The characteristics and development prospect of optical fiber laser cutting machine

The characteristics and development prospect of optical fiber laser cutting machine. Fiber laser is the development of a new type of fiber laser output in the world of high energy density laser beam, and gathered in the workpiece surface, the workpieces is super fine focus light irradiation area moment melting and gasification, move the light to shine through numerical control mechanical system and automatic cutting. Compared with huge gas laser and solid state laser has obvious advantages, has gradually developed into a high precision laser machining, laser radar system, important candidates in the field of space technology, laser medicine and so on. Optical fiber laser cutting machine it can do is cut, also can do the bevel cutting processing, and edge neat, smooth, suitable for cutting metal plate and so on high precision processing, at the same time combined with mechanical arm can be three-dimensional cutting instead of the original import five-axis laser. Than the average carbon dioxide laser cutting machine more save space and gas consumption, photoelectric conversion rate is high, is the new products of energy conservation and environmental protection. The cutting edge: 1, high cutting precision, laser cutting machine positioning accuracy is 0. 5 mm, repeat positioning accuracy is 0. 03mm。 2, narrow kerf width laser cutting machine, laser beam focus into very small points of light, make the focus to achieve high power density, degree of material quickly heated to gasification, evaporation form holes. Along with the relative linear beam and mobile, make continuous forming holes cutting seam width is very narrow, notch width is commonly 0. 10 - 0. 20mm。 3, laser cutting machine cut surface is smooth, no burr, cutting, surface roughness of general control in the Ra6. 5 or less. 4, laser cutting machine speed, cutting speed can be up to 10 m/min large positioning speed can be up to 30 m/min a lot faster than the speed of the cutting. 5, good quality of laser cutting machine for cutting: non-contact cutting, cutting heat effect is very small, almost no thermal deformation of workpiece, completely avoid material formed when punching and shearing edge collapse, generally do not need secondary processing kerf width. 6, don't damage the workpiece: laser cutting head surface in contact with materials, ensure no scratch artifacts. In July and is not affected by the shape of the workpiece, laser processing flexibility, can be processing any graphics, can cut pipes and other profiles. 8, laser cutting machine can be cut to a variety of materials processing, such as plastic, wood, PVC leather, textile, organic glass, etc. 9, saving investment, laser processing without mould, no mould cost, do not need to repair the mould, mould replacement time saving, so as to save the processing cost, reduce the production cost, especially for large products processing. 10, saving material: using a computer programming, can cut different shapes of products, to improve the utilization rate of material. 11, increase the speed of the sample factory: product drawings, after the formation of laser processing can be done, immediately object of a short period of time to get the new product. 12, security, environmental protection, laser processing waste less, low noise, clean, safe, pollution-free, greatly improved the working environment. Its main features: a, fiber laser electrical and optical conversion efficiency is high, the conversion efficiency of 30% above, don't need to match the cold water machine, small power fiber laser using air cooling, can greatly save electricity at work, saves the operation cost, high production efficiency. Two, laser runtime only need electricity, do not need to generate additional gas laser, has low operation and maintenance costs. Three, fiber laser using semiconductor modular and redundancy design, inside the cavity no optical lenses, do not need to start time, with free adjustment, free maintenance, high stability, the advantages of reducing the costs of accessories and maintenance time, this is a traditional laser incomparable four, the output of the fiber laser wavelength of 1. 064 microns, is 1/10 of the wavelength, CO2 output beam quality is good, high power density, is very beneficial to the absorption of metal material, has excellent ability of cutting, welding, so that the processing of low cost. Five, routing optical fiber transmission light, does not need complex reflector light system, such as light path is simple, stable structure, light path and maintenance-free. Protect the lens is contained in six, cutting head, the focus lens and other precious few consumption of consumption goods. Seven, the light through the optical fiber export, makes the design of the mechanical system is very simple, very easy with a robot or multi-dimensional workbench integration. Eight, fiber laser is small in size, light weight, portable work position, cover an area of an area small. After nine, laser and light brake can be more than a machine machine, through the optical fiber spectroscopic, divided into multiple more than one job at the same time, easy to expand functions, convenient upgrade and simple. Its application in the industry: used in sheet metal processing, aviation, aerospace, electronics, electrical appliances, tube fittings, automobile, food machinery, textile machinery, engineering machinery, precision parts, ships, metallurgical equipment, elevators, household appliances, craft gifts, tool processing, decoration, advertising, metal foreign machining, kitchen utensils and appliances, and other manufacturing industries. The processing advantages: ( 1) High precision, fast speed, narrow kerf width, small heat affected zone, the cutting face smooth without burr. ( 2) Laser cutting head not with material surface contact, don't cut the workpiece. ( 3) Narrow kerf width, small heat affected zone, local deformation of workpiece, no mechanical deformation. ( 4) Processing good flexible, can be processing any graphics, can cut pipes and other profiles. ( 5) Steel plate, stainless steel, aluminum alloy plate, can be for any hardness materials such as cemented carbide cutting without deformation.
