There are several common errors in machining. Do well and avoid these errors, so that the quality of the processed parts can be improved. The machining accuracy and the machining error are actually a problem. There are only two kinds of opinions. Therefore, the size of the machining error In fact, it also reflects the level of machining accuracy. Enter the text below. What are the main causes of machining errors?
1. The geometric error of the fixture
The role of the fixture is to make the parts equivalent to the tool and the machine tool have an accurate position. Therefore, the geometric error of the fixture has a very large impression of the position error in machining;
2. Adjustment error
In each process of machining, it is always necessary to make different adjustments to the process system. Because the adjustment cannot be absolutely accurate, adjustment errors will occur. In the process system, the mutual position accuracy of the tool and the part on the machine tool It is mainly ensured by adjusting machine tools, fixtures, tools and workpieces. When the original accuracy of machine tools, fixtures, tools, and blank parts meet the process requirements but dynamic factors are not considered, the adjustment error is for the machining error in machining Played a decisive role;
3. Errors caused by thermal deformation of the process system
The thermal deformation of the process system will have a greater impact on the machining errors, especially in the process of precision machining and large-size parts processing, because the machining errors caused by thermal deformation can sometimes account for half of the total part error;
4. Measurement error
When parts are measured during processing or after processing, the measurement method and accuracy of measuring tools, workpiece and subjective and objective factors will directly affect the accuracy of measurement;
The above are several common errors in mechanical processing plants. In the actual production process, pay attention to preventing and avoiding the occurrence of these phenomena, and then the machining accuracy of the parts can be achieved.
