Glass Beads
Glass beads remove no material but compact the surface and produce the characteristic matt satin sheen. They are produced by Kuhmichel Abrasiv. On pallets there are 10 items to choose from.
Material and technical data
Glass beads are spherical, not angular — that is the whole difference. Instead of knocking material out, they rebound and compact the surface layer. The result is an evenly matt, slightly work-hardened surface with no loss of material and no change in the part's dimensions. They run in pressure as well as injector blast systems.
Grain sizes and applications
Main grain ranges run from 40–70 µm to 600–800 µm, plus the finest step at 0–50 µm. Fine beads produce the higher gloss level, coarser ones work faster and clean better. For aerospace the standards AMS 2431/6, MIL-G-9954 and NF L 06-831 are met, and a Rolls-Royce CSS8 customer approval is in place.
Why the pallet
A pallet of glass beads pays off for large cabinets, several machines or an initial fill — a lot of material enters the circuit at once. For topping up during operation the bag is usually enough. The other pallet articles: palletised goods.
What matters when choosing
Glass beads are a reusable medium: they survive many cycles as long as the machine reliably screens out fragments and dust. Where they reach their limit is adherent mill scale or old coating — that calls for an angular medium as a first stage.
Alternatives in the range
For removing scale and old paint White Fused Alumina or Garnet Sand are the first stage; where work must proceed without loss of substance, Nutshell Granules is the gentler option. The whole blasting media programme compares every grade.
