New technology pushes the machine tool industry to high-end
Pleated screens have emerged as a popular choice for homeowners seeking a sleek and functional solution for their windows and doors. These screens are designed with a unique pleated fabric that allows for smooth and effortless operation. With their accordion-like folding mechanism, pleated screens can be easily opened or closed, providing convenient access to the outdoors while effectively keeping insects and debris at bay. The pleated design also offers enhanced visibility and airflow, allowing for unobstructed views and optimal ventilation. Whether you're looking to enjoy a bug-free breeze or simply want to add a stylish touch to your living space, pleated screens offer a practical and aesthetically pleasing option.

China's machine tool industry's total industrial output value has jumped from the third place in the world to the first place, becoming the world's largest machine tool producer. According to statistics, since 2010, the growth rate of production and sales of China's machine tool industry has been above 40%. It is expected that the compound growth rate of the machine tool industry will be 25% to 30% in the next five years.
The continuous growth of domestic consumer demand has opened up a broad market for machine tool manufacturing, providing opportunities for development, but at the same time it has also raised challenges. The number of manufacturing units in China is extremely large. Although the advantages are obvious, the weaknesses are also prominent, and the machine tool industry is even more important. At present, the technical level of China's machine tool industry is mostly in the middle and low-end. The "12th Five-Year Plan" requires that the machine tool industry must develop at a high level, and use technological innovation as a means to enhance the level of management innovation and move toward modernization and high-end.
In the machine tool industry, the development of welding technology has been developed with the application of welding structure of machine tool products. Metal cutting machine tools, forging machinery and casting machinery products are the main fields of welding technology application in the machine tool industry. Welding technology has also gradually developed into the leading technology in the machine tool industry, which is mainly reflected in the following aspects:
Some key enterprises have established welding workshops or metal structure factories with a certain scale, and established a complete welding management system, and absorbed the welding process standards of imported products.
The welding process has been perfected, from a single processing technology to a complete set of emerging comprehensive engineering technologies from raw material pretreatment, cutting blanking, forming, welding, post-weld inspection and post-weld treatment.
CNC precision cutting and computer programming nesting technology has been applied.
Advanced and efficient new processes such as CO2 gas and argon-rich gas shielded or submerged arc welding have been promoted.
X-ray inspection and ultrasonic non-destructive inspection are widely used to stabilize the intrinsic quality of the weld.
The new vibration aging process has been promoted to achieve the purpose of reducing and homogenizing the residual stress of the welded structure, reducing the deformation of the welded parts and stabilizing the accuracy.
At present, the main welding techniques applied in the machine tool industry have the following aspects: application of steel plate pretreatment technology; application of numerical control cutting technology; application of high efficiency welding technology such as gas shielded welding: at present, high efficiency welding technology such as gas shielded welding, It has been widely used in machine bed, gear, eccentric body, rocker shaft, cylinder block, pipe flange and casing which are not processed after welding. It has become one of the main processes of welding in the machine tool industry; vibration aging technology application Application of welding automation and mechanization technology: In addition to CO2 semi-automatic welding, the welding automation of machine tool industry is mainly embodied in the application of submerged arc automatic welding, mainly used in the welding of steel plates and the barrel welding of pressure vessels; propane energy-saving and environmental protection Application of cutting gas; application of non-destructive testing technology.
With the increasing application of welding structures for machine tools, welding by casting, welding by forging, and welding by cutting have become the general development trend of machine tool manufacturing, and machine tool manufacturing is inseparable from welding. At present, the welding technology of the machine tool industry is also developing in an efficient and automatic direction.
Although the numerical control rate of the output of China's machine tool industry has increased, the overall numerical control rate is still lower. Compared with the level of 70% in developed countries, there is still room for improvement. I believe that with the intensity of China's "structural structure" Constantly increasing, the numerical control rate of machine tools in China will be significantly improved. It is also imperative to strengthen the management capabilities of the majority of machine tool enterprises and accelerate the process of informationization.
"Cloud computing" is the hottest word in recent years. All walks of life are trying to find a way to move closer to it. The machine tool industry is no exception. Using cloud computing companies can save costs and easily realize data and application sharing between different devices. Compared with traditional application platforms, cloud computing platforms have the advantages of powerful computing power, storage capacity, diverse services, and high cost performance. Nowadays, cloud computing has been accepted by most enterprises, and cloud applications have begun to spread at home and abroad. As an important industry in China, machine tool enterprises can only be invincible if they dare to break the traditional constraints, be brave in innovation, and be willing to try. .
