Stamping is the process of forming materials. It is the main processing method for batch small hardware processing. When small hardware is made, when inspecting precision mechanical parts processing, you need to know the inspection method of precision parts processing. What are the inspection methods for small hardware stampings ?
1. The surface roughness test uses the sample comparison method for comparison and judgment.
2.Inner diameter measurement method When measuring the inner diameter of a part, just measure 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, a cylindricity check should be performed, and within a range of the length of the same diameter, two positions with larger intervals should be obtained for measurement. Calculate Cylindricity Error
3. The flatness is tested by the meter test method. Three adjustable supports are placed on the flat plate, and the parts are placed on the support points with the measurement surface facing up. The peak-to-valley value is the flatness error of the plane. For more information, please contact us: 18927415118
