Dry Burnishing
Dry burnishing (drag burnishing)
Blanks are dry burnished either in a batch process, where the blanks are mechanically vibrated by means of a dry burnishing medium, or by individual tensioning where the blanks are drawn through the dry burnishing medium.
Dry burnishing is also known as drag burnishing
The burnishing medium can be impregnated with different burnishing pastes depending on the metal that is to be burnished.
Blanks that are dry burnished are often pre-treated with vibration deburring.
