Analysis of domestic laser cutting machine equipment market demand in 2014

Release time: 2014.10.25 News source: Laser cutting machine, laser engraving machine, laser marking machine, laser equipment brand manufacturer-Dongguan Heli Laser Equipment Co., Ltd. Browse times:
The laser cutting machine uses a focused high power density laser beam to irradiate the workpiece, so that the irradiated material is rapidly melted, vaporized, ablated or reaches the ignition point, and at the same time, the molten material is blown out by means of a high-speed airflow coaxial with the beam, thereby realizing the workpiece Cut it apart. Laser cutting is one of the thermal cutting methods.
Compared with other thermal cutting methods, laser cutting has the general characteristics of fast cutting speed and high quality. It is summarized as follows.
Good cutting quality: Due to the small laser spot, high energy density, and fast cutting speed, laser cutting can achieve better cutting quality. ① The laser cutting incision is narrow, the two sides of the slit are parallel and perpendicular to the surface, and the dimensional accuracy of the cutting part can reach ± 0.05mm. ② The cutting surface is smooth and beautiful, and the surface roughness is only a few tens of micrometers. Even laser cutting can be used as the last process, without mechanical processing, and parts can be used directly. ③ After laser cutting, the width of the heat-affected zone is small, the performance of the material near the slit is almost unaffected, and the deformation of the workpiece is small, the cutting accuracy is high, the geometry of the slit is good, and the cross-sectional shape of the slit is more regular. Rectangle. The comparison of laser cutting, oxyacetylene cutting and plasma cutting methods is shown in Table 1. The cutting material is a 6.2mm thick low carbon steel plate.
High cutting efficiency: Due to the transmission characteristics of lasers , laser cutting machines are generally equipped with multiple CNC tables, and the entire cutting process can be fully CNC controlled. During operation, just changing the NC program can be used to cut parts of different shapes, both 2D and 3D.
Fast cutting speed: Cutting a 2mm thick low carbon steel plate with a power of 1200W, the cutting speed can reach 600cm / min; cutting a 5mm thick polypropylene resin plate, the cutting speed can reach 1200cm / min. The material does not need to be clamped and fixed during laser cutting, which can save tooling fixtures and save the auxiliary time of loading and unloading.
Non-contact cutting: The cutting torch has no contact with the workpiece during laser cutting, and there is no tool wear. When processing different shapes of parts, there is no need to change the "tool", only the output parameters of the laser need to be changed. The laser cutting process has low noise, low vibration and no pollution.
There are many types of cutting materials: Compared with oxyacetylene cutting and plasma cutting, there are many types of laser cutting materials, including metal, non-metal, metal-based and non-metal-based composite materials, leather, wood and fibers. However, for different materials, due to their different thermophysical properties and laser absorptivity, they show different laser cutting adaptability.
Laser cutting machine equipment classification introduction There are currently three types of laser cutting equipment on the market, YAG laser cutting machine , CO2 laser cutting machine , fiber laser cutting machine :
1. YAG laser cutting machine . This laser cutting equipment has the characteristics of low price and good stability, and is mainly used for punching, spot welding and cutting of thin plates. Low energy efficiency, current output power is below 600W, non-metallic materials cannot be cut, and maintenance costs are high. 2. CO2 laser cutting equipment. It can cut thicker metal sheet materials, and it also has a good cutting effect on non-metallic materials. However, the photoelectric conversion efficiency is low, the equipment is huge, and the maintenance cost is high.
3. Fiber laser cutting machine . Through optical fiber transmission, it has a high degree of flexibility, high speed, few failure points, low maintenance costs, convenient maintenance, and high photoelectric conversion rate. It has a great cost-effective advantage in supporting the system. It is mainly used to cut metal sheets within 20mm. The laser beam is not easily absorbed by the highly reflective material, and the cutting effect on the highly reflective material is not very satisfactory. It cannot cut and process non-metallic materials.
Han's laser cutting equipment business grows Cutting equipment field: realized sales income of RMB 471.144 million, a year-on-year increase of 29.08%, and its market share has continued to increase.
It is understood that the Han's laser 3D 5-axis laser cutting machine has been upgraded and mass-produced. The automation and intelligent equipment have gained market recognition. The laser cutting flexible production line has been successfully customized for customers, consolidating the development of high-power laser equipment system integration and personalized custom development business development. basis. The cumulative sales of fiber laser cutting machines exceeded 1,000, and the production and sales volume ranked first in the world. With the continuous popularization of industrial applications, the demand for laser cutting equipment will become wider and wider.
Concluding remarks Dahan Laser Zuo Yan believes that in the next few years, with the implementation of favorable national policies and the improvement of the industry's technical level, China's laser cutting machine industry will definitely have a greater development. The combination of laser technology and many emerging disciplines has improved the independent innovation capability of the laser cutting machine industry, adapted to the trend of globalization, and formed a new economic growth point.
The state's macro-control policies on fixed asset investment may also have a direct impact on the demand for industry products. With the development of the laser cutting machine industry and the enhancement of technology maturity, it is also difficult to rule out the possibility that the market share of laser cutting machine manufacturers will decrease and the price of products will decrease due to factors such as increased competitors and enhanced competitors. Therefore, if the industry sales and profit levels are affected by the above factors, there may be a certain degree of fluctuation. But in general, China's laser cutting equipment market in 2014 has huge demand and considerable profits.
