Jun 26, 2017· Ball Nose Milling Without a Tilt Angle. Ball nose end mills are ideal for machining 3-dimensional contour shapes typically found in the mold and die industry, the manufacturing of turbine blades, and fulfilling general part radius requirements.To properly employ a ball nose end mill (with no tilt angle) and gain the optimal tool life and part finish, follow the 2-step process below (see Figure 1).
Ball Mill Finish Calculator. The Ball Mill Finish Calculator can be used when an end mill with a full radius (a ball mill) is used on a contoured surface. The tool radius on each side of the cut will leave stock referred to as a scallop.
The calculator will automatically provide the necessary speed and feed in the green fields. For assistance setting up your milling program, contact a Dapra applications specialist or call (800) 243-3344. Click here to download a chart of recommended Ball Nose cutting speeds and feeds (PDF).
