Large turn-mill machines are being used to produce massive parts such as crankshafts for ships and trains. This video shows a side-milling operation for such a crankshaft being performed on a Weingärtner machine. The cutting tool used in the turn-milling pass is a 4.72-inch-diameter milling cutter from Austrian cutting tool supplier LMT Boehlerit that has approximately 80 inserts.

These tools, which are especially for machining turbine blades, impellers, blisks and in moldmaking applications, feature forms with large radii in the cutting area of the mills, allowing a large axial depth of cut during pre-finishing and finishing operations.
