Ball size as initial charge. commercial ball sizes 10 – 150 mm; number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. for the initial chargin of a mill, coghill and devaney (1937) defined the ball size as a function of the top size of the feed, i.e., d †“v = 0.40 ...
Nov 01, 2003 the ballnose end mill is a special sort of tool. its ability to mill up and down the contours of complex surfaces makes it invaluable to mold shops and other makers of 3d forms. and yet, the tool is lacking in a capability one might take for granted in other cutters: the ability to machine a flat surface.
