FIELD: turbines or turbomachines.
SUBSTANCE: invention relates to repair of worn-out labyrinth seals of turbomachines and can be used in oil and gas, power and other industries servicing gas turbine equipment. Method is carried out by means of a device for rolling a ridge of a labyrinth seal, at that, the labyrinth seal ridge is fixed between the clamping rollers located on one axis, by means of the bar fixed in the screw-cutting lathe cutter holder, after which ridge rolling cycle is performed for gradual increase of its height in screw-cutting lathe with tightening of nut, adjusting compression force, and performing intermediate measurement of axial clearances to achieve the drawing parameters of the ridge.
EFFECT: invention allows restoring operating parameters of worn-out labyrinth seals of turbomachines and increasing service life of labyrinth seal.
