During the processing of china cnc mold machining, some things need to determine their fineness in order to process them better.
1. Scale accuracy refers to the degree of conformity between the actual size of the processed part and the center of the tolerance zone of the part size.
Scale accuracy is controlled by scale tolerances. Scale tolerance is the allowable variation in the size of parts in mold processing. In the case of the same basic scale, the smaller the scale tolerance, the higher the scale accuracy.
2. Shape accuracy refers to the degree of conformity between the actual geometric shape of the surface of the mold part after mold processing and the ideal geometric shape.
The items for appraising shape accuracy include straightness, flatness, roundness, cylindricity, and line generalization. The shape accuracy is controlled by shape tolerances. Except for roundness and cylindricity, which are divided into 13 precision grades, the other shape tolerances are divided into 12 precision grades. Level 1 is the highest and level 12 is the lowest.
