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.

Method for grinding side portion of stacked hard, brittle material substrate
An elastic abrasive with abrasive grains dispersed in or adhered to an elastic base material is ejected toward a side portion of a substrate together with compressed air. The elastic abrasive is ejected toward a predetermined processing area centered on a processing point in an ejection direction that intersects a widthwise line at the processing point and that forms a predetermined inclination angle selected from a range of 2° to 60° relative to a contact line. Moreover, an ejection nozzle and the workpiece are moved relatively to each other so that the processing area is moved at a fixed speed in a circumferential direction of the workpiece and so that the ejection direction is maintained at each processing point after moving. If multiple stacked substrates are to be processed, the processing area is moved at a fixed speed also in a widthwise direction of the substrates.

Process for producing gel-like abrasive material and gel-like abrasive material
An abrasive that can impart a mirror finish, glossiness, or the like to a surface of a workpiece by blasting is provided. A crosslinked polyrotaxane compound having a network structure where crosslinking points are circular molecules of polyrotaxane and also having abrasive grains dispersedly mixed therein is obtained by causing chemical bonding between the circular molecules of the polyrotaxane in a state where the abrasive grains and the polyrotaxane are mixed. Then, the crosslinked polyrotaxane compound is granulated to a predetermined grain diameter to obtain a gel-like abrasive where a part of the dispersedly mixed abrasive grain is exposed at the surface. By using the thus-obtained gel-like abrasive in blasting by projecting the abrasive at an angle tilted with respect to a surface of a workpiece, mirror finishing or the like is possible without making the surface of the workpiece pearskin-like.

PROCESS FOR PRODUCING GEL-LIKE ABRASIVE MATERIAL AND GEL-LIKE ABRASIVE MATERIAL
Disclosed is a gel-like abrasive material that can perform planishing, gloss surface formation and the like of a surface of a workpiece by blasting. Also disclosed is a process for producing the gel-like abrasive material. In such a state that abrasive grains and polyrotaxane are present in a mixed state, cyclic molecules in the polyrotaxane are chemically bonded to each other to give a crosslinked polyrotaxane compound which has a network structure comprising the cyclic molecules as crosslink points and in which the abrasive grains have been dispersed and mixed. The crosslinked polyrotaxane compound is granulated to a predetermined grain size to obtain a gel-like abrasive material having a surface on which a part of the dispersed and mixed abrasive grains have been exposed. When the gel-like abrasive material thus obtained is used in blasting in which the abrasive material is projected at an inclined angle to the surface of the workpiece, the workpiece can be worked to have a specular surface or the like without matt finishing of the surface of the workpiece.
In blasting with an abrasive containing liquid to confer elasticity, the abrasive from which liquid evaporates in the course of continuance use is uniformly supplied with liquid. Liquid for swelling an elastic abrasive is sprayed in an air flow for transporting the abrasive in a blasting machine 1 including an abrasive-recovery duct 91 communicating between a bottom of a cabinet 2 and an abrasive-recovery tank 3, the abrasive-recovery tank 3, a compressed gas before being introduced into a blasting gun 8, and so forth. Since the abrasive being transported in the air flow is separated into individual particles, each abrasive can be uniformly supplied with liquid.
A bottom wall surface of a blasting chamber of a blasting machine provided with hoppers for recovering an abrasive is formed at a lowest possible position. A cabinet 3 of a blasting machine 1 is compartmentalized at a predetermined position into an upper space and a lower space by mesh members (21, 22) that allow the abrasive to pass therethrough to form a blasting chamber 2 having a bottom wall surface 20 defined by the mesh members (21, 22). Hoppers 10 substantially shaped like an inverted quadrangular pyramid are disposed below the mesh members (21, 22) such that top portions of the hoppers 10 are opened toward the mesh members (21, 22) and that the bottom end of each of the hoppers 10 is made to communicate with suction means, such as a dust collector, through a recovery pipe 30.
