The Essence of Micro-Abrasive Blasting
There are many variables that affect the results you will get from the micro-abrasive
blasting process. In order to get the most from your MicroBlaster, a thorough
understanding of these factors is essential.
The single most important factor in getting the maximum benefit from your
MicroBlaster is proper abrasive selection.
With the right abrasive, you can lightly
clean soft materials or deburr machined metal parts.
Once the correct abrasive is chosen, the remaining factors that affect the abrasive
actions are: the number of particles striking the work area, the velocity of the particles,
and the angle of the blast. These factors are controlled by the MicroBlaster through the
following operator selections:

Tank Orifice Size

Nozzle Size

Nozzle to Work Distance

Angle of Nozzle to Work Surface

Air Pressure

Powder Flow Adjustment Setting

Bypass orifice
Table 3-1 gives a brief overview of all of these essential factors. Each of them is
discussed in detail on the following pages, beginning with abrasive selection.
