Nowadays, with the continuous development of society, people's living standards have improved significantly, and we often come into contact with mechanical parts processing around us, and its arrival has brought great convenience to our lives. Sometimes, due to our use of improper methods, mechanical parts processing is prone to errors, when we should do it? Today, I came to learn with you to learn what errors are prone to mechanical parts processing, respectively, as follows.
1, positioning error: positioning error mainly includes the benchmark does not overlap error and positioning vice manufacturing inaccuracy error.
2, measurement error: parts in processing or measurement after processing, due to measurement methods, gauge accuracy and workpiece and objective factors have a direct impact on the measurement accuracy.
3, tool error: any tool in the cutting process is inevitable to produce wear, and thus cause the size and shape of the workpiece to change.
4, fixture error: the role of the fixture is to make the workpiece equivalent to the tool and machine tool has the correct position, so the geometric error of the fixture on the machining error (especially the position error) has a great impact
5, the machine tool error: including spindle rotation error, guide error and drive chain error. Spindle rotation error refers to the actual axis of rotation of the spindle moment relative to its average axis of rotation of the amount of change, it will directly affect the accuracy of the workpiece being machined.
