冲压模具,加工中心加工，大连机械加工的精度，主要是体现在以下这几个方面，为尺寸精度、几何形状精度和相互位置精度，其中几何形状精度包括圆度、直线度以及平面度等，相互位置精度包括平行度、笔直度以及同轴度等。

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.
