Advantages of laser cutting machine processing

Sep. 17, 2019

Compared with other thermal cutting methods, laser cutting machine has a small working area and a small incision. Other thermal cutting cannot be applied to a very small area like a laser beam, resulting in a wide slit, a large heat affected zone and a distinct workpiece. Deformation. Laser cutting machines can cut non-metals, while other thermal cutting methods do not. The following is a comparison of different cutting equipment

1. 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.

2. Oxygen-combustible (such as acetylene) is cut. This method is mainly used for cutting low carbon steel. Due to its high heat input and low cutting speed, it is rarely used to cut materials with a size requirement below 20 mm.

3, die punching. The mass production process uses a die punching method with low cost and 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 machines 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 many small shell-like edges for the trimming, requiring secondary preparation and refurbishment. In addition, the punch will form a much wider slit than the laser cutter, producing a large amount of iron filings.

5, electrical processing. In general, there are two methods of electric sparking and electrochemical machining using electrocorrosion or melting effects, which are used for fine processing of hard materials, and the slit roughness is good, but the cutting speed is several orders of magnitude slower than that of the laser cutter.

6, sawing. Cutting thin metal is significantly slower than a laser cutter, and the laser acts as a flexible, non-contact, profiling tool that cuts from any point in the material to any direction. At this point, sawing is difficult to do.

7, water cutting. Many metal materials can be cut, but at a high cost.
