Comparison of two cutting processes between laser cutting machine and wire cutting
Laser cutting: The latest mainstream laser cutting equipment is mainly fiber laser cutting machine and CO2 laser cutting machine. At present, the CO2 laser cutting machine is mainly used for the cutting of thick plates, but it can realize the cutting of non-metallic materials. The first two are mainly used for the cutting of plates, and the latter is used for the cutting of thick plates and non-metallic cutting (non-metallic materials are not compared here). Laser cutting has the characteristics of fast cutting speed, good cutting quality, and low processing cost.
Wire cutting: Wire cutting can only cut conductive materials, which limits its application and requires cooling fluid during the cutting process. Therefore, some non-metallic materials such as leather are not enough, and materials that are afraid of water or cutting fluid pollution cannot achieve straight cutting. The advantage is that the thick plate can be cut at one time, but the cutting edge will be very rough. Current wire cutting can be divided into fast routing and slow routing according to the type of wire used. The fast-moving thread can be cut multiple times, and the slow-moving thread can only be cut once. Of course, copper wire is much cheaper than molybdenum wire. Another fast-moving device is much cheaper than a slow-moving device, and the price is about five to six times that of a fast-moving device.
Laser cutting is achieved by using high-temperature molten cutting materials produced by high-energy density laser beam irradiation. The metal material to be cut should not be too thick, otherwise the area affected by the heat will be too large, or even impossible to cut. Laser cutting has a wide range of applications. It can cut most metals and is not limited by shape. The disadvantage is that it only cuts plates.
Molybdenum wire for wire cutting, high temperature cutting material produced by electrification is cut, and it is usually used as a mold. The area affected by heat is relatively uniform and small. It can cut thick plates, but the cutting speed is slow, only conductive materials are cut, and the application is small. Because there are consumables, the processing cost is higher than laser cutting.
Advantages, the two can basically complement each other, but with the needs of industrial development, the increasing demand of large-scale production and processing enterprises means higher requirements for efficiency, so In metal cutting, the high-speed, high-quality, low-cost laser cutting technology is more suitable for the needs of modern production, and has gradually lost its market competitiveness.
