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 non-linear 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.

Jul 30, 2010nbsp018332when you say plunging i think you are drilling a round bottom hole. the rpm for a 0.500quot would be 2400 rpm. 43000.500quot2400 for drilling i use an exception of 50, so 1200 rpm. but plunging any endmill directly into the material is hard. you basicly have to slow it down till it stops chattering or the chatter is exceptable.
