              Turning:

              • In turning, the focus was on several typical machining operations, including facing and longitudinal turning of the outer contour, roughing and finishing of the inner contour, as well as threading an internal thread M36 with a 1.5 mm pitch. Additionally, a 24 mm hole was drilled.

              Please note: The video are only available in German.
