Wuxi Xishan District Hardware Stamping Parts Factory, dimensional tolerance + stamping parts precision can reach 0.01mm

Regarding the dimensional tolerances of stamping parts, the technical staff of Wuxi Xishan District Hardware Stamping Parts Factory once introduced, Xiaoshuo compiled some information, and let me share with you what dimensional tolerances are: 'GB/T13914-2002 Dimensional Tolerance of Stamping Parts' stipulates The dimensional tolerance of stamping parts has been improved. The dimensional tolerances are respectively specified for flat stamping parts and forming stamping parts. The dimensional tolerance value of stamping parts is related to the two dimensions of stamping part size and plate thickness, and on the other hand, it is related to the accuracy level. Flat stamping parts dimensional tolerance: divided into 11 grades, represented by ST1 to ST11, among which ST represents the flat stamping part dimensional tolerance, and the tolerance grade code is indicated by Arabic numerals. From ST1 to ST11, the accuracy level decreases in order. Dimensional tolerance of forming stamping parts: forming stamping parts are divided into 10 accuracy grades, which are represented by FT1 to FT10, where FT represents the dimensional tolerance of forming stamping parts, and the Arabic numerals indicate the tolerance level. From FT1 to FT10, the accuracy grades decrease in order. Limit deviation of stamping parts: The hole size is pressed as 0, the upper deviation is the lower deviation plus the dimensional tolerance; the shaft size specifies that the upper deviation is the basic deviation, and the value is 0, and the lower deviation is the upper deviation minus the dimensional tolerance. For hole center distance, hole edge distance, bending, drawing length, height, etc., the upper and lower deviations are specified as half of the dimensional tolerance.
