Table machines are best suited for the large and heavy or delicate parts. A table blast machine can be a single diameter table up to 12', twin tables or a series of smaller tables that oscillate independently.
The double door machines and smaller satellite tables allow continuous loading and blasting. Manual or crane loading is optimal for this machine type. Advantages are apparent in size and weight. Also with brass or softer type metals that would be damaged in a tumbling operation.
