Surface conditions after rough machining
(The reason of semi-finishing elimination)

General machine tools

Rough surface because of machining with R3 ball end mill
(Semi-finishing is necessary)

High speed machine

Fine surface because of machining with R1 ball end mill
(Semi-finishing is not necessary)
