Laser cutting is a relatively new manufacturing process when compared with other manufacturing processes which have their origins from the industrial revolution.
Laser Cutting uses a focused light and usually an assist gas to burn material (typically metal) into a shape which can then undergo further manufacturing processes such as pressing or countersinking.
Tube laser cutting works on a multi-axis basis where the tube is rotated by a large chuck and the laser then cuts the necessary holes, apertures and profiles. This is a highly accurate method of cutting metal tube and has many advantages over traditional "sawing" methods.
The advantages of using tube laser profiling are:
1. Repeatability: When cutting tube by hand it is often the case that there are differences from part to part as the operator may use slightly different methods each time. However, the laser will only use the settings that are programmed into the machine so there is less scope for deviation in dimensions from part to part. Repeatability is vitally important in today's manufacturing environment as the increase in lean manufacturing techniques mean that each component part has to be identical to the next. Otherwise the knock on effect of a bad assembly can lead to production delays and inevitably lost profits.
2. Speed: Lasers cut at multiple metres per second and can cut tube hundreds of times faster than via manual methods. This means that purchasers of laser cut tubes can get their parts within days rather than months reducing the amount of cash they have to keep tied up in stock.
3. Versatility: The flexibility of laser profiling tube gives far more options for designers of parts especially in the architectural and construction sectors. Complex designs can be cut into a tube which are not possible by traditional cutting methods.
4. High Volume Manufacturing: The standard supply of steel tube is in six metre lengths, managing these lengths in traditional factories was cumbersome. However, modern tube lasers allow for the loading of six metre tube in a single setup. This reduces the amount of time spent handling tubes thus aiding high volume manufacturing.
5. Formed or bent tubes cannot be cut on a traditional tube laser cutting machine as the chucks only cater for straight tubes. However, there is a large market for cutting formed tubes for automotive chassis. It is possible to cut formed tube using a 3D laser cutting technique. With this method the tube remains stationary whilst the laser moves around the workpiece making the necessary cutting.
In summary tube laser cutting uses the same techniques as flat laser cutting apart from the vital difference of the tube rotating as cut. There are many advantages over traditional tube cutting methods, however, the most important advantage is that it saves time and money in manufacturing - This is vital in today's competitive manufacturing marketplace.
Laser cutting is a technology that uses a laser in cutting different kinds of materials, mostly metals such as carbon steel, aluminum, stainless steel and copper alloys. It is widely used in the metal fabrication industry to increase cutting speed and cutting capacity, reduce production costs, increase productivity and improve cutting quality.
A laser or LASER (Light Amplification by Stimulated Emission of Radiation) is a device that generates a highly concentrated monochromatic and coherent beam of light. The light is produced through the process of stimulated emission.
Among the most commonly used laser in cutting is the carbon dioxide laser (CO2 laser), a kind of gas laser that is also used in welding. It is capable of emitting a maximum of 100 kilowatts at 9.6 µm and 10.6 µm and of cutting 20-30 m of one millimeter-thick material in a minute.
Cutting is done by aiming the energy produced by the high-power laser at a small portion of the object to be cut. That small portion is pierced first before a cut is made.
From the small hole, a cut is created either by moving the beam across the area of the material being cut, or by moving the object while the laser is kept still. One can employ both methods. As the intense beam of light strikes the part of the lazer kesimci object or material, the latter?s temperature rises, causing it to melt, burn and evaporate even without sufficient amount of heat.
Not all materials require the same amount of laser power (the rate at which energy is delivered by the light). Thicker materials need more laser power while thinner ones need lesser laser power. Usually, carbon dioxide laser cutting is done with 1,000 to 1,500 watts. Materials such as steel need more than two kW.
Compared to other metal cutting procedures, laser cutting is far more advantageous, although it has some disadvantages, too. Its primary advantages are precision, cutting quality, cutting speed and economy. Among its disadvantages is its high voltage requirement. There is also risk of getting serious burns from the laser beam.
