There are many factors that affect the machining accuracy. In addition to the geometric accuracy of the machine tool itself and the environment in which it is processed, it is also affected by the following factors:

Spindle thermal expansion: In addition to the influence of the cooling and heating engine on the spindle thermal expansion, the spindle speed and cutting force during the processing have a great impact on the calorific value of the spindle bearing and the shaft core.
Tool change: There is an error in the fitting surface of the tool holder and the spindle during the tool change process.

Tool holder and chuck deflection: The tool holder and the chuck itself have static accuracy errors. With the high-speed operation of the spindle, the tool holder and the chuck will be affected by centrifugal force.
Tool setting instrument: the precision error of the tool setting instrument itself, the error between the static tool setting and the dynamic machining of the tool.
Tool: length, diameter error, concentricity and shape error of the tool itself.
