沖壓模具,加工中心加工，大連機械加工的精度，主要是體現(xiàn)在以下這幾個方面，為尺寸精度、幾何形狀精度和相互位置精度，其中幾何形狀精度包括圓度、直線度以及平面度等，相互位置精度包括平行度、垂直度以及同軸度等。

The precision of stamping die processing center and Dalian mechanical processing is mainly reflected in the following aspects: dimensional accuracy, geometric shape accuracy, and mutual position accuracy. Geometric shape accuracy includes roundness, straightness, and flatness, while mutual position accuracy includes parallelism, perpendicularity, and coaxiality.
