FIELD: processes and equipment for cleaning, possibly hard-to-reach surfaces of articles, mainly of complex-shape articles subjected to hardening by micro-arc oxidizing.
SUBSTANCE: method comprises steps of using working agent moved by means of impeller mounted in housing secured to shaft mounted through joint assembly on drive unit. Guiding housing is in the form of enlarged cone with apex angle 45-70° and with holes on its whole surface consisting 25-30% of cone surface passing to cylindrical one and then to narrowing cone with apex angle 10-15°. Pulp in the form of water solution containing 20-30% of abrasive particles is used as working agent. The last is moved by two stages while using at first stage abrasive particles with size 60 - 200 micrometers and at second stage using abrasive particles with size 30-60 micrometers.
EFFECT: enhanced quality of cleaning, increased useful life period of articles.
