MicroBlasting is extremely efficient and precise, so it is hardly likely you will need to recycle abrasive, but it is important to know the risk involved. Unlike grit or bead blasting, a MicroBlasting system can only cycle abrasive once. Abrasive should not be reclaimed and reprocessed for a second pass because:The blasting process causes abrasive media to break down very quickly. It won’t be the same abrasive on a second pass! Abrasive easily absorbs any moisture available in the air. It may clump in your blaster! Pieces of your part’s substrate often mix in and contaminate the abrasive. This could cause uneven results and even damage your part surface.
Hardness is rated from A-Z with ‘A’ being the weakest bond and ‘Z’ being the strongest. A weak bond is preferred for grinding harder materials while a stronger bond is desired for softer materials. A typical weak bond
