Dongguan Hardware teaches you the secrets of inspecting precision stamping parts

Wipe the surface of the outer cover with clean gauze. The inspector should 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. 1. First wipe the surface of the outer covering precision stampings with clean gauze, and then use oilstone (20×20×100mm or larger) for polishing, and use relatively small oilstone for arcs and hard-to-reach places. Grinding (for example: 8×100mm semi-circular whetstone) 2. The choice of whetstone particle size depends on the surface condition (such as roughness, galvanizing, 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. If you want to know more methods, welcome to consult
