Aluminium snijtechnieken: Van basis tot geavanceerde methoden
aluminium gietwerkIn numerous industries, such as the automotive or aerospace industries, electronics or construction, aluminum cutting is a significant process. The lightweight strength of aluminum and its corrosion resistance have made it a preference to manufacturers as well as to do-it-yourselfers. However, aluminum has to be cut with proper tools and a defensible strategy, so as to attain perfect cuts without destroying the material. Being a hobbyist or a professional fabricator, this knowledge will make your choices better, mistake-free, and the most excellent results in every aluminium cutting project. The hand tools, power saws and more recently, more sophisticated such as the aluminum laser cutting, are some modes of aluminum cutting. Laser-cut aluminum is a new and currently fast-growing alternative to classic techniques (that can complement more basic shapes). In case you intend to incorporate in your next project the so-called aluminium laser cutting, we will also present some design suggestions and cost-conscious recommendations. Here in this article, we will see all about what you need to know about the process of aluminum cutting, starting with the ancient ways of doing it, to the new form of laser process. We will discuss the advantages and disadvantages of each of the techniques, typical issues of the so-called laser cut aluminium, safety precautions to consider and which tools and equipment will be required. What Is Aluminum Cutting? Cutting of aluminum material is the act of shaping, trimming or cutting aluminum material pieces, or proportioning the material into particular sizes or shapes through different tools and strategies. Since aluminium is light, strong, and corrosion-resistant, it finds its applications across a variety of industries: construction, aerospace, automotive, electronics, home DIY projects, etc. A lot of cutting methods of aluminium exist, depending on the thickness of the material, the shape wanted, or the required accuracy. Possible ways are: Pros and cons can be attributed to both of them, yet about the intention of cutting aluminum, there can never be a difference, and that is to get clean, precise and safe cuts with minimum waste and maximum productivity. Some of the Main Properties of Aluminium We cannot ignore the material before we start discussing the process of cutting it in the name of aluminium cutting. Aluminium is soft in its strength and more robust than numerous metals. It transfers heat fast, and this may be a source of challenge during the use of the cutting tools. Left unchecked, aluminium can clog up tools or give a poor finish. These properties have led to the involvement of various methods that facilitate in the cutting of aluminum in a better and precise manner. The selection of the method is based on the thickness of material, precision needed and the tools available. Conventional Names for Aluminium Cutting Before the invention of advanced machines and laser technologies, aluminium cutting was performed using primitive, manual methods. Although such techniques cannot bring the accuracy of the modern instruments, they are still commonly used in small projects, repairs and where cheapness and simplicity are essential interests. What about the old ways of aluminium cutting that have survived the test of time? 1. Hacksaws A hacksaw is a low mechanism, hand operated equipment manufactured to cut aluminium. It involves finely toothed blade which cuts soft metals. It is suitable in thin sheets, pipes or bars and cutting straight cuts on small aluminum pieces. Advantages Disadvantages 2. Aviation Shears and Tin Snips Tin snips, or aviation shears, can be used on thin aluminium. They are available in straight-cut, left-cut and right-cut versions of these scissors-like tools designed to work in sheet metal and, therefore, allow working with curves and angles that are very tight. Advantages Disadvantages 3. Handheld Nibblers A portable nibbler nips off tiny bits of the aluminium as it travels over a line. It is perfect to cut curves, circles, or various patterns on sheet aluminium. Advantages Disadvantages 4. Jigsaws A jigsaw is a power type of tool which can move in the up and down direction. it can cut through aluminum sheet or tubing when supplied with a fine-tooth metal blade. Jigsaws are quite handy in cutting customized shapes or curves. Advantages Disadvantages 5. Circular Saws If a thicker sheet of aluminium is to be cut, a non-ferrous metal blade section can be mounted on a circular saw. These are the tools which are commonly used in construction and fabrication to cut straight lines. Advantages Disadvantages 6. Bandsaws A bandsaw is a type of saw and incorporates a continuous looped blade that makes it suitable when cutting thicker stock and when straight lines or Geometry are needed. A lot of metal shops use bandsaws due to their flexibility and speed. Advantages Disadvantages Best Traditional Cutting Practices Typical Issues of Laser Cutting Aluminium 1. Reflective Surface On older CO 2 machines, lasers are reflected by aluminium, and fewer watts irradiate the material.Solution: Go with fibre lasers and adjust the angle or coat it. 2. Rough or hough Edges The edges are scorched or jagged on occasion.Fix: An alternative would be to use nitrogen rather than oxygen in the fixing phase, also to change the laser speed and power. 3. Heat Warping Aluminium can conduct heat very fast, and therefore, thin layers can get curved or warped during the cutting process.Solution: Employ less power and speedier speeds. Crimp the workpiece. 4. Sticky residue, Dross Molten aluminium may attach to the bottom edge, resulting in a rough termination.Fix: Run high pressure of gas and maintain a clean as well as straight nozzle. 5. Unfinished or Unsuccessful Cuts The laser, in some cases, does not pierce well, or it leaves parts incomplete.Repair: Wash the metal, upgrade the software and check all worn components. 6. Discolouration and Oxidation Oxidation tends to darken or wear out a cut surface.Fix: clean the edges afterwards (if necessary) with nitrogen gas. 7. Cracks on the Edges Cuts that are very fast or hot may produce minute cracks and make the aluminium weak. New Technologies: Laser Cut Aluminium In laser-cut aluminium, a
