Summary :In recent years, mechanical processing industry has been developing rapidly in China, the process and level of mechanical processing are continually rising. And proper use of scientific processing and technology during mechanical processing, it can not only guarantee the quality of processed products, but also improve production efficiency, and thus effectively promote the better development of the machinery industry. In view of this, the article carries on the thorough analysis to the mechanical processing, hoping it can provide certain reference and the lessons for the personnel who engaged in the mechanical processing.
Key words: Thinking of machining technology
Machining is a very complicated process, it requires personnel to have good theoretical knowledge and practical skills to complete the assembly and production of the products. Therefore, mechanical processing has high requirements for process technology, it is very important to strengthen the research on technology.
1.Summary of machining technology
In the machinery manufacturing industry, machining processing technology is sort of professional technical that must be used. To improve the processing technology level, it is necessary to train relevant technicians, so that it can be really used for operation,
At the same time, it is necessary to ensure that the corresponding process flow and product quality are completely in line, meet the requirements of the corresponding standard. Usually, in a machine processing enterprise, it is necessary to set up relatively complete process technological departments and technical departments to ensure the proper operation of mechanical processing. The actual functions of the two departments are to understand and analyze the types, models and performance of mechanical equipment, further considering the actual level of technology at the present stage and the level of front-line operators, then formulate corresponding processing technology and technical documents to provide reference and standard for operator's work, at the same time, it provides complete and appropriate technical validation standards for other departments.
In addition, it is influenced by the production plan of company etc. other many factors, mechanical processing and technology should be adjusted and amended accordingly, only in this way can we ensure that the processing technology, processing and processing technology have good pertinence and practicability. If from a technical point of view, the processing technology must be based on a relatively standard and effective process, the use scientific measures and corresponding methods to adjust the appearance, actual location and product properties of the processed products, and to ensure the accuracy of the parameters of the product, thus better improve the quality of mechanical products.
2. Effective function of machining technology in machining process
2.1 It can guarantee the good operation of the mechanical equipment
As everyone knows，A mechanical equipment is made up of many mechanism, such as transmission system, power system, etc.. Therefore, only ensure all mechanisms of the mechanical equipment perform well and function well, then can it fully display its functions in the actual construction process, further to meet the actual needs. During the process of mechanical processing, if we cannot effectively ensure the actual processing flow is good and manages it scientifically; otherwise it will cause certain safety hazards to the operation of machinery and equipment. With the improvement of science and technology, many processing technologies and technologies need to rely on computer systems for auxiliary operation. The application of modern information technology can effectively feedback the situation during the operation of machinery, even if a fault occurs, the system will feed the information to the central integrated system, then, the relevant maintenance personnel can be dispatched for the first time to eliminate faults and hidden dangers. Therefore, good machining technology can ensure the safety and reliability of machinery operation, and then improve the level of enterprise safety production.
2.2 can effectively meet production efficiency
At this stage, social development has increased the actual demand for machinery and equipment and in the mechanical level and mechanical accuracy etc, have been improved certainly. Under this background, the requirements for processing technology and processing technology are also promoted, in another word, processing technology and manufacturing technology must be consistent with mechanical processing. Product quality is achieved through good application of technology and process; therefore, enterprise must pay attention to it. At the same time, based on the previous technology, modern machining technology and process technology have completed through continuous research, study, and summary and practice operation; it also pays an effective respect for the actual requirement of the machinery manufacturing industry, then builds up and meets the requirements of manufacturing industry for mechanical accuracy.
2.3 Good technology achieves low consumption and high productivity.
In recent years, energy saving and emission reduction have been advocated in China, therefore, the past high energy consumption and low productivity machining process and technology have been unable to meet the actual needs of social development. And facing the continuous improvement and perfection of machining technology and level, it makes the machining not only meet the actual needs of the development of agriculture and industry, the goal of energy saving and emission reduction has been gradually reached, at the same time, it also effectively optimized and configured the equipment performance, and improved the production capacity.
3 An effective way to improve machining precision
3.1 Error reduction method
During the process of mechanical processing, use error reduction to improve the accuracy of mechanical products, it is a more common process and technology. This method is usually applied before machining, means before the product is processed, it requires that the corresponding engineers to check and Proofread the design plan, process flow, then use scientific measures to summarize the potential problems that may affect the machining accuracy, and organize the internal departments responsible for discussion, such as the technology department, the technology department, the design department, the production department etc., and then take the most appropriate methods and measures to solve them, to eliminate or reduce error as far as possible, thus ensuring machining quality and accuracy. For example, in the processing of long shaft parts, due to higher processing precision, and the shaft will also be affected by its own, external forces and machine tool stability during the machining process, therefore, there may be some errors in the machining process. Therefore, before processing, operators must carefully check the design drawings, and then choose a reasonable cutting method, and use lathe center to fix it, ensure that it will not shake during machine tool running, and further to affect the cutting performance. At the same time, during the processing, we should use coolant to avoid the overheating distortion of the shaft, at the same time; it can reduce the wear of mechanical equipment.
3.2 error compensation
All machining processes are more or less affected by human factors, which cause the certain deviation between the processing parameters and drawings and process design, and this part of the error is often not easy to detect, therefore, it is necessary to solve the problem before processing, so that avoid unqualified products or waste material, more over later it could impact on product manufacturing and assembly seriously. At present, our country mainly uses the way of error compensation to reduce the impact on mechanical products. This method can not only compensate for the errors existing in the previous process, it can also reduce the errors in machining process and effectively improve machining accuracy.
4 Future development direction of machining technology
With the improvement of the development level of the machinery manufacturing industry, the manufacturing industry is also facing new challenges and problems. Therefore, if we want to the products processed by our enterprises to have a place in the market, we must improve the technology and process of manufacturing, effectively improve the actual quality of mechanical products, improve the performance, reliability and durability of the product, and finally increase the operation level and life span of mechanical products. At the same time, we should try to find the market position as much as possible, improve the level of product design and expand the scope of the market. Only in this way can we better promote the development of mechanical processing toward integration, and effectively promote the level of mechanical processing industry, and better serve the development of society.
