Bore grinding device, has finishing tool including active trimming face attached to trimming plate and projecting radially relative to body, so as to cooperate with concave surface of bore, where actuating unit acts on trimming plate

摘要

The device has a body including a cylindrical housing axially oriented and opening radially outward. A finishing tool includes a trimming plate having a shape complementary to that of the housing, where the tool includes an active trimming face (9g) attached to the trimming plate and projecting radially relative to the body, so as to cooperate with a concave surface of a bore. An actuating unit acts on the trimming plate for moving the plate radially outwardly, where the actuating unit includes an actuator whose output movement member acts on the face radially vis-a-vis the trimming plate.
