According to the consumption analysis of China's steel industry, the main application industries of steel are construction, machinery, automobiles, and energy, followed by shipbuilding and home appliances. Most of the plates used in these industries are medium-thick plates.
Traditional medium-thick plates are processed by plasma cutting, flame cutting, water cutting, wire cutting and other processing methods, but there are some problems such as plasma cannot cut small holes, and poor dimensional accuracy, large thermal impact, cannot cutting small parts, wide weld seam, waste of materials. Flame cutting can only cut carbon steel, not non-ferrous metals, and the cutting speed is slow. Water cutting has large pollution to water quality. Wire cutting speed is slow and consumables are large. The wear of punch grinding tools is large, and the cost of mold opening is high.
Fiber laser cutting can make up for the shortcomings of traditional cutting, especially the development of 10,000 watt-level laser cutting, which solves the limitations of laser cutting in thick plate cutting in the past, and is favored by more and more sheet metal processing end users.
