What Is Deep Laser Engraving Machine?
Fiber laser deep engraving machine is a type of laser engraving machine which adopts fiber laser souce for metal deep engraving. A fiber laser engraver is the best way to engrave metals without tools.
Fiber laser deep engraving machine is also known as laser metal engraving machine, metal laser engraving machine, laser etching machine for metal, laser deep engraving machine, deep laser etching machine, laser metal deep etching machine, metal laser deep engraving machine, metal laser engraver, laser metal engraver, laser etcher for metal.
Deep laser engraving is a type of laser engraving that involves a higher penetration of the material’s surface by the light beam produced by a pulsed fiber laser. The process is like conventional laser engraving. However, from the name, deep laser engraving is deeper, takes longer, and has a few other requirements.
Deep laser engraving requires skilled and experienced operators as the process takes a long time. You also need the right marking machine. Pulsed fiber laser markers are the only machine you can use as they are the only ones that can produce the necessary laser power to make deep marks.
What is the Deepest You Can Laser Engrave?
When we want Laser deep engraving on metals, we need to crave the metal surface bit deeper, near to few millimeters over the metal surface.
Removal of few more microns of iron from the top surface of the metals is known as Deep engraving.
Typically a standard Laser engraving will engrave the metals up to 500 microns.Generally, in the automotive industry, the metal auto parts need to be traced with correct depth. However, sometimes they are deep enough to call it deep laser engraving.
To create a fundamental difference between deep engraving and laser engraving, depth becomes the most crucial factor which makes the right graphical aesthetic over the metal components. Automotive, Medical, and aeronautical traceability standards require great depth and contrast while marking. UDI Laser marking on Medical products must not be deep. In addition, it must be dark and corrosion-resistant.

Application Scene of Deep Laser Engraving Machine
Fiber laser deep engraving machine is used for marking and engraving on metals (stainless steel, aluminum, alloy, brass, sliver, gold, titanium, iron) and nonmetal surface, such as guns, firearms, rings, bearings, gears, automotive parts, hardware and tools, aerospace components, integrated circuit chips, computer accessories, watches, electronics and communications products, home appliances, wire and cable, jewelry, adornments, necklace, bracelet and many other areas of graphics and text markup.
Do I Need to Deep Laser Engrave A Product?
Laser engraving a product should consider the type of material you are working with; deep laser engraving is no exception. No, not all products are compatible with deep laser engraving. For example, deep laser engraving is not the best laser marking process for materials that rust when exposed to wet environments, e.g., iron.
It is also unsuitable for materials with protective coatings such as stainless steel. Stainless steel is a popular iron-based alloy unaffected by corrosion. This adaptable material is strong, lightweight, and has different colors. However, it is unsuitable for deep laser engraving. While stainless steel is markable using laser beams, the process must be performed carefully to protect its ability to withstand corrosion.
Deep laser engraving is unsuitable for stainless steel because it leads to the removal of the outer layer responsible for its corrosion resistance. The outer layer is chromium oxide formed when chromium reacts with oxygen. Due to the formation of the oxide, oxygen cannot access the steel beneath, making it corrosion resistant.
It would be best if you were cautious when marking stainless steel. It is also essential to note that when the outer coating is removed, you will need to use another method such as painting to avoid corrosion. Therefore, unless you have a post-process finishing option for the product, you should consider it.
What are the important parameters of the Deep Laser engraving machine?
One of the most crucial factors to consider when selecting a laser is laser power in order to meet cycle time requirements. Although 500W is substantially faster than 100W, it is not five times as fast.
The majority of deep engraving tasks demand at least 100W. Machines with less than 100W can also do deep engraving, but you may find that the engraving time is too long.
Although it may come as a surprise, the lens is more crucial than laser power when trying to attain high engraving speeds. The laser beam’s focus is determined by the lens, and only a laser beam that is tightly focused can produce the intensity needed for deep engraving. The engraving speed can be practically doubled by using the appropriate lens. Smaller lenses work best for deep laser engraving equipment in general.
The laser beam’s scanning speed is how quickly it moves. The laser beam is kept over the same area for a longer period of time when the scanning speed is slower. You can engrave deeper and more quickly as a result of the increased energy in the area. There is a point, however, where too much power may overheat the surface and discolor it.
Your needs for quality and cycle time will determine whether you need a rapid or slow scan. Finding the ideal balance between speed and quality is the key.
Certain metals such as aluminum can be engraved faster and more profound when preheated because they can reach the temperature required for ablation faster. For example, it can simultaneously make engraver aluminum up to 40% deeper. So we need to preheat the heating plate of the laser engraver to do this.
Line width is the length of a line that a laser beam traverses before beginning a new line. The hatching speed is a brief pause of around 0.03 seconds that occurs each time the laser starts a new line. The hatching speed delay can account for more than 50% of the marking time for thin lines with a width of 1 mm. It might only rise by 10% for longer line widths of 50 mm.
In other words, the engraving speed increases with line width. For example, a small logo can be engraved at 1 mm (3) /s, while a large logo can engrave at 2.51 mm (3) /s.
How to choose a deep metal laser engraving machine?
It can be challenging to select the ideal laser engraving device for your project, particularly if this is your first time using one. When selecting a laser engraving machine, keep the following in mind.
Power output source
The type and thickness of the material you can etch are determined by the machine’s power output. Laser equipment with a power rating between 40W and 150W is required for hard materials. Deep laser engraving machines with a power output of 20W, 30W, or 50Ware are mainly relevant for simple tasks.
Accessories and Parts
When put under extreme strain, laser engravers malfunction, and the best approach to handle these problems is to make sure that replacement components are easily accessible. Check that your supplier has enough spare parts in stock.
When it comes to technical goods, inexpensive can eventually turn into pricey. Therefore, it is important that you take the time to look at each laser engraver for sale to gain insight into the different technical aspects of deep metal laser engraving machines.
Modern laser engravers are more intelligent, quicker, more accurate, user-friendly, powerful, and quieter. When choosing a laser engraver, always choose one with a large engraving area and support for all computer systems. It is crucial to take the workpiece’s material into account when selecting a laser engraver.
Power is everything when it comes to using lasers for deep metal marking. Your machine won’t be able to etch deeply enough if your laser doesn’t have a high enough power level. It may also wear out or break faster than usual because the demands on the laser are too high to sustain.
A fiber laser engraver’s power level is vital, but its power supply is also crucial. The laser source actually converts electrical power into laser power that can use for engraving.
Many lower-quality laser engravers may have weak or “jumpy” laser sources, which can sometimes lead to faulty and inaccurate engraving. You must locate a laser engraver with a steady and dependable laser source if you want the greatest results from your deep engraving task.
If you don’t think your current staff can operate a very sophisticated engraving machine, this should be a factor in your decision. You may simply be looking for a machine that is easier to use. Or a detailed and easy-to-understand guide may be included. Users can achieve many goals with an easy-to-use and stored laser engraving machine. Choose a unit that is easy to assemble and disassemble.
The best feature of modern deep laser engravers is how quickly and seamlessly they complete tasks. Examine different technologies that are available on the market besides laser technology to ensure excellent engraving outcomes. As time goes on, you might want to modify the machine you select to take into account fresh advancements in the fiber laser engraving sector.
Fiber laser deep engraving tools such as 3D oscillators for fiber lasers are just one of the beneficial new technologies. For example, if you have a laser engraver capable of employing such a galvanometer head, you may gain many capabilities. These may include the ability to engrave on uneven surfaces and the ability to engrave in depth more easily. You may also gain the ability to adjust the laser’s focus automatically.
The material you’ll be utilizing is, of course, one of the most crucial factors to take into account when determining whether or not to utilize a depth engraver. There are some materials that are easier to engrave than others. They may not require the same machine characteristics or capabilities as other, harder materials.
For example, brass and aluminum are easier to engrave in depth. However, harder metals such as steel and titanium are more difficult. Alloys such as copper, brass, and aluminum can also impact a laser’s optimal peak and average power requirements. Tool steel can have the same effect.
