FIELD: turbines.
SUBSTANCE: invention relates to abrasive processing and can be used for arc strip plate segment electrochemical finishing, to be installed around turbine plant steam turbine rotor. Device to clamp said segment comprises concave support unit, detachable end units, made with possibility of installation on concave supporting unit opposite ends to enable attachment of first and last plates, and detachable face plates attached to concave supporting unit opposite sides. In space formed between said elements soft material is arranged, selected from group comprising rubber, polymer and foam. Provided are bracket for securing of plate segment in it and installation in said space and stabilizing plates for plate segment plates fixing. Disclosed also device version with convex supporting unit.
EFFECT: higher quality of plate segment finishing due to reduction of its deformation.
