20 the diameter of carbide ball end milling, milling of ordinary steel material, the number of suitable feed cutting speed I? I use CNC machining center
Ordinary milling machine can not say, the speed does not come easily collapse knife.
Is it made for curved surfaces? Do you have 3000 surface to feed, probably around 2500, according to the engagement you and of course, a ball head knife can not eat very deep, if can eat deep side milling (side milling per 1 mm deviation are not the problem, considering the partial too much is not done, the surface processing is not good, I have 50 side rough machining, finish milling again 5 or brighter) in general is to face milling knife, I generally used in surface semi finishing and finishing,,,, (to ask you to work much to such a rough condition?)
Rpm is recommended for 1000 rpm / minFeed 0.2 mm / revAccording to the dynamic cutting machine.
