Description

What are Vibro Peening / Dot Peening / Vibro Engraving / Pin Marking Services?

Vibro Peening (or Dot Peening) is the process of a rapidly vibrating carbide cutter marking into the surface of a part. When the mark is viewed under a loupe, one will see a series of microscopic dots pushed together, but when viewed by the naked eye, the mark will appear to be a continuous line.
