Abstract (en)

[origin: EP3061567A1] Provided is a blast machining method in which static electricity-preventing effects coexist with processed volume-increasing effects. A liquid such as water is introduced in relatively small volumes of 0.06 cc/min-150 cc/min to a blast nozzle (8) provided in a blast machining device. The introduced liquid is atomized by causing the liquid to collide with a high speed compressed gas stream flowing inside the blast nozzle (8) or a high speed compressed gas stream jetted from the blast nozzle (8). The atomized liquid is jetted towards the workpiece (W) along with the compressed gas and an abrasive. As a result of the jetted liquid evaporating easily because the liquid is atomized and jetted in this manner and the volume of liquid supplied is relatively small, humidity inside the work chamber increases and generation of static electricity is limited. Additionally, the workpiece is cooled by vaporization heat being consumed during evaporation and absorption of the impact energy of the abrasive that occurs as a result of the softening of the workpiece surface due to heat generated by collision with the abrasive is limited and processed volume (cut volume) is improved.
