Deburring is a very large challenge in the machining of metals and can limit the production process.
Wet blasting has been used as a suitable technology for removing burrs from difficult to reach places, given the flow of abrasive and its ability to achieve uniform finishes.
Being able to alter the abrasive used (typically spherical) and the water and air pressures allows users to create very hard or soft deburring conditions that limit the rounding or damage to edges that can occur with alternative methods.
Generally speaking, wet blasting is most effective at removing light burrs with a very fine aluminum oxide media and heavy burrs using a stainless steel or ceramic media.
