In 2013, just half passed. From the perspective of the development of the past six months, China's laser cutting equipment continues to rise, and all major economic indicators have also picked up. The laser cutting machine industry is still in a period of rapid development, and laser equipment has become an advantage. In the industry, local governments have also begun to pay attention to the investment in this industry. Some laser companies that were once at a disadvantage have begun to cheer up and made great progress.
In recent years, with the continuous improvement of the domestic economic situation, China's laser industry has achieved rapid development, and the government has always attached great importance to the development of this industry. Laser cutting machine equipment is an indispensable tool in China's metal processing industry and key industrial fields. At present, laser cutting machine manufacturers want to create a different market in the future laser cutting machine industry, then we must achieve independent production, can not rely on foreign accessories, and all accessories must be automated equipment, the only way to better possession market.
Laser cutting machine is widely used in all walks of life CNC laser cutting machine is widely used in many fields, such as the automotive industry, shipbuilding industry, power generation equipment, aerospace, military equipment. With the rapid development of science and technology, in order to improve product accuracy and efficiency, the requirements for CNC cutting machines have gradually increased. The following are the processing requirements for CNC laser cutting machines in various industries.
CNC laser cutting machine is widely used in all walks of life because its high efficiency and high precision can meet the increasingly advanced processing requirements of all walks of life. With the rapid development of science and technology, the processing requirements of the future machinery industry will be even higher. In order to meet the continuously improving processing requirements of CNC cutting performance, various industries put forward the following requirements for CNC laser cutting machines:
The automotive engine head and body stamping parts production line is characterized by continuous, high-efficiency and high reliability. The automotive industry requires special research on the technical features of auto parts and mutual exchanges with the automotive industry to jointly develop complete sets of flexible production with modularization and serialization. line. The flexible production line is based on the machining of engine parts such as engine heads, cylinder heads, crankshafts, connecting rods, camshafts, and boxes. The rapid assembly of modules that can adapt to mixed outflows can be reorganized into production lines to grasp the performance evaluation, error tracing, Quality control and management integration technology, development of high-speed precision, reliable CNC cutting machine, at the same time with high-speed materials, auxiliary equipment such as deburring function.
The large-sized ship's hub processing parts are concentrated on the bases, frames, cylinder blocks, cylinder heads, piston rods, crossheads, connecting rods, and crankshafts of high-power diesel engines, as well as transmission shafts, rudder shafts, and thrusters of the reduction gears, etc. The material of the material is special alloy steel, which is generally a small batch of processing, and the required processing yield is 100. The hinged workpiece has the characteristics of large weight, complex shape, high precision, and difficult processing. The processing of large-scale ship pivots requires heavy-duty, super heavy-duty CNC cutting machines with high power, high reliability, and multi-axis.
Power-generating equipment hub processing parts are heavy, special shape, high precision, difficult to process, and expensive, such as a single nuclear power plant pressure vessel weighing 400 to 500 tons, a large steam turbine and generator rotor weight exceeds one hundred tons, requiring reliable Work for more than 30 years. Therefore, the characteristics of the CNC cutting machine required for the manufacturing of the power equipment hub parts are large specifications, high rigidity, and high reliability.
The structural characteristics of the typical parts of the aviation industry are a large number of overall thin-walled structures with complex shapes. In order to increase aircraft maneuverability, increase payloads and voyages, reduce costs, carry out lightweight design and widely adopt new lightweight materials. A large number of aluminum alloys, high-temperature alloys, titanium alloys, high-strength steels, composite materials, and engineering ceramics are now widely used. The complicated structure of thin-walled parts and honeycomb pieces is complex in shape, with many holes, cavities, grooves, ribs, and the like, and the process rigidity is poor. According to the structural features and processing requirements of the machining parts of the aviation industry, the CNC cutting machine is required to have sufficient rigidity, simple operation, clear man-machine interface, spline interpolation, and process average control, so as to reduce the impact on the machining accuracy at the corners.

Comparison of fiber laser cutting machines and traditional high-power laser cutting machines The fiber laser cutting technology only appeared in the last 3 to 5 years. Although many companies are just beginning to understand this technology, they are beginning to realize the difference between fiber laser cutting and common CO2 laser cutting. With the continuous improvement of cutting technology, fiber laser cutting has become one of the most advanced technologies in the industry.
Thermal energy cutting methods mainly include flame, plasma and laser cutting techniques, in which laser cutting can achieve the best cutting quality, especially for fine features and hole cutting with a diameter and thickness ratio of less than 1:1. As a result, laser cutting technology has become the most suitable method in the industry for requiring strict fine cutting.
In the field of laser cutting, fiber laser cutting gains much attention because it provides both the speed and cutting quality that CO2 laser cutting can achieve, and the maintenance and operating costs are significantly reduced. So this makes the prospect of fiber laser cutting good, and many experts believe it will quickly replace other laser cutting systems.
The main advantages of fiber cutting In carbon dioxide laser cutting, carbon dioxide gas is the medium that generates the laser beam. However, fiber lasers work via diodes and fiber optic cables. The fiber laser system pumps the laser beam through multiple diodes and then transmits it through a flexible fiber optic cable to the laser cutting head rather than through the mirror. This has many advantages. The first is the size of the cutting bed. In gas laser technology, mirrors must be set within a certain distance, which is different from that of fiber laser technology. It is even possible to install the fiber laser next to the plasma cutting head of the plasma cutting bed. The CO2 laser cutting technology does not have such an option. Also, the ability of the fiber to bend makes the system more compact when compared to an equivalent power gas cutting system.
The most important and significant advantage of fiber cutting technology is its energy efficiency. With fiber laser complete solid-state digital modules and a single design, fiber laser cutting systems have higher electro-optical conversion efficiency than carbon dioxide laser cutting. For each power supply unit of the CO2 cutting system, the actual general utilization is about 8 to 10. And for the fiber laser cutting system, the user can expect higher power efficiency, about 25 to 30. In other words, the overall energy consumption of an optical fiber cutting system is about 3 to 5 times less than that of a CO 2 cutting system, making the energy efficiency increase to more than 86.
Fiber lasers have short-wavelength characteristics, which increase the absorption of the light beam by the cutting material and enable cutting of materials such as brass and copper as well as non-conductive materials. The more focused beam produces less focus and deeper focal depth, so fiber lasers can quickly cut thinner materials and cut medium thickness materials more efficiently. When cutting materials as thick as 6mm, the cutting speed of the 1.5kW fiber laser cutting system is equivalent to the cutting speed of the 3kW CO2 laser cutting system. Since the operating costs of fiber-cutting are lower than those of ordinary carbon dioxide-cutting systems, this can be understood as an increase in output and a reduction in commercial costs.
There is also the problem of maintenance. Carbon dioxide gas laser systems require regular maintenance; mirrors need to be maintained and calibrated, and resonant cavities require regular maintenance. On the other hand, fiber laser cutting solutions require almost no maintenance. The carbon dioxide laser cutting system requires carbon dioxide as the laser gas. Due to the purity of the carbon dioxide gas, the inside of the resonant cavity may be contaminated and needs to be cleaned regularly. For a multi-kilowatt CO2 system, this will cost at least US$20,000 per year. In addition, many carbon dioxide cuts require high-speed axial turbines to deliver the laser gas, and turbines require maintenance and refurbishment. Finally, compared to carbon dioxide cutting systems, fiber cutting solutions are more compact and have less impact on the earth, so they require less cooling, and energy consumption is significantly reduced.
The combination of less maintenance and higher energy efficiency makes fiber laser cutting less carbon dioxide emissions than carbon dioxide laser cutting systems and is more environmentally friendly.
