Laser cutting and other cutting way of comparison

The comparison of laser cutting and other cutting ways: compared with other thermal cutting method, the same as the thermal cutting process, other methods do not like a laser beam on a very small area, as a result, incision width and heat affected zone and obvious deformation. Laser cutting function of cutting metal and nonmetal. （ 1) Oxygen - Combustible ( Such as acetylene) Cutting. This method is mainly used for cutting low carbon steel, because it affect the heat input, low cutting speed, is seldom used for cutting requirements under 6 mm size precision of the material. （ 2) Plasma cutting. Cutting speed significantly faster than oxyacetylene cutting, cutting quality is poorer, trimming at the top of the round head shaped, trimming wavy, obviously prevent the arc ultraviolet (uv) radiation. It was slightly better than that of the laser cutting machine is suitable for cutting thick steel plate and the beams of high reflectivity of aluminum alloy, etc. （ 3) Die. Mass production parts die with the method of low cost, short production cycle. But it is very poor, adapt to changes in the design of the new mould need long time to design, high cost, for medium and small-scale production, the characteristics of laser cutting will be fully displayed. In addition, the laser program-controlled cutting facilitate artifacts closely arranged, save material, die and you will need to reserve materials around each artifact. （ 4) Section cutting complex parts. Under normal circumstances, the punch press often rush cut much bigger than the mould size of workpiece, some of the artifacts are very complex, this leads to trimming are many Beckham shell parts, need a second preliminary processing and repairs. Another punch can form incision is much wider than laser cutting machine, produce a large number of scrap iron. （ 5) Sawing. Cut thin metal, its speed significantly slower than laser cutting, laser as a flexible and no contact, shape cutting tools, from material to any one of the cut in any direction. Is hard to do this, sawing. （ 6) Electric processing. General, favorable electricity spark and electrochemical corrosion or fusion effect processing, two methods used for fine machining of hard materials, roughness of incision is better, but the cutting speed is slower than the speed of laser cutting machine to a few orders of magnitude. ( 7) Water cut. But many cutting metal materials, but the cost is very high.
