Machining accuracy is one of the key factors in mechanical manufacturing, which directly affects the performance, quality and stability of the product. Ensuring the machining accuracy is not only conducive to improving production efficiency, but also can reduce production costs and lower the scrap rate. This article will explore from two aspects: the factors affecting the machining accuracy and the safeguard measures.

There are many factors that affect accuracy in the machining process. For instance, the precision of machine tools, the wear of cutting tools, the selection of process parameters, and the technical proficiency of the operators, etc. Among them, the accuracy of the machine tool is the foundation. If the accuracy of the machine tool is insufficient, the processing accuracy cannot be guaranteed. Meanwhile, the wear of the cutting tool will also affect the cutting force and cutting temperature, thereby influencing the machining accuracy. In addition, the selection of process parameters and the skill level of operators also have a significant impact on processing accuracy.

To ensure the machining accuracy, a series of measures need to be taken. Firstly, the accuracy of the machine tool should be enhanced, including the accuracy of the spindle, the feed system and the bed, etc. Secondly, appropriate tools and cutting parameters should be selected. According to different workpiece materials and processing requirements, choosing suitable tool materials and cutting parameters can effectively improve the processing accuracy. In addition, optimizing the processing technology is also an important means to ensure accuracy, including formulating reasonable process flows, choosing appropriate clamping methods and coolants, etc. Then, formulating strict operation norms and strengthening the skills training of employees are also effective measures to ensure the machining accuracy.

The following is an example of ensuring machining accuracy. In a certain mechanical manufacturing company, in order to improve the processing accuracy, the following measures were taken: Firstly, detailed inspection and maintenance of the machine tools were carried out, which improved the accuracy of the machine tools; Secondly, tool materials with high hardness and high wear resistance were selected, and the cutting parameters were optimized at the same time. In addition, more stringent technological processes and operation norms have been formulated, and rigorous skills training has been provided to the employees. The implementation of these measures has significantly improved the processing accuracy of the company, while reducing the scrap rate and production costs.

In conclusion, ensuring machining accuracy is of vital importance for small-batch processing. In order to improve processing accuracy, it is necessary to comprehensively consider factors such as machine tools, cutting tools, processes and operations, and take corresponding measures.
