Mechanical spare parts processing What kind of problems will arise in the processing of mechanical spare parts?

For experienced processing masters, no matter what the processing is, there will always be some minor problems, but what problems often occur! The machining of mechanical parts is the same, so what happens in the process of machining?

1. Positioning error: Positioning error mainly includes datum misalignment error and positioning pair manufacturing inaccuracy error.

2. Measurement error: When measuring parts during processing or after processing, the measurement accuracy is directly affected by the measurement method, the accuracy of the measuring tool, the workpiece, and the subjective and objective factors.

3. Tool error: Any tool will inevitably be worn during the cutting process, and this will cause the size and shape of the workpiece to change.

4. Fixture error: The function of the fixture is to make the workpiece equivalent to the tool and the machine tool have the correct position, so the geometric error of the fixture has a great influence on the machining error (especially the position error).

5. Machine tool error: including spindle rotation error, guide rail error and transmission chain error. Spindle rotation error refers to the variation of the actual rotation axis of the spindle relative to its average rotation axis at each moment, which will directly affect the accuracy of the processed workpiece.
