Abstract

In a process to de-burr the edges of a calibrated passage, and to adjust the cross sectional area of the passage to a calibrated dimension, the passage is exposed to a forced supply of an abrasive fluid. Before the abrasive fluid makes contact with the passage, the fluid is presented to the passage at the normal angle to the passage inlet.
