How does the stamping parts factory inspect the metal stamping parts?

Stamping is the process of processing materials into shape, and is the main processing method for batch metal processing. After the hardware is made, how does the stamping factory inspect the metal stamping parts? Need to know the inspection methods for precision parts processing, so what are the inspection methods for precision metal stamping parts? 1. The surface roughness detection adopts the sample block comparison method for comparison and judgment. 2. Measuring method of inner diameter When measuring the inner diameter of a part, only need to measure it at three locations 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. When metal stamping is carried out, it is necessary to strictly require processing standards and strict requirements for inspection standards. The above is how the stamping parts factory inspects the metal stamping parts. For your reference only.
