The GB-200 tumbling drum (hereinafter referred to as the tumbling drum) is a rotating container filled with abrasive material. Tumbling is designed to improve the quality of the surfaces of parts in a rotating drum with the addition of an abrasive. It is used for rounding edges, removing burrs (after stamping, cutting with a guillotine, cutting with a band saw), scale and flash (after plasma cutting, autogen), rust, molding earth and more.
The GB-200 and GB-300 tumbling drums are equipped with frequency converters for smooth start-up and changing the drum speed.
Tumbling is the process of cleaning and pre-treatment of the surface of a part. It is divided into two types: dry and wet. When dry tumbling, dry tumbling fillers are used.
During wet tumbling, various buffer solutions are added to the fillers. The material and shape of the tumbling fillers, as well as the buffer solution, are selected based on the material, the shape of the part and the required surface quality. Steel shot, slag, grinding wheel breakage, pebbles and special types of abrasives can be used as an abrasive, depending on the technology used. The duration of the tumbling cycle, the type of abrasive, the ratio of abrasive and parts are determined experimentally.
