Reduce Semi-finishing of Face Milling

High accuracy surface finishing x double sided 4 cutting edges
Fine surface quality even skipped semi-finishing process.

Q. How come semi-finishing process can be reduced?

A.
Since all blades are off by 0.05 mm in the axial direction, there is no need for pre-processing that leaves a small cut by using semi-finishing.
The final edge will be finished the process with itself.
