FIELD: process engineering.
SUBSTANCE: blade half stuff is made with allowance for further polishing. Coarse grinding is made to remove 0.1 mm- to 0.8 mm-thick layer, preferable from of 0.2 to 0.4 mm. Then during final polishing, 0.01 mm- to 0.2 mm-thick layer is removed using the device with abrasive belt fitted on tangential contact wheel actuated to preset RPM. Aforesaid abrasive belt consists of super-abrasive grains.
EFFECT: required profile of jet aircraft blades.
