Blasting machining method and blast machining device

Abstract

The disclosure concerns a blasting method achieving antistatic effect and increasing processing amount. In the method, 0.06 cc/min to 150 cc/min, that is, a relatively small amount of liquid is introduced into the blast nozzle and atomized by causing it to strike with the compressed gas flowing through the blast nozzle or the compressed gas ejected from the blast nozzle, and the atomized liquid is ejected together with the compressed gas and the abrasive onto the workpiece. Since the relatively small amount of the atomized liquid is quickly evaporated into water vapor, humidity in a working space is increased, thereby generation of static electricity is prevented. A vaporization heat is absorbed during evaporation then the workpiece is cooled, accordingly, absorption of strike energy from the abrasive due to softening of the surface of the workpiece is prevented, as a result, the processing amount is improved.

Dependencies are inferred from the claim text.
