The purpose of mechanical parts processing is to serve the society faster, especially the processing accuracy of parts. As a key component of industrial equipment, the precision of parts affects the quality of machinery. The machining accuracy does not meet the requirements, and it is likely that the parts will not match in the whole process of mechanical assembly. To ensure the success of the whole process of mechanical assembly, it is necessary to improve the machining accuracy of the machine. The improvement of precision can make the machine more smooth when it is put into use in the later period, and the damage between parts will be reduced, thus promoting the machine to have a longer service life. The investment in machinery maintenance of relevant companies will decrease a lot, the productivity of processing plants will be greatly improved, and the economic benefits of the company will be significantly improved. In addition, the improvement of machining accuracy is in line with the requirements of modern society and national development, so it is urgent to improve the machining accuracy.
Precision and error are all the main indicators to evaluate the processing characteristics of mechanical parts. In the production of holes, shafts, etc., tolerance levels need to be strictly implemented. The tolerance grade is also the main reflection of the precision. The higher the precision, the smaller the scale value of the dimensional tolerance. Machining errors are only continuously reduced and cannot be completely eliminated. The precision is obtained by comparing the main parameters of the produced and processed mechanical geometry with the design drawings. The precision includes the surface specification of the machinery, which needs to be compared with the design scheme standard. If it fluctuates within the allowable range of the standard, the precision will reach the specified value; Pattern accuracy, such as axis and parallelism, can reasonably ensure the quality of mechanical pattern by strictly controlling the pattern accuracy; Part accuracy is also obtained by comparing it with the standard plan. Flatness and flatness are all part accuracy.
When processing mechanical parts, it is not only required to operate according to various specifications, but also the specific conditions of production and processing. Make corresponding adjustment within the scope allowed by the specification. The improvement of precision represents the improvement of product cost. When improving the precision, an effective production and processing plan should be established according to the specific conditions of the processing plant, so as to ensure that a larger precision improvement can be achieved with a smaller cost and capital investment. With the development of science and technology, many excellent technical and production equipment have been introduced into the mechanical processing industry in China. The company can also obtain great economic benefits in reducing the production and processing error and reasonably improving the mechanical quality.
