Laser cutting is among the most economically efficient, flexible and precise ways of cutting metal and is now more effective and simpler than ever. They are used wherever complex designs have to be processed accurately, quickly and with as little force as possible. The process is particularly popular in the industrial sector as it can be used to machine almost any metal. The powerful and cost-effective laser cutters from JustLaser are ideally suited for cutting metal up to 6 mm thick (ideally) and win people over with their low investment risk and high levels of productivity. Higher processing speeds and typical material strengths are between 0.5 mm to around 4 mm.
Laser cutting is a thermal cutting process in which the metal to be cut is removed from the cutting gap by a continuous or pulsed laser beam. The material is cut according to specified patterns which are traced by a precise laser beam. The efficient CO2 laser or fibre laser are usually used for this. At JustLaser, you’ll find the ideal laser cutter for cutting metals 6 mm or 5 mm thick and made from aluminium, sheet metal and copper or acrylic. In laser cutting, basic distinctions are made between three different methods, depending on the material thickness and the requirements of the workpiece:
Laser flame cutting is carried out with the help of the cutting gas oxygen. This ensures exothermic oxidation processes, i.e. the energy released as heat by the combustion of metal supports the cutting process. This method is suitable for manufacturing parts quickly.
In laser fusion cutting, inert gas is blown into the cutting joint and thus prevents or severely inhibits reactions with atmospheric oxygen. The cut edge and the surrounding metal is also cooled. It forms a low-oxide cut edge which is beneficial for all workpieces which should not be subjected to post-processing, or where no material change is desired.
Sublimation cutting is done without cutting gas and is used for thin metal sheets (up to approx. 3 mm thick). The laser causes the material to be vaporised, which produces a fine, often burr-free cutting gap.
In contrast to nibbling, milling or punching, cutting metal up to 6 mm thick with JustLaser laser machines has some great advantages. Extremely narrow cutting joints of high precision and quality can be produced with the laser. That means even the finest designs can be produced on a wide variety of inorganic materials. The method produces low distortion and, depending on the material, hardly any post-production will be necessary. Furthermore, this cutting process is a particularly cost-effective method – as the process is contactless, laser machines are not subject to tool wear. As the laser doesn’t exert any mechanical force (more precisely, there is a force that is always negligible due to photon pressure) on the workpiece, there is no need for clamping, meaning that no mechanical deformation occurs.
The benefits of laser cutting at a glance:
All metallic materials used in industrial processing that can be cut safely and to a high quality are suitable for laser cutting of metal up to 6 mm thick, the majority of which are aluminium, stainless steel and structural steel:
Whether you use a fibre laser, another solid-state laser or a CO2 laser for cutting metal up to 6 mm thick is dependent on the properties of the material in question and the thickness of the sheet.
Construction steel is the most common cut material in the industrial sector. In 2D laser cutting of structural steel, CO2 lasers are usually used to produce gears, covers or bezels. Both solid-state lasers and CO2 lasers are used for 2D laser fusion cutting or flame cutting stainless steel and non-ferrous metals. For gold, silver and platinum, solid-state lasers are chosen because their significantly lower wavelength of about 1,062 nm is better absorbed by the precious metals. At JustLaser, we can also offer the right solution for this. When cutting or engraving precious metals, it (obviously) makes economic sense to recycle the content of the extractor filters.
When it comes to highly precisely cutting metal up to 6 mm thick, trust in the laser machines from JustLaser! With a low investment risk in comparison to other devices, you can acquire a high-quality product which guarantees short set-up times, flexibility, a long service life and greater productivity. JustLaser is setting new standards!
