Claims19
A method of abrading a specimen, comprising:
- positioning a specimen below a funnel, the funnel having a top end and a bottom end, the top end comprising a funnel mouth with a mouth bore, the bottom end comprising a funnel stem with a stem bore, the bottom end opposite the top end wherein the funnel stem is directly coupled to the funnel mouth and the stem bore is aligned with and in direct communication with the funnel mouth bore, the funnel stem comprises an orifice structure extending below the funnel mouth within the funnel stem, the orifice structure having a through-bore and an outlet opposite the top end, the specimen being a select distance below the bottom end of the funnel, adjusting a distance between the orifice structure outlet from the bottom end of the funnel to set an abrasion distance between the orifice structure outlet and the specimen to a select value;
- supplying a flow of gas through the funnel and the orifice structure;
- and dumping an abrasive material into top end of the funnel, wherein the abrasive material passes through the orifice structure and the orifice structure outlet to strike and abrade a select area of the specimen;
- and removing spent abrasive material from the funnel through a vacuum line.
