Wuxi metal stamping processing plant, the knowledge of stamping accuracy division + stamping accuracy can reach 0.01mm

Wuxi metal stamping processing factory said that the dimensional tolerances are specified in accordance with 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 accuracy grade. Let me take a look at the following: 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 represented 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. The limit deviation of stamping parts: the hole size press deviation is 0, the upper deviation is the lower deviation plus the dimensional tolerance; the shaft size specifies that the upper deviation is the basic deviation, the value is 0, and the lower deviation is the upper deviation minus the dimensional tolerance. The upper and lower deviations of the distance between the holes, the edge distance of the holes, the length of bending and drawing, the height, etc. are stipulated as half of the dimensional tolerance. Hardware, 15 years of focus on Wuxi metal stamping processing plant, 20,000+ sets of customized stamping die production experience, monthly processing capacity of 100+ sets of molds, hundreds of precision processing and production equipment, daily production capacity of 3 million punches, and silk-like stamping accuracy ± 0.01mm, the raw materials are imported and the original national standard factory, and 16 quality inspections are strictly controlled. It can quickly solve time-critical problems for you, solve stamping accuracy problems, and solve production quality problems. Choose, choose rest assured!
