FIELD: process engineering.
SUBSTANCE: invention relates to machine building and can be used in finishing the blades of has turbine engines and similar parts. Revolving grinding wheel is brought in contact with processed surface and displaced stepwise in lengthwise axis of blade displaced across grinding wheel rotary axis. Grinding wheel is turned in fixed step through the angle of 3 to 5 degrees about axis extending through wheel center and central point of wheel and processed surface contact spot. Then, grinding wheel is imparted extra swinging motion relative to said axis through the angle of 2 to 5 degrees. Invention covers relationships for determination of velocities of grinding wheel swing motion and translation steps.
EFFECT: higher surface quality of blades.
