China CNC Machining accuracy is mainly reflected in the following aspects: size accuracy, geometry precision and mutual position precision, which includes geometrical precision roundness, straightness and flatness. Mutual position precision including parallelism and perpendicularity and concentricity etc. What are the methods to get the CNC vowin.cn/en/News/news1251.html' target='_blank'>machining accuracy? 

Dimensional precision: the main methods such as test cutting, adjusting method, fixed size method and automatic control method. 

Geometrical shape precision: the method of trajectory method, forming method and development method and so on.

Mutual position precision: the main methods are direct installation method, positive and fixture installation method and so on.
