FIELD: metal working. SUBSTANCE: apparatus has three struts, mounted on a base. Supporting basic members in the form of shaped formers, arranged mutually opposite, are secured to two adjacent struts. The shaped formers for determining an outer profile of the blade are secured rigidly, and the shaped formers for determining an inner profile are mounted with a possibility of reciprocation motion, parallel to a plane of the base. A wedge mechanism for searching and fixing an optimal position of the blade blank is mounted on a third strut. This mechanism is in the form of spring-loaded wedge, that may be moved for adjustment along guides and it is being moved relative to an end of the shaped former for determining an inner profile of the blade. EFFECT: high accuracy of working basic surface of complex-shaped articles. 1 cl, 2 dwg
