Spindle Speeds & Cast Iron Machining - Practical Machinist

If you look at any break lathe set up to cut cast-iron brake drums or rotors, you'll see they use a flat carbide insert, no top rake. And you can get a nice smooth clean surface using them. Once the tool dulls, you will be able to feel small splinters in the metal that may be invisible without a magnifying glass.

Challenges In Cutting CGI : Modern Machine Shop

Conversely, gray cast iron possesses high thermal conductivity, which allows heat to be carried away with the chip during a machining operation. The casting crust on a CGI component has a ferritic structure, causing material to stick to the tool’s cutting edge. This doesn’t occur with gray cast iron because it has a pearlitic structure.
