Several inspection methods for precision metal stamping parts 'hardware'

There are several inspection methods for precision metal stamping parts. Dongguan Hardware teaches you the secrets of inspecting precision metal 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 metal stamping part along the longitudinal direction of the precision metal 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. 2. Whetstone polishing 1. First, wipe the surface of the outer covering precision metal stamping parts with clean gauze, and then use oilstone (20×20×100mm or larger) for polishing, and use it in places with arcs and hard-to-reach places. Grinding relatively small oilstone (for example: 8×100mm semi-circular oilstone) 2. The choice of oilstone 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 precision metal stamping parts. Some special places can also be supplemented with horizontal grinding.
