Ball End Mill Speeds Practical Machinist
Dec 29, 2009 I took a series of machining classes at a community college in CA years ago. The simple guidance given for cutting steel with HSS was 100sfm at the largest diameter. Approximating pi allows the simple formula of 4 x cutting speed (sfm) / diameter (inches). For form cutters like your ball endmill, the recommendation was to cut that rpm in half.

Variables In Ball Mill Operation Paul O Abbe174
The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are nonlinear or have paradoxical effects on the end results. In ball milling of dry solids the main independent variables are mill diameter, mill speed, media size, solids loading and residence time.
