• What is a ball end mill? –

Jun 09, 2020 What is the advantage of a ball end mill? The roughing process was performed using high-feed milling, characterized for the very high feed per tooth of 1.2 mm/z and the small axial depth of cut. The main advantage of this milling type was that no big stairs were produced in roughing, so the semi-finishing operation was eliminated
