Today, Xiaobian sister will popularize the relevant knowledge about laser cutting machine and wire cutting technology. It is widely used in daily life. Let's take a look!
The latest mainstream laser cutting equipment is mainly fiber laser cutting machine and YAG laser cutting machine. At this stage, the CO2 laser cutting machine is mainly used for cutting thick plates, but it can cut non-metallic materials. The first two are mainly for the cutting of thin metal materials, and the latter is used for thick plate cutting and non-metal cutting (the non-metal materials are not compared here). The main feature of laser cutting is fast cutting speed, which is famous for good cutting quality and low processing cost.
Wire cutting can only cut conductive materials, which limits its scope of application, and requires cutting coolant during the cutting process. Therefore, some non-metallic materials, such as leather, which are less than point, afraid of water, and afraid of cutting fluid pollution can not achieve wire cutting. The advantage is that one-time forming cutting of thick plates can be achieved, but the cutting edges will be rough. Current wire cutting is divided into fast-moving and slow-moving according to the type of wire used. Fast-moving uses molybdenum wire, which can be used for multiple cutting. Slow-moving uses copper wire, which can only be used once. Of course, copper wire is better than molybdenum wire. Much cheaper. Another fast-feeding equipment is much cheaper than the slow-feeding equipment. The price of the slow-feeding equipment is about five to six times that of the fast-feeding equipment.
Laser cutting uses high-energy-density laser beams to irradiate high-temperature melted cuts to achieve cutting. The metal material to be cut must not be too thick, otherwise the heat-affected zone may be too large and even the cutting cannot be achieved. The laser cutting application covers a very wide area. Most metals can be cut without being limited by shape. The disadvantage is that they can only cut thin plates.
Wire cutting molybdenum wire is used to produce high-temperature cutting material to be cut. It is usually used as a mold. The heat affected zone is relatively uniform and small. It can realize the cutting of thick plates, but the cutting speed is slow, only conductive materials can be cut, and the application area is small. Because there are consumables, the processing cost is higher than that of laser cutting.
The two have mutual advantages and can basically form complementarity. However, with the development of industrialization requirements, the processing enterprises' increasing demand for large-scale production also means higher requirements for work efficiency, so high speed, High-quality, low-cost laser cutting processes are more suitable for modern production needs, and wire cutting is gradually losing competitiveness in the market.
