The use of a C2 grade of carbide is recommended for wear resistance. If it's hard in any way, it can prove to be difficult, if not impossible, without grinding. Once the skin is gone, if the iron is soft, you can machine by pretty much any means you desire. Cast iron isn't hard to machine, and has its own built in lubrication (free graphite).

Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semiautogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushinggrinding circuit with three stages of crushing followed by ball mills or ...

These end mills have a diamond or diamondlike coating for machining abrasive material, such as carbon fiber, fiberglass, and graphite. Made of solid carbide, they are harder, stronger, and more wear resistant than highspeed steel and cobalt steel for the longest life and best finish. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to ...

Only diamond (preferable) or carbide tools may be used for cutting graphite. Graphite and carbon are generally machined dry without using Cutting fluids (coolants). If coolants are used in some machining operations (grinding, honing, polishing) the workpiece should be dried at 300400°F (150200°C) to remove liquids absorbed by the material.
