3D laser cutting machine Specification

The working mechanism of 3d laser cutting

　　Laser cutting is the use of high power density laser beam scanning over the material surface, in a very short period of time to heat the material to thousands to tens of thousands of degrees Celsius, so that the material melting or gasification, and then high pressure gas will melt or gasification material blown away from the slit, to achieve the purpose of cutting materials.

　　The working mechanism of 3d laser cutting is relatively different from that of 2d laser cutting. 3d laser cutting requires constant adjustment of laser cutting head position to ensure that the laser cutting head is always perpendicular to the workpiece surface, so as to obtain excellent cutting quality. In actual production, 3d laser cutting program compilation requires the 3d modeling of parts, and then the introduction of 3d programming system generation path, and manual adjustment according to the characteristics of parts, tooling features, to avoid cutting head collision, complex operation, large workload. Since the cutting head of 3d laser cutting machine is equipped with capacitive sensor, which can automatically adapt to the shape of parts and always keep a certain distance from parts for cutting, the two-dimensional programming system of 3d laser cutting machine can meet the production needs only when the surface of parts does not change dramatically.

　　Advantages and disadvantages of 3d laser cutting

　　Through the production practice, 3d laser cutting has the following advantages: (1) good flexibility, can adapt to different shape of the workpiece cutting processing. (2) high precision, can meet the aluminum alloy emu, stainless steel subway and other products manufacturing precision. (3) high economic benefits, can replace the traditional manufacturing process of trimming die and punching die, the process is simple, short manufacturing cycle, fast cutting speed, small slit width, high processing quality, can greatly reduce the cost, shorten the research and development cycle of new models, has good economic value and application prospects.

　　Development trend of 3d laser cutting

　　1. With the development of laser to high power and the use of high-performance CNC and servo system, the use of high power laser cutting can achieve high processing speed, while reducing the thermal impact zone and thermal distortion; The thickness of the material that can be cut is further increased.

　　2. According to the influence of laser cutting parameters, the processing technology was improved

　　3. Laser cutting will be highly automated and intelligent. CAD/CAPP/CAM [4] and artificial intelligence are applied in laser cutting to develop a highly automated multi-functional laser processing system.

　　4. Develop to the multi-functional laser processing center, integrate the quality feedback after laser cutting, laser welding and heat treatment, and give full play to the overall advantages of laser processing.

　　5. With the development of Internet and WEB technology, the establishment of web-based network database, using fuzzy reasoning mechanism and artificial neural network to automatically determine the laser cutting process parameters, and remote access and control of the laser cutting process has become an inevitable trend.

　　6. Three-dimensional high-precision large-scale numerical control laser cutting machine and its cutting technology, in order to meet the needs of three-dimensional workpiece cutting in automobile and aviation industries, three-dimensional laser cutting machine is developing towards the direction of high efficiency, high precision, multi-function and high adaptability.

　　Application range of laser cutting

　　Three-dimensional laser cutting is widely used in sheet metal processing, metal processing, advertising production, kitchen utensils, automobiles, lamps and lanterns, saw blades, elevators, metal crafts, textile machinery, grain machinery, glasses production, aerospace, medical equipment, instrumentation and other industries. Especially in the sheet metal processing industry has replaced the traditional processing methods, favored by industry users.

　　Machinable materials: stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized plate, galvanized version, pickling plate, copper, silver, gold, titanium and other metal plates and pipe cutting.

　　Application in aluminum alloy emu manufacturing. 3d laser cutting is mainly used for cutting jacket of driver's cab skin of aluminum alloy emu. The driver's cab skin is an aluminum alloy sheet with curved surface structure, which is especially suitable for 3d laser cutting. After forming, the production efficiency and cutting precision of 3d laser cutting are significantly higher than that of linework sawing with band saw machine.

　　Application in the manufacture of stainless steel subway. Three-dimensional laser cutting is mainly used in the eye hole and notch processing of the upper beam of the stainless steel laser cutting subway door, the end door column, the inner layer of the rib plate, and the nesting of the blind window rib plate.

　　Part of the die extrusion parts, due to the high design and manufacturing cost of blanking mold, manufacturing cycle is long, blanking quality is not good and other reasons, need to choose 3d laser nesting, hole processing.
