Analysis of Modern Machinery Manufacturing Process and Precision Machining Technology

At present, the rapid development of society and economy puts forward higher requirements on modern machinery manufacturing. In the past, traditional mechanical manufacturing processes have been unable to meet new demands. This requires the active introduction of modern machinery manufacturing processes and Precision Machining technologies to promote the machinery manufacturing industry. Rapid and steady development.

1, modern machinery manufacturing process

(1) Gas shielded welding process. The gas shielded welding process is a welding process using an arc as a heat source and a gas as the protective medium of the object to be welded. During the welding process, the gas will use its own function to form a strong protective layer around the arc, which can play the role of the molten pool and divide the arc and air, thereby reducing the harmfulness of harmful gases that may cause welding. In addition, the arc can be stabilized and fully burned. More typical of carbon dioxide welding and so on.

(2) Stud welding process. The stud welding process is to ensure that one end of the stud touches the surface of the pipe or plate until the contact surface is melted and the stud pressure is increased to complete the weld. The main welding methods include pull arc type and energy storage type. Both are single-sided welding, in which the arc-type is mostly used for heavy industrial welding, and the energy storage type is mostly used for thin-plate welding. The welding process does not cause leakage of water, etc. during use, and is therefore widely used.

(3) Friction stir welding welding process. The friction stir welding process was first applied to many machinery manufacturing industries such as vehicle manufacturing, aircraft manufacturing, and railway manufacturing, and its application scope has been continuously increasing along with economic development. At present, China's friction stir welding process has been very mature, and it will only produce less consumable materials in the welding process, which has great practicality. And in the process of welding the aluminum alloy, it can directly weld the weld seam of 800m, and the welding temperature is also low.

(4) resistance welding process. In the resistance welding process, an object to be welded is placed between the positive and negative electrodes and is energized to melt the current by contacting the surface of the object to be welded and the resistive thermal effect generated near the surface of the object to promote fusion with the metal. Resistance welding process has many advantages, such as high production efficiency, high degree of mechanization, high welding quality, short heating time, and so on, so it is widely used in aerospace, automotive, home appliances and other modern machinery manufacturing.

(5) Submerged arc welding process. The submerged-arc welding process refers to the welding of arcs under the flux layer for automatic and semi-automatic separation. Automatic submerged arc welding is often used only for welding, while welding wire and moving arcs require specialized trolleys for transport. However, in the semi-automatic submerged arc welding, welding wire and moving arc often need to be manually transported, and therefore almost eliminated in the development process. In addition, the use of submerged arc welding process, should pay special attention to the choice of flux, alkalinity, etc. can best reflect the performance of the welding process, metallurgical performance, current level of important technical standards.

2, precision machining technology

(1) Precision cutting technology. Normally, precision cutting technology uses direct cutting to obtain high precision, so better products are required for cutting. For example, it must meet the requirements of high-precision surface roughness. However, it is worth noting that if you want to use cutting methods to obtain high-precision and high-level surface roughness, you should actively eliminate the influence of factors such as machine tools, tools, workpieces and the outside world. For example, in order to continuously improve the machining accuracy and accuracy of the machine tool, it is necessary to select a machine tool with higher rigidity, smaller thermal deformation, and good vibration resistance.

(2) Ultra-precision grinding technology. For processing and its surface roughness up to 1 ~ 2mm, and the use of atomic level grinding and polishing silicon. In the past, traditional processing methods such as grinding, grinding, polishing, etc. were unable to meet the needs of the work. Therefore, we must in-depth analysis and study of new principles and new methods. It is in this context of development that ultra-precision grinding technology has emerged and is playing an increasingly important role in mechanical precision mechanics.

3, technical characteristics

(1) The relevance of modern machinery manufacturing processes and precision machining technologies. As far as manufacturing technology is concerned, modern machinery manufacturing processes and precision machining technologies involve many aspects of the machinery industry, such as manufacturing engineering, product design and development, product process design, processing and manufacturing, and product sales. Once these problems occur, Will directly affect the entire project chain. Therefore, we must attach great importance to the correlation between modern machinery manufacturing and precision machining technology, so as to truly promote the progress and development of mechanical technology. Therefore, in the specific practice, we must fully integrate modern machinery technology and precision machining technology to promote the progress of machinery and realize the rapid development and progress of technology.

(2) The systematic nature of modern machinery manufacturing processes and precision machining technologies. Modern machinery manufacturing and production is a relatively complicated system engineering. In the process of modern machinery manufacturing processes and precision machining technologies, such as product design, production, and sales, computer information technology, modern sensing technology, and production are involved. Many technologies such as automation technology. In addition, it may be necessary to apply new processes, new materials, new management methods, etc. Therefore, on the whole, the manufacturing technology of the machinery industry is inseparable from the comprehensive application of a variety of modern advanced technology, which makes the modern machinery manufacturing process and precision machining technology have a larger system.

(3) The globalization of modern machinery manufacturing processes and precision machining technologies. At present, with the development of economic globalization, many of our country’s economic fields have gradually achieved convergence with the international community. The trend of economic globalization has developed an important trend in the current social development of the siege city. At the same time, under the background of economic globalization, the market competition among countries has intensified. To increase the competitiveness of enterprises in domestic and international markets, China’s machinery manufacturing industry must keep pace with the pace of development of the times and actively introduce international advanced machinery manufacturing processes and precision machining technologies. We will increase investment in scientific research within the company, cultivate senior technical personnel, and research and develop machinery manufacturing processes and precision machining technologies that meet the actual conditions of the company, so as to realize the healthy and sustainable development of the machinery manufacturing enterprises.

4 Conclusion

The modern machinery manufacturing process and precision machining technology are the core factors that strongly promote the rapid and steady development of the machinery manufacturing industry, and require our high attention. Under the background of economic globalization, in order to promote the broader development space for the machinery manufacturing industry, it is necessary to continuously introduce, improve, and develop new modern machinery manufacturing processes and precision machining technologies, and apply them to the machinery manufacturing industry. In order to better serve the development of modern machinery manufacturing and processing, and further contribute to the sound development of China's manufacturing technology in the international technology market.
