Nowadays, the world is evolving with new ideas, and people are seeking more precision work. The type of machinery in different fields is also changing. A laser wood stripping machine is an excellent example of this. Previously, people used to use traditional tools, which were slow and less accurate. Especially when cleaning wood surfaces, traditional tools often fail to offer high precision.
As the name implies, a laser wood stripping machine is used to strip materials from the surface of the wood. Most manufacturers prefer this technology for precision work and safety. It is primarily used for cleaning purposes and is often referred to as a laser paint removal machine.
A laser wood stripper not only works on wood but also on plastics, ceramics, concretes, and other non-metallic materials. Even on metals, you can use it to remove coatings and paints. It is a convenient and efficient device for all general-purpose cleaning work.
There are different types of lasers for removal purposes. Each laser is specifically designed to work optimally for a particular application. Here, CO2 lasers are the most commonly used lasers on wood surfaces. Fiber lasers may not yield satisfactory results for this work. However, you might also opt for diode lasers. Well, it mainly depends on what you need for your projects.
Introducing Laser Stripping Wood
Stripping means removing all coverings. Consequently, a stripper machine is usually used to remove coverings. In terms of stripping wood, it means cleaning the surface of the wood. A laser wood stripping machine is a cleaning device that removes paint, coating, or other contaminants from wood.
Why laser? Why not use chemicals or other mechanical tools? In a sentence, laser stripping wood is much safer than any other method. Mechanical stripping damages the underlying surface. On the other hand, chemical cleaning changes the properties of the wood surface. So, none of them can offer you a safer option than a laser wood stripper.
Laser wood stripping is also a clean, quick, and precise way. Additionally, it offers multiple unique features that are particularly helpful for stripping. The laser stripping machine for wood does not require any chemical substances. Also, it is a contact-free method, which is far safer for the underlying materials. Therefore, it works better with old, thin wood, making it ready for carving and painting.
Many people utilize these machines for restoration, pre-treatment, or sign-making purposes. Additionally, if you need to repair your furniture or prepare it for painting, the machine can assist you along the way. However, to get a better result, you need to know what type of wood you are using. It is essential to note that each type of wood reacts differently to laser treatment. Therefore, you must adjust your laser stripper or cleaner settings before using it.
How Does a Laser Wood Stripper Work?
The laser wood stripping machine uses a powerful laser beam during the process. The beam creates an intense light and attacks the surface area. You can fix the area where the beam will approach. After heating up with a large amount of power, it gradually evaporates the unwanted layer from the surface. As you are aware, it doesn’t require any chemicals or harmful substances, so there is no wear and tear.
Also, you can control the whole process through a computer. Fix up your parameters according to your task. The typical power range for this ranges from 0.1 to 10 MW/cm², and the scan speed ranges from 100 to 1000 mm/s. The pulse frequency can range from 20 kHz to 100 kHz. It may require 1-5 passes to finish the process correctly. People find it beneficial because it enables flexibility when working on several types of wood or coatings.`
Overall, it’s a highly controlled process. You can easily balance everything accordingly. From laser ablation intensity to efficiency, with proper finishing.
Mechanical Stripping Vs Laser Stripping: What’s the Difference?
Mechanical stripping involves using sandpaper, grinders, or scrapers to remove coating from the surface. The process is comparatively cheaper than using laser technology. However, it will lead to significant losses in the long run.
Following the process can easily damage the wood surface. Besides, you will need more time to complete the task. If you lack expertise in this area, you may end up with an uneven surface finish. Eventually, it can be messy and tiring because of rubbing and cutting.
On the other hand, laser stripping is easy to work with. It doesn’t need your hands to do the work. All you need to do is set the laser settings and position the machine correctly. The rest of the work is up to the machine itself.
Laser paint stripping machines for wood are also a rapid process. Unlike mechanical tools, it operates with high precision and is effective for a wide range of wood types.
Why Should You Use a Laser Wood Stripping Machine?
There are several reasons why you should use a laser wood stripping machine. You already got some hints from the above two sections. However, let’s summarize it one more time.
First, laser stripping machines offer efficient and accurate cleaning. No other methods can reach the accuracy that laser strippers can.
Second, the laser wood stripping machine is an environmentally friendly method. It doesn’t involve chemicals, so it is much safer for the environment.
Third, the laser paint stripping machine is a versatile tool. It also works on metals, plastics, ceramics, concretes, wood, and even glass.
Fourth, laser wood stripping is a computer-controlled process. The laser parameters and speed are fully adjustable. You can decide the appropriate power settings based on your workpiece types.
Finally, the laser wood stripper is ideal for use on delicate components. While traditional methods cannot ensure safety for delicate components, a laser machine can.
How Much Does a Laser Stripping Machine for Wood Cost?
The prices of laser machines vary depending on the type of coating, the type of wood, and the power. If you want to do light stripping or hobby use, then 5 to 20W diode lasers will be good for you. The cost will be between $300 and $1,000.
For DIY or light commercial work, CO₂ lasers are suitable and cost between $500 and $4,000. Otherwise, if you require deep stripping, the price will be $4,000–$10,000 or more. Most business owners use these CO₂ lasers for large-quantity work.
Things to Consider When Choosing a Laser Wood Stripping Machine
When purchasing a laser wood stripping machine, consider a few key factors. Firstly, consider the types of wood and coating thickness you want to work with. Thereafter, consider the power, ease of use, portability, durability, and lastly, cost. In the following sections, we will discuss the topic in four key points.
#1 Does the Type of Laser Matter?
Yes, the type of laser used is a significant factor in the selection process. You will have different options to choose from. Among them, CO2 lasers are considered the most suitable for cleaning. The CO2 laser wavelength is ideal for removing paint, coatings, or contaminants. For more versatile work, you may also opt for diode lasers.
Fiber lasers are not suitable for cleaning wood. It can easily burn or damage your wood. We always recommend it for metal stripping or cleaning rust. In contrast, pulse lasers use a short burst of energy in the process, suitable for precision woodwork.
#2 What Laser Power Should You Choose for Laser Stripping Wood?
Every material requires a specific level of laser power for effective cleaning. The laser power required to clean paint is not the same as the laser power needed to clean coatings. So, determine the power based on your wood thickness or coatings. For example, power levels ranging from 20 to 100W are suitable for detailed work and thin to medium coating applications.
Higher power machines are excellent for thick coatings or paintings. Most people prefer higher power levels (100W to 1000W) for large surface areas. Using it will increase the speed of your work, cut errors, and save time. Therefore, consider all factors and make your decision accordingly.
#3 Manufacturer’s Flexibility & Ease of Communication
When purchasing a laser machine, having reliable customer support and service is essential. Ensure the manufacturers have a good reputation for their products & services. They should answer the questions quickly and clearly. The company must be capable of providing good after-sales services with care. If there are any software issues or part replacements, the company should assist in resolving these problems.
Additionally, verify if they provide a user-friendly manual and training sessions for beginners. Good customer reviews play a significant role here. This way, you can get your desired manufacturers.
#4 Is the Working Area Enough?
The working area typically matters for an automated laser wood stripping machine. For a handheld laser, it usually is not that important.
