What Is The Difference Between The Process Of Hot Cutting And Laser Cutting?

       What is the difference between the process of hot cutting and laser cutting?
　　 The difference between laser cutting and hot cutting:
　　  1. Oxygen-combustible (such as acetylene) is cut. This method is mainly used for cutting low carbon steel. Due to its large heat input effect and low laser cutting speed, it is rarely used to cut materials with precise dimensions below 20 mm.
　　  2. Plasma cutting. The cutting speed is obviously faster than that of oxyacetylene cutting, but the cutting quality is poor, the top of the trimming is rounded, the cutting edge is obviously wavy, and the ultraviolet radiation generated by the arc is also prevented. It is slightly better than the laser cutting machine in that it is suitable for cutting thick steel plates and aluminum alloys with high beam reflectivity.
　　  3, die punching. The mold punching method for mass production of parts has a low cost and a short production cycle. However, its adaptability to design changes is very poor. New molds require long-term design and high cost. For medium and small-scale production, the characteristics of laser cutting will be fully displayed. In addition, laser program-controlled cutting facilitates the close alignment of the workpiece, saving material, while the die-cutting requires material to be placed around each workpiece.
　　  4. Complex parts are punched and cut. In general, punches often have to cut a workpiece that is much larger than the size of the mold. Some of the workpieces are still complicated, which results in a number of small shell-like edges on the cut edge, requiring a second preparatory finish. In addition, the punch will form a much wider slit than the laser cutter, producing a large amount of iron filings. The above cutting method cannot be applied to a very small area like the laser beam of the laser cutting machine, resulting in a wide slit, a large heat affected zone and a significant deformation of the workpiece. Laser cutting machines can cut non-metals, while other thermal cutting methods do not.
