mechanical processing technology is a systematic product operation process. in the whole process of the process, various factors such as equipment and personnel have a direct relationship with the quality of product production and operation, thus directly affecting the quality of processing technology. in the processing of auto parts, the geometric error of the processing technology system has a great influence on its accuracy. the geometric error is mainly due to the direct connection between the guide rail and the traditional system and feed accuracy caused by the rotation of the machine tool spindle.
in the process of auto parts processing, the machine tool spindle is the main source of its processing power. through the rotation of the spindle, the relative position of the tool and the processed part is controlled, and it also has a direct impact on the flatness of the surface processing of the parts. during the machining process, if there is an error in the rotation of the spindle, it may cause the rotation line of the spindle to deviate from the set standard central axis, which directly leads to a large error in the processing of the parts. in addition, in the processing of parts, the standard degree of shaft assembly also affects the rotation accuracy of the spindle. if the shaft transfer does not meet the requirements, or the daily maintenance is not in place, resulting in insufficient lubrication of the spindle, the spindle rotation error will also be enlarged.
in the processing of auto parts, the guide rail of the machine tool is mainly responsible for the position movement of the parts, ensuring that the parts are always on the track during the movement, so as to ensure the accuracy of the cutting, advancing and retreating operations of the tool. in the long-term operation of the guide rail of the machine tool, there will inevitably be wear and tear, which will cause the occurrence of guide rail errors, and as the degree of wear increases, the error will also increase. therefore, in machining, the guide rail wear error is also one of the important reasons affecting the accuracy of auto parts. in the transmission system of the machine tool, the error generated during the relative movement of the original parts in the transmission chain will also affect the accuracy of the parts.
in the processing system of auto parts, the precision of the machining tool also directly affects the precision of the parts, and in the processing of some special parts, the precision of the tool plays a decisive role and is the main influencing factor. the function of the tool is to cut the parts. in this process, there will be strong friction between the production parts and the tool, which will cause the wear of the tool to increase with the frequency of use. when the degree of tool wear reaches a certain level, the cutting surface of the parts will be rough, which will affect its accuracy.
