Glass Bead Peening
Glass bead is a cost effective and versatile media that can be utilized for peening, metal cleaning, finishing, and light deburring.
Glass Bead used by National Peening & Technical Metal Finishing meets the requirements of AMS 2431/6.
- Rapid results: clean, finish, peen and deburr in one step
- Controlled results: clean finish without significant metal removal or changing tolerances
- Versatile: create a wide range of reproducible surface finishes
- Economical: can be recycled/reused many times
- Chemically inert: no ferrous or other residues
