Metal Finishing

In precision machining, surface preparation for bonding is a key application for Airbrasive^®. The photo shows an acoustic sensor being cleaned prior to bonding the ceramic insert to its metal outer layer. Any contaminants, corrosion, or oxidation must be removed before the bonding process. In micro abrasive blasting the surface is roughened, making it easier to bond to.

The photos below show two examples where metal was machined to form cross drilled holes as well as slots, feather like burrs, or rough edges have developed and need to be eliminated. This process, done by hand, is not only time consuming, but tiresome. On the other hand, a quick blast with the micro abrasive machine takes the rough edges and burrs right out.

Burrs also develop when parts need to be threaded, as shown in this illustration. One quick blast by our micro abrasive machine will remove the burrs without degrading the surface. Metal surfaces must be prepared prior to bonding or plating. The inside of this piece must be cleaned of any contaminants that would prevent adhesion.
