine is to understand which fabrics can withstand the process and at what temperatures. Heartier fabrics such as denim, canvas and leather can withstand higher power settings during engraving. But when it comes to delicate fabrics, it is important to start your settings at high speed (near or at 100%) and low power (around 5% to 10%). Test these initial settings on some spare material, and if the fabric can withstand it, increase the power until you get the results you are looking for.

When it comes to direct-to-garment engraving, it is helpful to lower the dots per inch (DPI) at which you engrave. The higher the DPI, the more material will be removed. Engraving at a lower DPI helps ensure the laser just slightly vaporizes the top layer and doesn’t burn entirely through the fabric. Most fabric engravings do fine at 150 to 300 DPI.

Error 2: Acrylic Doesn’t Produce a Frosty White Engraving

More than likely, this is caused by using the wrong acrylic in the application. Two types of acrylics are typically used in laser engraving and both are suitable for different applications.

Cast acrylic sheets and objects are made from a liquid acrylic that is poured into molds that can then be set into various shapes and sizes. This type of acrylic is ideal for engraving because it turns a frosty white color when engraved, making it suitable for awards and plaques. It can be cut with a laser, but it won’t give projects flame-polished edges.

The other type of acrylic used in laser engraving is called extruded acrylic, which is formed into sheets by a machine. Extruded acrylic is generally less expensive than cast acrylic because it is formed through a higher-volume manufacturing technique. However, it does react very differently with the laser engraving machine. This type of acrylic cuts cleanly and smoothly and produces a flame-polished edge; however, when engraved, it doesn’t produce that frosted look, but rather a clear engraving. So make sure you are using cast acrylic if you want a frosted white finish.

Error3: Inconsistent Glass Engraving

Oftentimes, when a laser strikes glass it will fracture the surface but not engrave deeply or remove the material needed to engrave fully. The fractured glass surface will produce a frosted appearance, but can be rough and chipped depending on the type of glass that is being engraved. While the frosted look is desired, no one wants a rough surface or chipping.

In order to produce a smooth frosted finish, try incorporating one or several of the tips below:

  • Use a lower resolution, about 300 DPI, which will produce a better result on glass as you separate the dots you are engraving.
  • Change the black in your graphic to 80 percent black.
  • Run your laser engraver with Jarvis Dithering (this dithering pattern can be found in Epilog’s print driver), which will help to provide a smooth finish.
  • Sometimes, applying a thin, wet sheet of newspaper or a paper towel to the engraving area will help with heat dissipation and improve the engraving process. Just make sure there are no wrinkles in the paper after it is applied.
  • Another way to dissipate heat is to apply a thin coat of liquid dish soap to the area you’re engraving – either with your finger or a paper towel.
  • Finally, if there are shards of glass after engraving, polish the area with a non-scratch scour pad.

Error4: Wood Engraving Produces Different Results on the Same Setting

Wood is one of the most laser-friendly materials available not only because it can be cut very easily, but also because it engraves very well.

However, different woods have different reactions when they are laser engraved and produce different results. Lighter woods, like cherry or maple, produce a nice contrast where the laser burns away the wood, while denser woods require more laser power to cut or engrave.

Grain density can change dramatically depending on the type of wood you are working with. Cherry, alder, walnut and maple have fairly small veins of grain in them, while oak has medium to large veins. For example, if a large square was engraved into a piece of cherry, it would have a very uniform appearance; the area engraved would be smooth with little variation in height. However, if the same square was engraved into a piece of oak, its appearance would vary greatly in height and would have a very non-uniform appearance.

Here are some tips when engraving with wood:

  • Maple and alder are some of the the most popular woods for engraving, providing a rich contrast.
  • Bare wood engraving produces smoke and debris during the process that can become embedded into the grain of the wood. To reduce this effect, always engrave from the bottom up – this helps draw any smoke away from the engraving.
  • When engraving stained wood, excess smoke and debris can be wiped off the surface of the wood with a damp cloth after engraving.

Error5: Laser Engraver Doesn’t Perform as Fast Anymore

Clean your machine! Much like other types of design equipment, a clean machine produces better results than one that is not properly maintained. Maintenance requirements are included in your laser machine user manual. If a drop in performance happens quickly, checking and cleaning the optics may be the first step in correcting the problem.

We recommend inspecting the optics in the laser (the lenses and mirrors) weekly and cleaning as needed. If you’re cutting materials that produce more residue, like wood or acrylic, you may find your optics need to be cleaned more frequently. Typically, optics are clear gold in color and are bright and shiny. If they are cloudy or have smudges or debris, it’s time to clean them.

Conclusion

The errors listed above are common among makers and designers that use laser engraving machines, especially those just beginning to use the equipment. But as you can see they are easily avoidable if you have the knowledge to correct the mistakes.

We help designers and makers through every step in the process of purchasing the right laser engraver, selecting the right materials to use, and understanding how to combat common mistakes, including a library of knowledge base articles and helpful support for those experiencing challenges.
