Mechanical deburring and blunting of blade edges
SE Ivchenko-Progress has adopted the technology of mechanical deburring and edge-blunting.
The technology affords the possibility to debur and blunt the airfoil edges of gas turbine engine rotor blades from Ti and heat-proof alloys by means of an OSBORN abrasive brush after finishing.
Deburring with the brush will become 5-time less labor intensive compared to using scraper, with the treatment quality being stable.
