Hello,
I have parts need turning and milling ,so I think to buy a lathe 2 spindles with live tooling
However,Somebody told me if your milling by live tooling is more than 20% ,you will end with a lot of maintenance to these live toolings
how much this sounds right?is there any science behind that
I need the live tooling to drill holes and tap also port tool which is similar to drilling
is there relation between the power I need to machine by live tooling and time of machining or in other world the material removal
how can I verify that?

Thanks
