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.
Milling:
- In milling, the focus was on various milling strategies, including an outer contour with multiple tools, an angled surface, a slot with a circular arc, and a complex inner contour. Additionally, drilling operations and an M6 thread were included.
Please note: The video are only available in German.
