FIELD: technological processes.
SUBSTANCE: invention relates to the field of machine building and may be used to process bands, rolls and other large-size cylindrical parts, in particular in paper-making production, in production of cement. Installation comprises frame with guides of longitudinal stroke, table of longitudinal stroke, motor-reducer of longitudinal stroke table drive and table of transverse stroke. At the latter electric motor of continuous abrasive tape master pulley main drive is installed, and also spring-loaded slave pulley, which is arranged with tightener and fork. Axle of slave pulley is arranged in fork having body and cylindrical part, which is telescopically joined to tightener. Tightener is connected by means of traction rod to fork body. Drive of longitudinal stroke table is arranged in the form of chain transmission.
EFFECT: improved accuracy of processing and reduced roughness of processed surface.
