01 Error and accuracy of the “twin faces” of the smaller the machining error, the higher the degree of compliance, the higher the machining accuracy. Both actually describe the same thing - just a different perspective. In other words, the size of the error directly determines whether the part can meet the standard!

Machining error is the degree of deviation between the actual geometric parameters (geometric dimensions, geometric shape and mutual position) and the ideal geometric parameters of a machined part.

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.
