A sandblasting apparatus includes a chamber defining a cavity, a support assembly received in the cavity, a first sandblasting assembly, and a second sandblasting assembly. The support assembly includes a plurality of pairs of elongated support plates for holding a plate-shaped workpiece therebetween. The support plates are moveable along a vertical direction and a first horizontal direction. The first sandblasting assembly is configured for spraying sand downwardly toward the plate-shaped workpiece so as to cut the plate-shaped workpiece into a plurality of workpiece stripes. The second sandblasting assembly is configured for spaying sand toward the workpiece stripes along a second horizontal direction perpendicular to the first horizontal direction so as to cut each of the workpiece stripes into workpiece block, and processing the workpiece blocks into cylindrical workpieces. |
