How many inspection methods are there for precision stamping parts? Dongguan Hardware teaches you the secrets of inspection

There are several inspection methods for precision stamping parts. Dongguan Hardware teaches you the secrets of testing precision stamping parts. 1. Touch inspection Wipe the surface of the outer cover with clean gauze. The inspector needs to wear touch gloves to touch the surface of the precision stamping part along the longitudinal direction of the precision stamping part. This inspection method depends on the inspector's experience. If necessary, oilstone can be used to polish the detected suspicious area and verify it, but this method can be regarded as an effective quick inspection method. Second, oilstone polishing 1. First, wipe the surface of the outer covering precision stamping parts with a clean gauze. Then polish with oilstone (20×20×100mm or larger), and polish with relatively small oilstone (for example: 8×100mm semi-circular oilstone) in areas with arcs and hard-to-reach places. 2. Oilstone particle size The choice depends on the surface condition (such as roughness, galvanization, etc.). It is recommended to use fine-grained oilstone. The direction of whetstone grinding is basically along the longitudinal direction, and it fits well on the surface of the precision stamping parts. Some special places can also be supplemented with horizontal grinding. The above is about the care of precision stamping parts, if you need to know more questions, welcome to consult:
