The critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed. Get Price

With CNC milling, the radius of your end mill is the radius of any internal corner, so you will almost never have a perfectly square corner on the inside of a milled object. Smaller and smaller end mills can be used for each pass to clean up an edge and get the part to the final dimension and shape.

Bull end mills are simply corner radius end mill cutters. These radius end mills are single ended tools used for making corner radii at the bottom of a milled shoulder. Corner radius end mill cutters have a stronger milling edge than square end mills, so feed rates may be increased and yield longer tool life and greater productivity.

Also, how to generate male or radii with a ball end mill, easily, quickly and accurately, in a vertical mill. For example, you can machine a 1/4" diameter radius on the corner of a piece of material, using a 1/4, 5/16, 3/8, or 1/2" diameter or other size ball end mill. (Also works with the side of an end mill.)

In a turning operation, an aluminum workpart is reduced from a radius of 26mm to a radius of 24mm. If the lathe is set at 1500rpm the tool edge lasts just long enough to cut 50 parts taking 4 minutes each. If the lathe is slowed to 1/3rd that speed (500rpm) the tool can now make it through an amazing 1400 parts, but it takes 3times longer per part.
