This discovery was the birth of the synthetic graphite industry. At approximately the same time that Mr. Acheson was experimenting with the manufacture of synthetic graphite electrodes, Mr. Riddle (the founder of Asbury Graphite Mills, Inc.) was converting a waterpowered mill, formally used to grind flour, into a natural graphite grinding mill.

Natural graphite is a soft material that conventional milling methods fail to grind into nanoparticles. We found that adding NaCl into graphite during milling allows obtaining graphene nanoflakes of about 50 × 200 nm 2 as evidenced by Transmission Electron Microscope (TEM). NaCl particles are substantially brittle and harder than graphite, serving as milling agents by both helping to chop ...

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.

Over the years, alternative procedures to the Bond grindability test have been proposed aiming to avoid the need for the standard mill or to reduce and simplify the grinding procedure. Some of them use the standard mill, while others are based on a nonstandard mill or computation techniques. Therefore, papers targeting to propose a better alternative claim to improve validity, to reduce test ...

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).
