### Surfacing Ball Endmills - Practical Machinist

Dec 19, 2011 · If your after a real good surface finish and you feel the part geometry needs to be surfaced with a ball endmill, a very good alternative is the "flat" ball from LMT Fette. It is basically a ball endmill with a very tiny flat cutting portion on the nose to avoid the zero surface feet at the tip, for example a 6mm dia ball has around a 1mm flat.

### Sphere - Wikipedia

A sphere (from Greek σφαῖρα — sphaira, "globe, ball") is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball (viz., analogous to the circular objects in two dimensions, where a " circle " circumscribes its "disk" ). Like a circle in a two-dimensional space,...
