Re: Carbide - Surface Finish - 9A

Ondrej Krejci <okrejci@...>


The theory behind cutting with carbide is that it tears instead of shears, the exclusion being polished positive rake inserts used mostly for aluminium.

And so, higher speeds lead to lower tool tip pressures and better finishes; hence, finishers have small nose radii.

You may want to check the grades of carbide you are using if possible.  There are various charts on the web.

Best of Luck,
