What is the max. thickness of the metal that 500W fiber laser cutter is able to cut?

Fiber laser cutter is a cutting device with superior performance. In thin metal plate processing sector, fiber laser cutter has always considered to be the fastest laser processing equipment. However, different kinds of metals have different kinds of features, so fiber laser cutters will have different processing abilities to those metals.

Theoretically speaking, when fiber laser cutter increases by 100W power, it can cut 1mm more thick metals. Therefore, 500W fiber laser cutter is supposed to be able to cut 5mm metals. However, the actual situation is quite different. When the fiber laser cutter is running, the electric energy turns into luminous energy and then turns into heat energy. During this process, there has to be energy loss. Therefore, in actual cutting, the theoretical value can not be reached. So how is the actual cutting ability for 500W fiber laser cutter? 

1.For copper and aluminum, since they are highly reflective material, it’s quite hard for fiber laser cutter to cut them (the reflection is harmful to the fiber laser source). Therefore, the maximum thickness for fiber laser cutting is around 2mm;
2.For stainless steel, it is quite hard. The maximum thickness for fiber laser cutting is around 3mm;
3.For carbon steel, since it contains high volume of carbon, it is relatively soft, which makes it much easier for cutting. The maximum thickness for fiber laser cutting is around 4mm. 

To guarantee the best performance of 500W fiber laser cutter, the key is to provide stable temperature control. S&A Teyu dual circuit laser water chiller is applicable to cool down 500W fiber laser cutter effectively. This fiber laser chiller has two independent water circuits, so it can provide effective cooling for the fiber laser and the laser head at the same time.

Laser welding, a promising technique which expects to have more and more applications

 Laser has a unique advantage in welding aluminum alloy, copper alloy, titanium alloy and other kinds of metal materials and it is now gradually replacing traditional welding technique. In the past 10 years, laser welding machine has already been widely used in battery, hardware, jewelry, 3C products, new energy automobile and other industries that is closely related to people’s life. This kind of popularity results from 3 outstanding features of laser welding machine.

First, efficiency. Laser welding machine is 2-10 times faster than traditional welding. That is because laser welding machine posts high energy laser light on the material surface, which is very efficient.

Second, quality. Laser welding machine is more superior than traditional welding technique in welding quality. That is because laser welding machine has small heat affecting zone and the work piece it process has no deformation or crater with smooth edge. And more importantly, it doesn’t require post processing. Therefore, the yield of laser welding machine is often very high.

Thirdly, high automation and eco-friendliness. Laser welding machine users won’t have to wear insulation shoes or thick gloves when holding the protection mask and the electrode holder at the same time. 

After all these years, laser welding technique has been well recognized by users. For the time being, laser welding machine can be divided into:
- Laser welding machine that uses multiple heat source and is suited for materials with medium level thickness;
- Laser welding machine oriented to weld thin metal materials;
- Laser welding machine oriented to weld highly reflective and low absorptive materials;
- Laser welding machine oriented to weld transparent materials with high precision

From the above category, laser welding machine can work on non-metal as well as metal materials. For non-metal laser welding machine, it is often equipped with CO2 laser. While for metal laser welding machine, fiber laser is often the major laser source. Either CO2 laser or fiber laser, they need to maintain stable temperature so that the laser beam quality can be guaranteed. S&A Teyu is a laser cooling solution provider with 19 years of experience. The recirculating laser chiller it produces is suitable for cooling CO2 laser and fiber laser of different powers.

Femtosecond laser can take the challenge of precision micromachining

As laser technology develops, laser source is heading towards faster pulse, higher energy and shorter wavelength. This has brought revolutionary progress to laser processing industry. By revolutionary progress, it means ultrafast pulse laser processing can reach much higher precision than the long pulse laser processing. The highest precision could reach submicron or even nanometer level. In addition to cutting and drilling, ultrafast pulse laser can also perform modification inside the materials.

Ultrafast laser can nearly work on any kinds of materials. For super-hard, easily broken, high melting point, easily explosive materials, it has superior advantages that other processing methods don’t have. 

Since femtosecond laser features ultrafast speed and ultrahigh peak power, when it is used for material processing, it can inject all its energy with very fast speed to very tiny area. The sudden high energy density deposits and then the absorption and moving way of the electronics changes. This has completely changes the interaction way of the laser and the materials, making femtosecond laser become an ultrahigh precision and ultrahigh spatial resolution processing method in micromachining. 

Femtosecond laser is a kind of ultrafast laser. As is known to all, ultrafast laser is sensitive to temperature changes. Consistent temperature is the key to maintain the precision of ultrafast laser. S&A Teyu CWUP series ultrafast laser portable water chilleris applicable to cool different kinds of ultrafast lasers, including femtosecond laser, nanosecond laser, picosecond laser and so on. This series water chiller features ±0.1℃ stability, indicating very precise temperature control.

Can laser marking machine work on cardboard box?

The continuous development of laser technique encourages wider applications of laser marking machines in different industries, such as mobile phone, jewelry, hardware, kitchenware, tools & accessories, automobile parts and so on. Since so many stuffs can be laser marked, some people ask, “Can laser marking machine work on cardboard box?”

Well, that is for sure. Using CO2 laser marking machine can mark the patterns and characters on the cardboard box very clearly. The working principle of CO2 laser marking machine is that the heating up the surface material which then evaporates and the inner materials will show to form the long-lasting marking. Anything can be laser marked, including delicate characters, patterns, logos, time and so on. Comparing with traditional inkjet printing technique, CO2 laser marking machine features more clear marking, faster speed, higher yield, less pollution and longer lasting quality.

Since laser marking machine can laser mark many different kinds of contents, it has the advantages that many other equipment doesn’t have. 

Cardboard box is a product that people are very familiar with. General cardboard box is light yellow. But some of them has with colors with or without membrane. Now let’s talk about laser marking on these two types of cardboard boxes. 

The light yellow cardboard box. This kind of cardboard box can be laser marked by CO2 laser marking machine, for CO2 laser marking machine is the most suitable and the cheapest laser marking machine.

The colored cardboard box. If it is without membrane, fiber laser marking machine can be used on the colored part. If it is with membrane, CO2 laser marking machine should be used. 

CO2 laser marking machine is powered by CO2 laser glass tube. CO2 laser glass tube will easily burst if it gets overheating. To prevent this from happening, it is necessary to add a small laser water chiller. And many users would choose S&A Teyu CW series chiller models. S&A Teyu CW series portable water chillers, especially the CW-5000 and CW-5200 models, are characterized by ease of use, compact design, low maintenance and easy installation.
