METHOD FOR DRUM RUMBLING OF PRECISION PARTS

摘要

FIELD: machine building.;SUBSTANCE: invention relates to machine building and can be used for rumbling parts with complex configuration in drum. Parts are loaded in bulk into a rattler drum, the working medium is added and rotation is performed around the horizontal axis at the specified frequency. Working medium used is a mixture of the following composition: jet fuel in amount of 15…35 % of rumbling drum volume, ceramic rattling bodies in amount of 50…65 % of the volume of the rumbling drum and a mixture of abrasive pastes in amount of 30…100 g. After loading parts and working medium, rattler drum is tightly closed. Combination of composition of mixture of abrasive pastes and rotation frequency of rattler drum is pre-selected for each type of parts.;EFFECT: as a result, the efficiency of the rumbling process and the quality of processing parts with complex configuration are improved.;4 cl, 3 ex
