Further, the object 2 to be processed is held through a rubber glove 1 that is difficult to be polished by the abrasive material 8 during processing. This rubber glove 1 is attached to the side wall of the processing chamber 7. At this time, the workpiece 2 is insulated from the ground by the rubber glove 1, and static electricity is generated on the surface of the workpiece 2 due to friction between the surface of the workpiece 2, the abrasive material 8, and the high-pressure air 4. It was structured to accumulate.

The conventional sandblasting device described above sprays abrasive material from a nozzle onto the surface of the workpiece at high speed while holding the workpiece using rubber gloves that do not easily abrade the workpiece. Static electricity generated by friction between the surface of the object and the abrasive material and high-pressure air accumulates on the surface of the object, which is insulated from the ground by the rubber gloves.If this amount of charge exceeds the dielectric strength of the rubber gloves, The drawback is that electric current flows through the rubber and causes a shock to the human body.
