摘要：FIELD: process engineering.SUBSTANCE: invention relates to abrasive processing and can be used in sandblasting of inner surfaces of different diameters and lengths. Sealed working area is created un cylindrical surface section with the help of two shutters with abrasive material filled therein. Compressed air is forced via nozzles arranged in symmetry about sealed working area centre to allow continuous circulation of abrasive-air mix. Compressed air is forced to working area at 3-10 atm. Processing is performed at displacement of sealed working are along the article processed surface.EFFECT: higher efficiency and effective non-polluting surface processing.1 dwg
