Abstract
A machine for resurfacing the air-foil surfaces of turbine vanes and the like, comprising a base and a carriage movable over the base toward a work-performing station thereof. The base carries a power-driven abrasive belt which extends past the work-performing station, for engagement with the air-foil surface of the vane to be resurfaced. The latter is rotatably mounted on the carriage so as to be capable of turning during its engagement with the belt. The movement of the carriage over the base is governed by a cam and cam follower on the two parts, respectively, and a linkage is provided for effecting simultaneous synchronous turning of the cam and the vane. The arrangement is such that the position of the carriage with respect to the base is determined by the rotary position of the cam, and thus the contour of the latter affects the amount of resurfacing of the vane which occurs.
