A method for vibratory finishing of blade profiles in a double-layer integral bladed disk

Abstract

This invention relates to a method for vibratory finishing of double-layer integral bladed disks, specifically including: selecting a vibratory finishing machine tool based on the structure of the integral bladed disk: a centerless island rotary vibratory finishing machine; protecting the edges of the double-layer integral bladed disk blades; performing long-term vibratory finishing on the double-layer integral bladed disk blades; removing the U-shaped rubber protective sleeve; polishing the protected parts of the double-layer integral bladed disk blades; and performing short-term vibratory finishing on the double-layer integral bladed disk blades. This invention achieves blade edge protection, extends the vibratory finishing time, and allows most of the blade surface to be finished by vibratory finishing, significantly reducing the workload of manual polishing and solving the problem of long manual polishing cycles for double-layer integral bladed disks. This method can shorten the total processing cycle to 30%; greatly improves processing efficiency and surface integrity, shortens the development cycle; ensures the blade dimensions are within acceptable limits, and avoids dimensional deviations caused by vibratory finishing.
