Vorrichtung zum Erzeugen von schrägen Tieflochbohrungen in metallischen Werkstücken mit konvexer Oberfläche |
摘要 |
The drill bit ( 14 ) passes through a drilling bush ( 2 ) for guiding said drill bit. The drilling bush ( 22 ) is pressed against the workpiece ( 10 ). However, the drilling bush does not terminate flush with the workpiece, but comprises a linear supporting edge ( 28 ) that overlaps the apex of the curvature of the workpiece. This prevents the drilling bush from sliding off a curvature of the workpiece surface. |
