The manufacturing error of the machine tool covers various aspects such as spindle rotation error, guideway error and transmission chain error. Spindle rotary error, that is, the spindle in the actual rotary process, its axis and the average axis of the deviation between, which is directly related to the accuracy of the workpiece processing.

01 Machining Error Analysis Errors in machining have a profound impact on the overall process performance. In order to improve the productivity and quality of mechanical products, we must break through the limitations of machining technology to effectively reduce and control these errors. However
