FIELD: process engineering.
SUBSTANCE: invention relates to machine building and may be used for grinding gas turbine engine blade body curved edges. Blade is swung through definite angle about its lengthwise axis. Narrow grinding tape adjoining machined surface is displaced along blade body. Grinding is performed in following angular position of body curvilinear edge contact part by grinding tape. The latter oscillates in direction perpendicular to blade body lengthwise axis to rests upon spaced apart thrust rollers.
EFFECT: higher efficiency of grinding.
