Machining Cast iron In a Lathe or Mill - STEAMSHED

Nov 28, 2019  Cast iron machining in a lathe or mill needs a very slow speed to cut it properly – too high and there will be sparks everywhere and your tools will need re-sharpening very quickly. As a general rule of thumb, to get a smoother finish on cast iron, you tend to need a finer tip on your cutting tool with very slow transition along the work.
