To provide method and device for blasting an abrasive material to an abrasive material spraying object without damaging the object and uniformly blasting the abrasive material to the object with little time and cost.

By this method, the abrasive material is blasted to a rotation symmetrical member, more particularly, a metal member. The method includes steps of: putting each member 1 in an abrasive material blasting chamber 2; moving each member 1 along a carrying path through the abrasive blasting chamber 2; blasting the abrasive material to each member 1 from three surfaces, that is, upper surface and both of side surfaces by an abrasive material blasting means; rotating each member 1 around the rotary axis while passing each member 1 through the abrasive material spraying chamber 2; turning the rotary axis sideways in relation to a carrying direction of each member 1 at the time; and taking out each member 1 blasted with the abrasive material at an exit of the abrasive material blasting chamber 2.
