As a new processing method, metal laser cutting is widely used in processing industries such as metal and non-metal materials due to its advantages such as precision processing, fast processing speed, simple operation, high degree of automation, and intelligence.
Compared with traditional cutting methods, metal laser cutting is not only cheap and consumes less, but also because laser processing puts no mechanical pressure on the workpiece, the effect, accuracy and cutting speed of the cut products are very good. Good, and it also reduces processing time. , reduce processing costs, improve workpiece quality, safe operation, simple maintenance and other characteristics. In recent years, metal laser cutting processing has developed very rapidly, gradually replacing traditional processing methods.
In addition to general metal laser cutting processing, high-speed and high-precision metal laser cutting processing, large-format thick plate metal laser cutting processing, three-dimensional CNC metal laser cutting processing, aerospace non-ferrous metal laser cutting processing are very important to the jet cutting system. The demand is also increasing day by day.
Therefore, metal laser cutting processing mainly develops in the following aspects:
1. High-speed, high-precision, and high-power metal laser cutting is one of the development directions of metal laser cutting;
2. With the increase in laser power that can be used for metal laser cutting, metal laser cutting processing is developing from light industrial plate processing to heavy industrial thick plate and large-size workpiece cutting.
3. In order to meet the needs of automobile, aviation and other industries for three-dimensional workpiece cutting, efficient, high-precision, multi-functional and adaptable three-dimensional metal laser cutting processing is a new development direction; metal laser cutting units are automated and unmanned Improve productivity and save labor. .
Cutting unit (FMC) and unmanned and automatic; laser With the continuous improvement of metal laser cutting processing, a complete set of small-sized, functional devices that closely integrate laser, power supply, host, control system and cooling water circulation device has emerged. Complete range of compact metal laser cutting processes. With the rapid popularization of metal laser cutting technology applications, the market space continues to expand.
The development focus of China’s CNC metal laser cutting technology and equipment should mainly focus on the following aspects: the development of high-speed and high-precision CNC metal laser cutting equipment; the development of high-precision three-dimensional metal laser cutting equipment; the development of large-format thick plate metal laser cutting equipment. Jet cutting equipment; develop cutting equipment for special industries.
Therefore, the key common technologies that need to be broken through in CNC metal laser cutting mainly include the following aspects:
1. Mechanical structure design and driving technology
2. CNC technology
3. High-power laser beam transmission focusing technology and metal laser cutting proprietary technology
4. Dedicated CAD/CAM software system
5. Design and manufacture of high-power metal laser cutting heads for thick plates 6
Research on metal laser cutting process CNC metal laser cutting equipment has extremely wide market demand in domestic and foreign markets
There is a certain gap between my country and foreign countries in CNC metal laser cutting technology and equipment, but it has developed rapidly in recent years. The future development direction should be high-speed and high-precision metal laser cutting, large-format metal laser cutting, 3D metal laser cutting, and special material metal laser cutting. In order to meet the growing market demand, we conduct research and development of key common technologies in cutting and other fields and form industrialization.
