How to check the quality of metal stamping-

Metal stamping is the process of forming materials and is the main processing method of batch metal stamping. After the stamping parts are manufactured, when inspecting the processing of precision mechanical parts, it is necessary to know the inspection methods of precision parts processing. So what are the inspection methods for metal stamping? 1. The surface roughness of the metal stamping parts is tested using the sample block comparison method for comparison and judgment. 2. For the measurement method of the inner diameter of the metal stamping parts, when measuring the inner diameter of the parts, only need to measure the three parts in the circumferential direction and make a record at the same time. When the length of the same diameter is greater than 40mm, the cylindricity should be checked. Within the range of the length of the same diameter, two positions with a larger interval should be taken for measurement. Calculate the cylindricity error 3. The flatness test is tested by the metering method. Three adjustable supports are placed on the plate, and the measuring surface of the part is placed on the support point. Adjust the support point so that the three points are of equal height, and the meter is printed. The measured peak and valley value is the flatness error of the plane.
